Re: [Gimp-user] GIMP hints for astrophotography tweaking

One common operation is "stacking": as you add layer N to the image,
make the layer mask's transparency be 1/N.  So the first layer is
the background at 100%, the next layer goes in at 50%, the next at
33%, etc.  This enhances the contrast of a bunch of short exposures
without enhancing the noise much; it apparently also sharpens
lunar/planetary images, by reducing the effect of temporary bad
seeing in one part of the image.

I don't know of a gimp plugin to do stacking, but it would be fairly
trivial to write.  (I'm not really an astrophotographer myself and
have never stacked more than four images, so I didn't look very hard
for a plugin, nor bothered to write one.)

Of course, you have to make sure all the images are accurately
aligned (easy if you have pinpoint stars, not so easy if you're
shooting something with soft edges like Jupiter).  2.2's transform
tool previews should make this important part a LOT easier.  

It would be a bit easier still if there were a way to alternate
between rotation (transform tool) and translation (the move tool)
while previewing without having to actually do the rotation (there's
presumably a quality loss every time you free-rotate an image) but
the only way I've found is to remember the rotation amount in the
transform tool, cancel, select the move tool, move the layer, then
transform again and type in the rotation where you left off.  That
comes up a lot with panoramas, too.  Anyone know a better way to
combine rotation and translation?

Though with a real astrophotography CCD and a rock solid mount
you may not need any rotation/translation.

I'm in the same situation as Pasi.  I often open an image wherever
it originally lives, then after I make a change, save to to whatever
working directory I'm using.  I guess a better model now would be
to go to a shell and cp the file to the new location before touching
it with gimp, but with 2.0 and 1.x it was no problem, so I got in
the habit of staying within gimp for the whole job.

> It could be 'easily' remedied by showing some kind of a list with

"Favorites" or "Bookmarks" that were always visible would help some
of the time, but not all of the time: I can't bookmark every
directory where I ever save images, so I tend to bookmark the
top of a hierarchy, then navigate down within that hierarchy.
Navigating down is hard in this dialog (it's easy if directory
names are unique, but not if there are any name conflicts) and
usually I end up just typing the whole subdirectory path and
hoping I don't mistype.

Naming conflicts in files are another reason I frequently expand
the dialog.  I often save successive images to similar names. 
For instance, I might have lesson6-step1.jpg, lesson6-step2.jpg,
lesson7-step1, etc.  The autocomplete in the dialog will only
complete up up to the first conflict, and after that, my choices are:
- type out the whole "6-step2.jpg" part (with the old dialog,
  I could have typed 6 and not had to type "-step.jpg");
- arrow down through the list until I get to a file with a
  similar name (and then hit return, reminding myself that return in
  this case doesn't actually save to the name I chose, only loads
  that name into the text field and I'll still be able to edit it; I
  have a hard time making myself hit return in a save as dialog when
  I'm pointed at a file that already exists and I don't want to
  overwrite); or
- expand the dialog, scroll down, and click on one of the existing
  filenames so that I can edit it.

The last frequently ends up being easiest -- though it's still harder
than autocomplete with the old dialog, since it requires the mouse.

I might be missing something.  When should I hit the tab key?
For instance, if I have a bunch of existing files called
gimptxt-[0-7].jpg and I want to save this one as gimptxt-8.jpg.
I type gim, and the dropdown pops up.  If I hit tab now, nothing
different happens -- the dropdown disappears for a second then comes
back, and nothing new is added to the filename in the text field.

Sven Neumann writes:

I haven't, because it would still be an awkward solution.  I'd have
to do the same thing I described for similar filenames: select a
last-used directory with a similar name, hit return, then edit the
name to get the name of the new directory.  And if the list was in
most-recently-used order, which would make sense from a design
standpoint, that would actually make it more difficult for my most
common usage: I'd probably have a last-used list that was out of
order (lesson9, then lesson8, then lesson10, then lesson6) which
would be awkward to read and navigate.

If you added a last-used list, I'd probably use it sometimes; but
most of the time I'd probably just end up typing the whole filename
rather than switching to the mouse to choose the directory, then back
to the keyboard to edit the directory and finish typing the filename.

Try Image->Mode->Indexed, and play with the number of colors to
get it as small as you can manage while still looking good.  
Then save it, still using png format.

Full-color pngs are large, but indexed png can be quite small.

Cleaning up the noise from the scan, as you've been doing, can help

worth trying the conversion to indexed before cleaning up the

That would be really helpful!  I'm forever wondering whether I have

Toggling selection visibility is something I do all the time, from

I'm sure some people would like that, but I wouldn't want to have to

Spacebar to switch temporarily to move is awfully useful. I didn't
know about it until this discussion, but I've often wanted something
like that -- I'm forever switching between move and something else,
for instance when I'm creating lots of different text layers and
need to position each one. If you change spacebar to pan, I hope you'll
consider investing some other key with this "temporary move tool"
meaning. Now that I've known about it for a couple days I'm already
sorry to have to give it up!

Do a lot of gimp users not have a middle mouse button? Maybe tablet
users who don't want to put down the stylus and switch to a mouse?
(That would be understandable.) Or is this just because ... that
other program does it that way, and its users are used to it?

I don't even have that excuse. I press the spacebar all the time:
I use it as a no-op to make that image active (so Layers and other
dialogs will correspond to that image). I had dimly noticed that
"something changes in gimp windows" when I pressed it, but I never
thought to hold it down and really look at what was changing.
My only excuse is that I think of space as an autorepeating
character key, something I shouldn't hold down unless I want
some discrete action to happen repeatedly.

If discoverability is the problem, might it help to make it one of
the startup tips? That's probably worthwhile regardless of which
behavior ends up being bound to spacebar; spacebar to pan is
no more discoverable than spacebar to move (I'd be surprised
if most people who use a spacebar panner in any other program
discovered it on their own). 

I bet there are lots of other tips like that which would make good
startup tips.  Is http://wiki.gimp.org/gimp/FortuneCookies a good

Some of what you and Michael Chang describe seems foreign to me,
which made me wonder what platform you're on -- I think there are
platform differences between the printing plug-ins.

On Linux, printing is really straightforward. I'm in an XCF and
I do File->Print. I get a dialog saying that GIMP can't handle
layers and offering to export, and I say yes. That's just for the
printer; it doesn't flatten the layers in the current image or
otherwise change it (much like how saving to jpeg will flatten
layers in the saved file, but the file you're editing still has
all the layers intact).

When I agree to the Export, I get the gimp-print dialog which has
all the printer info, and a tab for Image/Output Settings where I
can select grayscale (since you mentioned wanting that) or click
Adjust Output to get lots of sliders for adjusting brightness, etc.

> Should I just save the image in .jpg format then print normal?

Saving in JPEG loses a little bit of information each time you save.
At least use a non-lossy format like PNG.  I'm not sure what "print
normal" means.

Sometimes it can take a lot of fiddling, and unfortunately a lot of
sample prints, to get a print to come out with the same brightness
balance you see on the screen. If you "Save Settings" from the
gimp-print Adjust Output dialog, the settings are remembered (or
at least they used to be), so once you find the mapping from your
monitor to your printer, you can probably use that with minimal
changes from then on.

I think having "color profiles" for your screen and your printer
will eventually be able to help with this (and I believe that's
being actively developed in GIMP), but I suspect that setting up the
color profiles in the first place will still be a time consuming
task. Maybe we'll be able to use pre-built profiles for common
printers and monitors. But I'm slightly dubious: I used to have two
monitors of the same model, which displayed colors quite
differently, perhaps due to age; and color inkjet printers vary
depending on the kind of paper you use.

If you need even more adjustment than that -- e.g. adjust the bright
areas but leave the darks unchanged -- you might have to use
something like the Curves tool with saved curves. This unfortunately
*would* mean you'd need to flatten the image, in order to apply the
curve to all layers. But you don't need to save the image as
flattened; you could edit the XCF, flatten, apply the curve, print,
then Revert it from the saved file. (Just be careful not to save
the file accidentally while it's flattened. But if you do that,
you can always Undo the flattening, then Save again ...)

michael chang writes:
> The GIMP's print module will only print the current layer by default. 

This must be a platform difference, and a different print plug-in
from the Linux gimp-print one I'm using. GIMP prints all layers

In what way did it screw them up?

The most common way is that they'll be out of focus -- the camera
is set to only focus on close things, and you pointed at something
far away so it couldn't focus.

You'll never be able to get a really sharp image out of that --
the information just isn't there in the photograph -- but if it's
not *too* far out of focus, Unsharp Mask can make it a bit better.
Play around with the settings (Unsharp Mask has a preview now,
which really helps).

If you have a lot of time to spend and really can't retake the
photos, there are other techniques for using Unsharp Mask or other
sharpening tools in conjunction with other tools (selections
or layer masks, for example) to get better control over how an
image gets sharpened. The term to google for is "sharpen"
or "sharpening" -- you may be able to find some helpful tutorials
with that keyword plus things like "photo", "blurry", "tutorial",
or "GIMP".  Don't limit yourself to GIMP tutorials; tutorials
for other image processing programs can often be applied to GIMP.

The screenshot window lets you set a delay in seconds.  You can
use that time to go back to the window you're shooting and pop up
whatever menus you need.

If the menu goes outside of the window it's in, you'll need to use
"full screen" or "region of your desktop" instead of "window" in
the screenshot dialog, otherwise you'll only get the part of the
menu that overlaps the window borders.

When you click ok in the dialog, you choose the window or region
immediately, then the delay starts, giving you time to place the
cursor or pop up any menus you need.

[Gimp-user] Crop Tool Use Cases

2005-08-23 Thread Akkana Peck
A discussion on IRC about the new crop tool revealed that there are
lots of different use cases for cropping. They're all important, and
it's important to make sure there's a list of them so that the new
crop tool will handle them.

Here's a start.  I hope people will jump in and fill in the details
for the ones I'm unclear on (the constrain case and the zealous
case) and add any other use cases I've missed.

- Crop to selection.
  (Handled fine by Image->Crop Images. This might be the most common
  case, and the one a lot of GIMP newbies will use until they discover
  the others.)

- Crop a small area of any size out of the middle of an image.
  (Handled fine by old and new crop tools.)

- Crop an area of constrained aspect ratio, letting you move or
  resize the crop rectangle to choose the right area.
  (I don't do this very much, but people ask for it all the time,
  and maybe I'd do it if it were easier.  Someone who needs/uses
  this should speak up with details on how it should work!)

- Crop an area out of an image, retaining one or more existing
  edges.
  (Handled well by old crop tool; difficult in current CVS.
  Making the crop tool stop at the image edges, like the old
  crop tool did, would fix this.)

- Crop a single layer image to the visible boundaries.
  (Handled by Autocrop, not by the crop tool.)

- Crop multiple layers to the visible boundaries.
  (In 2.2 it was roundabout: select all, click in the image, click
  From Selection, then click Auto Shrink. In CVS there's currently
  no way to do it. I'd like to see the Autocrop menu item handle
  all visible layers (is there some reason it shouldn't?, or see a
  similar item, like "Crop to Visible Layers", which does that.)

- I assume there's a use case for Zealous Crop, but I'm not clear
  what it is. When I try it I usually end up with an image with a
  bunch of blank layers because anything with information has been
  cropped away. Can a Zealous Crop user speak up?

Okay, crop users, tell me what I missed!

Mostly it involves trying to keep informed of changes, and being
ready to do a lot of last-minute revisions. Several early chapters
are already obsolete and will already have to be rewritten, but
I knew that was a possibility going in.

The UI coverage may not be perfect (and of course, any program can

change some UI detail compared to 2.4.0) but at least the book will

That very often means that you haven't configured the printer type
in the gimp-print dialog. It doesn't get your printer type from
CUPS or whatever other spooler you might be running; it defaults
to postscript, which for most inkjet printers results in printing
out a lot of postscript source. (I wish it defaulted to "No printer"
or something, and perhaps popped up a dialog asking the user to
set the printer type ... if it ever gets straightened out which
project owns the gimp-print dialog, perhaps I'll try adding that
myself.)

If you've already set gimp-print to the right printer type,
then I'm out of ideas and maybe someone with an HP can help.
What OS/distro are you running?

Selection is what you need to be learning about: you need to
selecting the flower and not the background, or vice versa,
so that you can run a lightening tool (brightness-contrast, levels,
or curves) on the background without affecting the flower.

There are lots of ways of selecting: you could use paths then turn
the path into a selection, or you could use select by color or
intelligent scissors to make an approximate selection, then use the
quick mask to fine tune it and get it perfect.

For any of these techniques (maybe not siox), zoom in a lot so you
can see what you're doing and make sure you get all the fine
details. That's why these tools are better than something like
Lasso select that doesn't let you zoom in.

If you can run the development version of GIMP (2.3), the new siox
tool works quite well for flowers against a contrasting background.

A couple other tips: you'll probably want a few pixels of feathering
(but you can feather a selection after the fact, from the Select
menu), and you'll want to use View->Toggle Selection (ctrl-T) a lot
to turn off the selection boundary while you're adjusting the
brightness of the background, to make sure you don't get an obvious
looking jump at the selection boundary (if you do, try feathering more).

That should give you enough to get you started, anyway.
Good luck!

Or maybe there's something wrong with the lens. I bought a little
Aiptek Pencam recently to use in places where I don't want to risk
a better camera (kayaking, hanging from model airplanes ...)
The center and lower right of the field is usually more or less
focused, but the left and upper left are always out of focus.
Apparently the lens is just installed poorly (I know these cameras
can take sharp images -- I've seen some). I hear it's possible
to disassemble the camera and fix the lens alignment, though I
haven't had time to try it yet. Of course, if this is your only
camera and you paid significant money for it you might be better
off trying a camera repair place.

(and the same with a digital print machine)

I wonder if they need EXIF information from the image? EXIF is a way
of storing information about a photo (date, exposure information,
camera information, thumbnail, etc.) inside a JPEG image.

You don't mention what version of GIMP you have (for a while it was
preserving EXIF, but that disappeared again in later version, alas)
but you might try using another program to compare the exif
information between a file straight off the camera and a file
you've edited with GIMP. 

If you have jhead, try:
  jhead -te camera_img.jpg edited_img.jpg
which transfers all the EXIF from the original file to the edited file.
Then see if that image works in the camera or print machine.

(jhead is in lots of linux distros already, and if not, it's at
http://www.sentex.net/~mwandel/jhead/ -- the other program, "exif",
doesn't appear to have an option to transfer all the EXIF from one
file to another, so jhead is probably a better option.)

In fact, I just tried that (my husband has a Sony camera) and
indeed, copying the EXIF from one of the original files made the
camera see the file and got rid of that "file error" message.
But here's the catch: the thumbnail that the camera shows is
part of the EXIF, so it's showing me the thumbnail from the
other image, not from the one I'm actually looking at. And it
seems to notice that they're different and not want to zoom in.

I think GIMP adds a thumbnail on its own when it saves (at least,
I remember seeing a checkbox for that in the JPEG Save As dialog).
If you experiment a bit you can probably find a way to copy all
the EXIF *except* the thumbnail (leaving that unchanged) so that
your Sony will be happy. With any luck GIMP will get better EXIF
support eventually, and will be able to handle this on its own ...

Someone asked me recently about scaling up cartoon images (e.g.
to turn a small carton image into desktop wallpaper) and had the
impression that something like this might work. But I wasn't
able to find any information on these techniques on the web.

For a cartoon, you start with sharp edges and fairly even colors,
so the problems aren't the same as with digital photos.
Although you can't get more information than was present
in the small image, are there techniques that let you scale
up while preserving edges, so for instance a thin sharp black
line becomes a thick sharp black line rather than a thick blurry
grey line? Scaling up in steps didn't seem to make much difference.
I thought perhaps indexing to a small number of colors might help,
but I still got too many greys on the edges of the blacks.
By playing with Levels I was able to sharpen up the scaled images
somewhat, but I wonder if there are better ways. Any tips?

The current 2.2 installer asks during the install, and defaults to
"no" for all file types except maybe XCF (which of course it should
claim). The defaults seem exactly right. Of course, if you check
them all on, then GIMP will claim all those file types, but that's
an action the user has to take.

If there's a case where GIMP makes those file associations even

It looks like your system isn't reading all the mouse positions,
only getting some of the mouse motion events.

There's a configuration option in the gimprc man page that might
be related:

I don't remember whether you said what platform you were on, but
it might be worth adding a line to your gimprc (that's a text file

not running, and add the line) and try both settings to see if one
of them makes it better.

Have you tried the gimp-print list? There's active development going
on with gutenprint, especially with the newer Epson photo printers,
and some of the colors are still being tuned. Check the archives to
see if your printer is one of the ones updated recently. You might
find a lot more people who know about color balance on specific
printers on that list.

I use gimp and gimp-print or gutenprint to print 8x10 wall photos
and greeting cards on an Epson C86, which probably isn't what you
would consider "serious printing". The colors are usually okay
though the default black level is sometimes too high (that might
have something to do with the paper; I haven't done much
experimenting yet).

Using layer modes, you can get an effect similar to what you're
describing: you can make overlapping areas of layers turn
colors that reflect the addition or subtraction of the two colors.
Unfortunately, blue and yellow don't combine to make green in either
addition or subtraction mode; they make white. Think about the RGB
values of the colors to understand why -- if you don't know the RGB
values of colors off the top of your head, watch the sliders in the
color chooser dialog when you select the colors to see how red,
green and blue combine to make each color. Blue is 00F, yellow is
FF0, and adding them makes white, FFF, instead of green, 0F0.

To get a better feel for how colors combine, try this exercise:
make a black background layer. On top of it, make three circles,
each in its own layer, one colored red, one green, and one blue.
Move the circles so that they overlap each other partially but not
completely. Now, in the Layers dialog, set each of the three circles
to Addition mode and watch how they combine. Play with circles of
different colors in different layer modes to see what happens.

Subtract mode does basically what colored filters would do to a
white light (do the circles exercise I described, but start with a
white background instead of black). Addition mode is what you would
see if you shone lights of different colors (e.g. a blue light and
a yellow light) onto the same surface. Unfortunately, in neither
mode will blue and yellow combine to make green, even though that
is the combination you'd expect if you're used to mixing paints.

Yikes! No, it's really easy in GIMP, and it's basically the same
steps as in a vector drawing program, except that you have to create
the layer explicitly (which a vector drawing program does with every
new object).

1. Open the photo.
2. Make a new layer (click the New button in the Layers dialog).
3. Use the rect select tool to select the rectangle.
4. Round the selection with "Rounded Rectangle" (in the Select menu).
5. Fill it with white (Edit->Fill with FG should do it if you
   haven't changed colors from the default).
6. Adjust opacity with the slider in the Layers dialog.
7. Add the text (which will be a third layer).

I didn't quite follow why you were using a layer mask, but it's
not needed for a simple task like this.

To eliminate the pixellation, use the paintbrush tool (which

But that doesn't solve the arrow problem. GIMP unfortunately has no
tool that creates arrowheads; you either have to draw them by hand,
or make a brush or separate image of the arrowhead you want to use;
then rotate it appropriately for the line you've drawn.
(Googling for gimp arrows got lots of hits for brushes that

It should be possible to make a gimp animated arrowhead brush that's

that: http://www.graphics-muse.com/gfxmuse/gfxarrows.html

When I saw the original request I was thinking of suggesting a
"sticky mouse" option, equivalent to the "sticky keys" option
available in X or at the OS level to make modifier keys toggle,
for one-handed (or one-fingered) users.

But I quickly realized that the cure would be worse than the
disease. If you made the left mouse button toggle every time it
was clicked, then every one-click operation becomes a two-click
operation; your total number of mouse clicks nearly doubles.
If you didn't have RSI before then, that would bring it on
for sure!

So it actually might make sense to implement such a feature
separately for drawing tools in graphics programs (as an option, of
course). If it was implemented at a systemwide level, it would have
to be smarter than merely making clicks sticky; for instance, you
could say that any drag of more than [threshold] pixels remains a
drag even if the button is released during the drag, until the
button is clicked again.

In case it isn't one of the problems that has already been
suggested: How are you moving the layer? Clicking on the move tool,
dragging the layer, then clicking on the perspective tool, or with
the spacebar, or some other way?

How are you copying the layer? Is it possible that it's a floating
layer when you run the perspective tool? (Even then it seems to work
for me in 2.2.8 and 2.3.10, but I could imagine it not working in
some versions.) Or that you have "Clip result" selected in the
Perspective tool?  (Though that gives pretty much the opposite
result from what you described: the layer is transformed but you can
only see the part that falls within the un-transformed layer
boundaries.) Definitely check all the tool options in case one of
them has been changed.

It's possible you're hitting a GIMP bug (what GIMP version are
you using?) but I expect a bug like that would have been noticed,
so it's probably more likely that there's a problem with tool
options, with which layer is selected, or something similar.

As I try to reproduce what you're seeing, I'm doing the following
(plus variations trying to reproduce the misbehavior):
* New Image
* Choose the Rect select tool
* Select a rectangle
* Fill with pattern
* Copy
  (the selection is still active, so this copies the selected
  rectangle instead of the whole layer, so you can skip the Autocrop
  Layer step. See the Note at the bottom of p. 154.)
* Paste
* Click New in Layers dialog
* Use Move tool to move it
* Choose the Perspective tool
* Click on the layer that was just moved
* Drag the handles
* Click Transform

Is that basically the same sequence you've been using?

If it helps, a little while ago in CVS builds I was seeing

and mysteriously snap into "expand from center" mode even when I
hadn't pressed any modifier keys, then would stay there.

I was sure it must be a bug, or a failed experiment: I have
confidence in the folks who are working on improving those tools.
And sure enough, it no longer happens in current CVS (and hasn't for
the past week or two). It looks like it was just a short-lived bug,
now squashed. Rect and ellipse select are working fine now.

I only use the default selector. I like the UI for the triangle
selector in theory (maybe because the hue slider is a circle),
but in practice it's too slow: it lags way behind my mouse drags,
even on my fastest machine. I don't find the others very useful.

I haven't used it in years, since I found out what sticky labels do

That doesn't quite work for me, because the contents of the source
image get applied to the layer mask too (where the source image was
blue but opaque, the destination won't be fully opaque).

But you can fix that by adding two steps: between steps 1 and 2,
turn on Keep Transparency (checkbox in the Layers dialog, called
Lock in 2.3) for the source image, then fill the source image with
white. Then copy, and what you paste later into the dest image's
layer mask will reflect only the alpha channel of the original.

(Don't get too put off by the number of steps. I skipped steps 4 and
5, but I was only using single layer images; maybe they're important
for the general case. And I skipped step 7 because it happens
automatically from step 6.)

This doesn't actually give you an image with an alpha channel, as
the OP asked; it gives you a layer with a layer mask that mimics the
original image's alpha channel. But "Merge visible layers" will turn
that layer mask into an alpha channel if you care about the difference.

It might be that your GIMP is including an old gimp-print plug-in from
4.2, but the larger package which includes all the printer drivers
is Gutenprint. A little checking with dpkg -S, dpkg -L and aptitude
search might solve that mystery if you're on Ubuntu as your signature

I think they're compatible (must be, if the distro installs them
that way) but the experts who would know for sure aren't here;
they're on the gimp-print/gutenprint devel list.
https://lists.sourceforge.net/lists/listinfo/gimp-print-devel
They'd also be the ones who would know whether or not a particular
printer model is supported. Glance at the archives first (at that same

Since you're starting with a bitmapped image anyway (a satellite
photo), GIMP is fine. Any problems you get from rescaling the trails
will also be problems when rescaling the image, so you wouldn't
get any advantage from using Inkscape.

I've used GIMP to make map overlays: for instance, a topographic map
layer, a trail map (converted from the park's online PDF), and a
geologic map layer (converted from a USGS PDF). Then I can adjust
the transparencies and colors of all the layers depending on which
combination I want to print out for a specific project. It's a lot
of work getting everything scaled just right (it would be so much
easier if this info was all available in open GIS formats that
worked in free mapping software ... maybe some day!) but the results
can be very useful.

The "Keep aspect ratio" toggle in the Crop tool's tool options is
what you want.

Unfortunately, in 2.2 "Keep aspect ratio" is tricky to use: you
turn it on, then drag in the image to crop and the checkbox turns
off again! It only works if you check it on after you've started
the crop, and by that time the crop rectangle is already the wrong
aspect ratio.

Here's a workaround: click in the image. The crop dialog comes up.
In the dialog, click "From Selection": this will set the crop
rectangle to the whole image. Then go to the tool options and
enable "Keep aspect ratio". Now you can adjust the upper left
and lower right of the crop rectangle and it will maintain the
image's aspect ratio.

This will all get a lot better in 2.4, with any luck. The crop tool
has been completely redesigned and is much better than 2.2 already,
though the aspect ratio part of it still needs some work.

If the rectangle doesn't line up quite right, try other selection
shapes too, like the free select (lasso) tool. Whatever shape you
use, you'll almost certainly want to add a lot of feathering to the
selection, otherwise you'll see a very sharp line at the edge of
the part you darkened.

If the area to be darkened isn't too large, you might get better
results with the Dodge/Burn tool, since this is exactly what it's
made for. To darken an area, set it to "Burn" rather than "Dodge" (I
know that seems backward -- it has to do with old paper darkrooms),
and set Mode to either Midtones or Highlights depending on how
bright the area is to begin with.  (Experiment with both and see
which works best). You'll probably want a large fuzzy brush.

You may have changed the clone tool's Alignment option (in tool

(Registered is useful when cloning from a different image or layer,

Sure, that's probably better; but with a lot of images you can bring
out much more vibrant color simply by using tools like brightness/
contrast, levels or curves, or by overlaying the image with itself
and playing with layer modes.

So to get a graduated filter effect, try making a duplicate layer
with a layer mask, then draw a black/white gradient on the layer
mask. Then you can operate on just the sky part using the various
brightness tools.

You could also use a graduated selection (e.g. draw a gradient on
the quickmask), but if you use a separate layer with a layer mask
you can change the "graduated filter" after the fact, making it
more gradual, or lower, or cutting out that tree sticking up above
the horizon, or whatever other editing you need, without losing the
contrast effect you've already done on the sky.

One thing I've done is calculate the default value before calling
script-fu-register. But of course that doesn't help if you
want a new default calculated each time the dialog comes up based
on some property of the image; you can only calculate a one-time

The new GTK print system wasn't introduced into GIMP until after
"Beginning GIMP" went to press, so the dialogs shown in the book are the
Gutenprint ones, not the new default print dialog that comes from GTK.

You can still get the Gutenprint plug-in from the project's web site
http://gutenprint.sourceforge.net/ -- or you may be able to
install it as part of your distro. Ubuntu Gutsy seems to install
Gutenprint by default, instead of the gtk print plug-in, but I don't
know what other distros are doing with 2.4. You can have both
installed -- they'll show up in the File menu as "Print" and "Print
with Gutenprint".

I use Gutenprint myself, because of the control it gives me over
resolution, paper type, and placement on the page, its live preview,
and because GTK print is still a bit buggy; but GTK's print has
improved quite a bit recently, so it may yet become usable.

I just watch the numbers that show in the tool options. Much more
convenient than the old dialog that always came up on top of the image,
since tool options stay docked beneath the Toolbox.

And the Fixed: Aspect Ratio works great for keeping it square
(or 4x3 or whatever other aspect ratio I need). I find fixed aspect

I'm assuming you're talking about the "marching ants" when you say
selection borders, and it's an interesting suggestion, though it
might take a UI person to decide exactly how they should change
to indicate fuzziness.

But there's a solution for your friend in the meantime: the
Quickmask. Click on that inconspicuous little square down at the
bottom left of the image window, in the corner between the scrollbar
and the ruler. That switches to Quickmask mode, in which anything
that is *not* selected is red. You can see fuzzy borders really well
with the quickmask -- I often use it when I want to check whether
I've feathered a selection enough. Click in the same place (now it
looks like a red square) to get out of quickmask mode.

While you're in quickmask mode, you can also do useful things like
changing the selection by painting with the various paint tools.

For me (on Linux), Shift locks the aspect ratio, but only if I press

it doesn't do anything as far as I can tell. Is that intentional?

Me too :-) except Michael has already covered it so well.
The only thing I'll add is that when I first started, I was
worried about one of Apress' guidelines that said they wanted
a particular dpi, so I started out being careful to set the
dpi after taking screenshots. I was also sending high-resolution
versions of non-screenshot images.

Once we got rolling, it turned out that their layout people scaled
each image to an appropriate size on the page, and nobody really
cared what dpi the images claimed to have. As long as I took normal
GIMP screenshots of reasonably-sized windows, everybody was happy.

The Apress style guide also had warnings about not using Windows
Print Screen, and more warnings about various other programs to
avoid under Windows (mostly color depth issues, I believe).  None
of that was a problem with the GIMP screenshots, which worked fine.

- Make a layer mask (Layer->Mask->Add Layer Mask..., or you can use
  the context menu in the Layers dialog). Let it default to White
  (full opacity).

- Click on the gradient (blend) tool in the Toolbox.
  Make sure your fg/bg colors are Black and White (the defaults)
  and that the gradient is FG to BG (the default).

- In the image window, hold the Ctrl key down, then mouse down anywhere
  along the very top of the image, and drag straight down (the Ctrl
  key will make it easy to stay exactly vertical) to the middle of
  the image, then release the mouse button.

You're basically done (it should be transparent just as you
described), but you'll probably want one more step:

- In the Layers dialog, click on the tiny preview that shows your
  image, to make sure that it and not the layer mask next to it is
  active. You want the image preview to be outlined in white, and
  the mask preview to be outlined in black, not vice versa.
  (This saves you from getting "You are about to save a layer mask"
  errors when you save.)

If you save it as anything but .xcf, you'll probably get warnings
about how layer masks aren't preserved, but don't worry about those.
If you don't want to see them you can Flatten before you save.

I've made business cards with GIMP: I wrote a script to generate an
image of the right aspect ratio, then another script to take one
such image and turn it into an image with the right aspect ratio
to be a US-Letter sized page to print with gutenprint. (It also
does various other types of labels, not just business cards.)
You might have to adjust the offsets a bit for your templates
and printer. Here are the scripts:

http://shallowsky.com/software/gimplabels/

To be honest, it's probably easier most of the time to use a program
that's designed for making labels and business cards, like gLabels;
or design one business card in gimp then import it into gLabels for
printing (or Open Office, even). Anyway, lots of options.

Here's a simpler method (no need for saving to a channel) that I
thought would work, but doesn't, and I'm not clear why:

1. Make the first selection. Click inside the rectangle to confirm it.

2. In the Rect Select tool options, switch to Subtract mode, Expand
from Center, and Fixed Aspect Ratio (current).

3. Click in the rectangle again to bring back the resize handles.

4. Resize to define the smaller rectangle (which will be subtracted
from the larger one.

The problem: when you first start the drag from a resize handle in
step 4, the boundaries jump to a rectangle that's not concentric
with the current one, with the positions seemingly random (at least,
I can't see any regularity to which handle creates jumps in which
direction).

Is that a bug? If it's not, why does it happen? (I'm seeing this
with the Ubuntu gimp 2.4.5.)

It's a fairly well known problem, at least among people who maintain
both a locally built gimp and the one installed from their distro.

The current 2.5 release notes have a reasonable description of what's
happening (which also apply to gimpshop or any version of gimp you
might want to build yourself while still keeping a system-installed
version), and how to fix it:
http://www.gimp.org/release-notes/gimp-2.5.html
(scroll down to "Installation").

Whoever builds that gimpshop packageshould probably be doing this,
though maybe they just assume that no one would ever want both gimp
and gimpshop on the same system (but in that case, it should be
marked as a conflict in the package dependencies, as you say).
Failing that, you could probably fix it by moving all the gimpshop
stuff to some other place and using a script like the one in the
2.5 release notes.

I'm not understanding you any more than the other two people
who have already replied, but I have a couple of guesses:

First, the magic word for "crosshatch indicating no data at all
exists" is "transparent" or "alpha" (never mind why "alpha" means
"transparent"; remembering it will make a lot of other things
easier). If you're cutting things out of an image and getting
white (or some other color) when you wanted to see the grey
checkerboard pattern, that means your image doesn't have an
"alpha channel" (in other words, it doesn't allow transparency).
Add one with Layer->Transparency->Add Alpha Channel. If that's
greyed out, then you already have an alpha channel and that's
not the problem.

Second, though you're saying "crop" I get the impression you might
actually be trying to select stuff and clear it (make it
transparent). Crop is when you start with a big image (e.g.
800x600), and you want to take only some rectangular portion of it,
to make a smaller but still rectangular image.

If you're trying to end up with a shape that's not rectangular --
e.g. cut away all the white area around some central object to
make everything transparent except the object -- then crop is not
what you want. In that case, what you want is to select the part
you want to cut away and do Edit->Clear (which will make it
transparent *if* your image already has an alpha channel, otherwise
it will just make it whatever background color you have set).
Alternately, select just the object you want, and do Edit->Copy
so you can paste it somewhere else.

If none of us has guessed right about what you're trying to do
and you're still frustrated, try telling us what sort of image
you're starting with and explaining the steps you *are*
following, what happens and what you expected to happen.
That might clear things up.

On Debian and Ubuntu, you can probably get the bitmapped X fonts
back by going to /etc/fonts/conf.d, removing the symlink to
../conf.avail/70-no-bitmaps.conf and replacing it with a symlink
to ../conf.avail/70-yes-bitmaps.conf. Depending on the distro,
you might also need to uncomment or comment a section in

If you get tired of drawing manually on the layer mask to keep only
the sky, there are ways of getting GIMP to select the sky for you.
Basically, you use Decompose to split the image into various aspects
(hue/saturation/value, red/green/blue or sometimes others) then
use one or more of those layers to help you make a layer mask.

There used to be a wonderful tutorial on that technique by Jenny Drake,
but unfortunately the site is no longer online. The Internet Archive
has the text of the tutorial but no inline images, but you can
read the text here:
http://web.archive.org/web/20050313031704/http://www.photojenic.co.uk/home-page/gimp-sky-colour.html

And Carol Spears wrote a good tutorial based on it which *does*
have images:
http://carol.gimp.org/gimp2/photography/sky/compose/

If you can forgive a brief commercial note, there will be a couple
of examples of the same technique in the 2nd edition of Beginning
GIMP (expected in late December). Now that I see Jenny's tutorial
is gone, maybe I'll try to find time to put some of it into a web

The "Marble madness" preset in GIMPressionist does something similar

I do that a lot too -- making desktop backgrounds for monitors of
several different sizes -- and I'm always irritated by how many steps
it takes.

I had never actually used those Save Tool Options presets, and your
message made me look into them -- I should have done that long ago!
It helps with the most tedious step. But still, there are quite a few
steps left, so it's still tedious. Getting this far inspired me to
try to automate more of the job, and the result is a python script:
http://shallowsky.com/software/gimp/wallpaper.py

The script has a list of resolutions it knows about (1680x1050,
1024x768, 1366x768 and so forth). You use rect select in the
original image (using tool presets to set the aspect ratio
correctly) and make a rectangular selection. Then call the script,
which registers in Image->Selection to Wallpaper. The script
compares its list of resolutions with the selection's aspect
ratio and picks the closest one. Then it copies the selection,
pastes it as a new image, and scales it to what it thinks is the
right size based on the aspect ratio. The original image is still
there so you can go back and do the next size/aspect ratio.

I know your task is a little different -- you don't have the Scale
step, so my script might not help you much. And using rect select
isn't really as good as using crop, because rect select doesn't stop
at the edges of the image, so you have to be super careful not to go
over when you make the selection. (I'll probably add something to
the script to correct for that, as well as adding something to save
automatically to a directory chosen based on the size.) But I thought
I'd share the script since it might give you ideas, or might help
someone else who does desktop backgrounds like I do.

Martin already answered your questions about units, so I'll just
address this part. I've done business cards and labels in gimp
(http://shallowsky.com/software/gimplabels/) and they can line up
if you get the distances right.

You have to make sure you have an image that matches the size of
your paper, and get the offsets right, of course.  I've tried to do 
labels where I made the image size match up to the outer edges of
the outer labels, then set the offsets in gutenprint, and it was
frustrating and never worked right.

I've only printed with gutenprint, where it's easy to see when
you're printing a full page with zero margins on any corner. I
couldn't get the same amount of control through gtkprint, though
it's gotten a *lot* better in the last few releases and maybe
it would work now. Another option, if you have trouble with gtkprint
not lining up, is to print to postscript or PDF, preview it to
make sure the page size and margins are what you expect, then
print that from another app.

Also, my inkjet printer (YMMV) varies quite a lot from page to page,
so even if I create a perfect template at the perfect size, printed
labels may not register exactly with the label sheet. So you
need to make sure any text doesn't go all the way out to the edges
of the label, and that any background is wide enough to spill over
the edges quite a bit. Drawing a neat box just inside the edges is
right out, unfortunately. Maybe some printers are better at that.

> That is not to knock Gimp.  I knew from the start that Gimping the project

That's exactly the right attitude. There are lots of apps designed
for printing labels and business cards, but I like having the option
of making them in GIMP because it gives me the option of printing at
high quality and high resolution. I always keep in mind that this
isn't really what gimp is for, so if I have to do a little extra
fiddling compared to glabels, it's my choice.

Do the green lines go away if you redraw the window? (For example,
cover it with another window then uncover it.) Do the two machines
have similar video cards?  

Artifacts like that are usually bugs in the video driver. I see

apparently some video drivers, especially the ati/radeon driver,
can't handle that quite right. (It may be the hardware not handling
it right -- looking at bugzilla it looks like the problem happens

Here's a bugzilla bug that discussed the problem, some time back,
with lots of duplicates, some of which have screenshots that look
a lot like yours:
http://bugzilla.gnome.org/show_bug.cgi?id=421466

A comment in that bug suggests adding the following line to your
gimprc file (located in your gimp profile, ~/.gimp-2.6/gimprc):

Try that and see if it helps.

The problem in this case may be that a lot of those patterns on

Okay, done. I started with save-anim-layers, but then during the
course of simplifying it to deal only with patterns I ended up
rewriting pretty much the whole thing.

http://shallowsky.com/software/gimp/save-pat-layers.scm

It still registers in Animation, as "Save layers as patterns".
Animation isn't the right place for it but it wasn't obvious
what would be better. Any thoughts?

Start with the original multi-layer image and run Animation->
Save layers as patterns, and it will save each of the layers
to your GIMP profile patterns directory with the appropriate
layer name. I've only tested it on one pattern (the animal one)
but it seems to work.

It does change the original image -- the layers stay autocropped,
I didn't bother to try to revert them since I figure most people
will just be closing that image anyway.

I'll put it on the registry after I get feedback on whether
it's working okay for anyone besides myself. I'd especially like
to hear whether it works on Windows, since it builds up paths with
"/" (which I think script-fu is supposed to translate automatically).

You don't mention what platform you're on, or what version of GIMP
or where you got it. But GIMP has several different ways of opening
remote files -- gvfs, gnome-vfs, libcurl, wget -- and if your gimp
is compiled to use a method you don't have, that'll cause errors.
The choice is made at compile time; the runtime code doesn't fall
back to use other methods if the preferred method fails.

For instance, Ubuntu's GIMP is compiled to need gvfs, so if you
don't have that installed (for instance, if you're running Xubuntu
or some other window manager instead of a Gnome desktop) then
Open Location or dragging from a browser probably won't work
unless you build your own gimp with --without-gvfs.

I see the same thing. The problem is the Sobel filter.
If you go through the steps in chalk.scm by hand, everything is fine
until the point where it calls plug-in-sobel, at which point the
text vanishes.

Apparently the Sobel filter in 2.6 (which is very different from
the 2.4 Sobel) doesn't work on transparent layers any more --
in other words, it won't detect edges in alpha, only in colors.
If you duplicate the black background layer and merge it with the
white chalk layer before running Sobel, or set the background color
to white and then remove alpha on the text layer, it works.
I don't know whether that change to Sobel was intentional.

Thanks! What a nice thing to say. :-)

I should probably mention that that LinuxChix class is old (I think
it was based on GIMP 2.2) and in 2.6, the Lasso tool is *much*
easier to use. You no longer have to select in one go -- you can
drag for a while, stop, scroll the view, drag some more. You can
also mix freehand dragging with clicking to make line segments,
like you would with the Path tool. It's like the best parts of
the old Lasso combined with Paths.

I never used the old Lasso tool much, because I couldn't zoom in
and scroll around while selecting, but in 2.6 I use it quite a lot. 
If you haven't used the new Lasso because you didn't like the old
one, give the new one a try!

(Unfortunately for me the Lasso was changed to late to make it in

Yes, that's exactly the way to do it. And the best way to do that
is to make a layer mask on the upper layer, then paint black, white
or grey on the layer mask according to how transparent you want to
make it (black for transparent, white for opaque).

Not at all!  Layer masks make this very straightforward in GIMP.

For instance, start with step 4 of the selective colorization
tutorial: http://gimp.org/tutorials/Selective_Color/
Or try a short video tutorial I made demonstrating layer masks:

Have you used Shaped gradients? I think they'll help a lot.

If you haven't used them, try selecting one contour area, then
use the Gradient tool with Shape=Shaped, and drag from one edge
of the contour to the other. Neat, huh? But it's not quite what
you want, because it goes from white to black to white again, not
from white at one contour to black at the next.

Here's a way I found to do that.  It may still take a lot of steps,
but I think you'll get a better result than the smudging/airbrushing
method you mentioned:

Start with an image that has just the contour lines -- e.g.
black contour lines on a white background.

Use the magic wand tool and select the area within one contour
(the white area between two sets of black contour lines).

Save this selection somehow (e.g. switch to Quickmask mode, Copy, then
Paste and make it a new layer and turn visibility off on that layer;
or save it as a channel in the Channels dialog).

Still in magic wand, switch to Add mode and add the area in the next
contour up. (Or down, your choice.)

You may also need to select the line between the contours. If it's
antialiased, it may be faster to use quickmask and the paintbrush
rather than magic wand here. Or you may not need to select it at all.

Make a new layer (where you'll be drawing the gradient).

On the new layer, make a layer mask. Copy that original selection
you made, of a single contour area, and paste it into the mask.
Then click on the layer preview. Now you'll be drawing into the
new layer, but you'll only see the part corresponding to the current
contour.

In the Gradient tool with Shape=Shaped, drag across your contour
to make the shaped gradient.

I ended up with something like this:
http://gimpbook.com/tmp/contours.jpg
You can clean up the edges of the layer mask as needed (those
white edges between the blue edge and the black contour line).
The important thing is that the shaped gradient gives you a nice fade
in the right directions without your needing to airbrush anything.

The closest I've found is View->Snap to Canvas Edges. It's not
perfect -- you still have to be fairly careful and occasionally
it doesn't snap at all -- but it will certainly help you avoid
going over the edges.

In 2.6, you have to set it on each image separately. In 2.8 it will
be possible to make that the default.  Though you may not want that;
I find I always want it for Rect Select, but it gets in the way
for the Move tool, so I have to keep toggling the option.

Or if you want automatic outlining, you might also experiment with

"Edge" is the easiest to preview since you can compare several

The regular (GTK) print dialog should see CUPS-registered printers.
Gutenprint doesn't -- for Gutenprint you have to add each printer
yourself, and it doesn't have drivers for a lot of printers that
CUPS supports just fine, so you have to use "Postscript Level II"
and do without any special features the printer might otherwise offer.
For Gutenprint, try asking on the gimp-print list (they're friendly)
to find out if there's a way to install a ppd manually.

I've had a lot of trouble controlling details like edges and borders.
With my HP and the GTK print dialog, I managed briefly to get
borderless (full bleed) prints, but something changed in the CUPS
settings and now I get unpredictable margin sizes, and I haven't
found the magic setting to turn borderless back on. I didn't
have any better luck when I had an Epson and used Gutenprint.
Accurate printing from GIMP still involves some luck and black magic.

Because JPEG isn't meant to be saved at 100% quality.

The JPEG FAQ, http://www.faqs.org/faqs/jpeg-faq/part1/section-5.html, says:

  Except for experimental purposes, never go above about Q 95; using Q 100
  will produce a file two or three times as large as Q 95, but of hardly any
  better quality.  Q 100 is a mathematical limit rather than a useful setting.
  If you see a file made with Q 100, it's a pretty sure sign that the maker
  didn't know what he/she was doing.

Do a web search on
  jpeg quality "100%"
and you'll find lots of detailed discussions of this.

GIMP's "Show preview in image window" check box is extremely
helpful, and lets you see the trade-off in quality versus size.
It's too bad it's not enabled by default.

Except that you can't use that in GIMP 2.7 on a lot of window

ever change desktops, the toolbox and all docks disappear, and it's

So the "Normal window" setting really isn't usable any more, and

Try this:

- Select by color and click on one of the lines.

- Selection to Path.

- Select None.

- Scale the image up to the desired size.

- Path to selection.

- Fill the selection with black.

It doesn't work for everything, but for a line drawing or solid
colored block figure, sometimes you can get amazingly smooth edges
that way.

http://www.netmarketshare.com/report.aspx?qprid=17 makes it look

But http://browsersize.googlelabs.com/ seems to be saying that more

"bigskypa" is probably assuming that everybody runs their browser
in fullscreen mode, so that it takes up the full monitor resolution.
Really, a better measure is how big people's actual browser windows are.

But a web page needs to  be able to adjust to different browser sizes.
If your layout changes in unpredictable ways because you resized your
browser window, you need to fix your HTML layout.

That's one reason why GIMP isn't a good web design tool, though it's
great for making individual graphics to use as part of a web page.
Perhaps try an HTML forum to figure out where your HTML is going wrong?

In addition to the suggestions others have already made, the

http://docs.gimp.org/en/gimp-getting-unstuck.html
When you get stuck (and it happens to all of us sometimes),
it's helpful to go through that list. There are a few other
possibilities that aren't in that list (for example, drawing
tool modes) but it covers the most common causes.

You should have a text size button in Tool Options.
See Figure 13.170 in the online GIMP manual,

If you've closed your Tool Options somehow (normally it's docked

I don't know where this Turboprint option is, but if it's a separate
Print option in GIMP's File menu, my guess is that Turboprint is
installing its own Print plug-in, and you need to copy the one
it installed for 2.6 to 2.7.

It might be installed in your profile directory, e.g.
~/.gimp-2.6/plug-ins, or it might be installed in a system location,
e.g. /usr/lib/gimp/2.0/plug-ins. Check your GIMP Preferences in 2.6,
under Files > Plug-ins, for possible locations.

I'm guessing you're talking about making an image map. You can create
HTML imagemaps in GIMP using Filters->Web->Image Map... -- see the
documentation at http://docs.gimp.org/2.6/en/plug-in-imagemap.html.

But if you're having trouble importing the map into Kompozer, you
might have better luck asking on a Kompozer list. They'll probably
need specifics of what goes wrong when you try to import it: the
