As you said, the moment when you press the modifier key is important.  For 
effecting the shape, have it pressed while dragging the shape, esp. in the 
moment you let go of the mouse button.  If you simply want to change the 
selection mode (such as add, subtract or intersect), make sure the modifier 
key is pressed while you _push the mouse button down_, you can let go of the 
key once the mouse button is down.

I hope this helps, Daniel

It's a problem in some (most?) window managers, not with Linux itself.  
Personally, my preferred option is to change the WM's behaviour to move 
windows with the windows key + mouse instead of Alt + mouse.

I'm not sure if this is possible at all, especially not if from within GIMP.

It's the one with the flying (i.e. moving) window.  But I'm afraid some 
malicous company grabbed it as their trade mark without even implementing the 
moving of windows properly or understanding the concepts of modern window 
managers.  Since penguins can't fly (but slide, at least downhill), there are 
some keyboards with those cute little creatures on instead.

Are we talking about the same thing?  This thread's issue is (or so it seems 
to me) about moving the _content_ of a selection, as described in 
http://docs.gimp.org/en/gimp-using-selections.html#gimp-using-selections-moving

Yes, to simply move the border, you can also use the move tool in selection 
mode, without needing any modifer key.

I'd guess this is to make the crop tool's use consistent with the rectangle/ 
ellipse selection tools, where pressing modifier keys _before_ switches the 
normal/add/subtract/intersect mode, so pressing it afterwards was 
still "free".  And, btw, there's nothing lost if you can press shift as late 
as you want, but you win the ability to decide on the final shape until you 
let go of your mouse button.

When doing screen captures, you don't actually get any ppi at all, you just 
get the plain pixels.  The resolution you attach to the image is quite 
arbitrary.  When using it in a book, you might want to scale the image by an 
integer scale with next neighbour "interpolation" though.  IMHO pixelized 
screenshots look better than blurred ones on paper.  But maybe one of the 
actual book writers on this list may tell you more. *hint*

You could turn off antialiasing (extension of the stroke dialog under "line 
style") or use the pencil as "paint tool" there with a 1 pixel brush, these 
two methods look equivalent to me.  You might have noticed that you have full 
color pixels where the path goes straight across a pixel, but less when the 
pixel is only touchedm this is due to the antialiasing that's on by default.

This will give a fully colored, 1-pixel line:
 -
 | x-|---|---|---|---|-x |
 -

This will give a 50% colored, 2-pixel line:
 -
 |   |   |   |   |   |   |
 --x---x--
 |   |   |   |   |   |   |

I hope this helped a bit to understand the problem.

Yes, maybe you should rephrase it, I'd thought that you wanted to know methods 
to have more control than with one of the straightforward methods:
 - Image->Mode->Grayscale (the whole image will be grayscale, you'd have to 
change back to RGB mode to edit with colours again)
 - Colors->Desaturate, which has three predefined modes since GIMP 2.4

If that's not what you want, maybe you should ask again in a different way ;-)

There are no such things as adjustment layers in GIMP, but in one of the 
future versions, much more powerful tools will be available to allow 
non-destructive editing.  You can do pretty much of what's done there though 
in different ways as mentioned on the page that Tim gave.  As to why the BG 
copy 2 layer in your page is b&w, I best quote that page itself:

"the top layer (Background copy) shows where we did a simple 'remove colour' 
and have de-selected the 'eye' so as to hide this layer."

The coloured seem to be effectively desaturated with one of the adjustment 
layers.

Have you tried starting GIMP twice without Pidgin installed?  It could simply 
be that the very first start time takes very long for GIMP because it 
registers/ cashes all the available fonts and then only has to check for 
changes on the second and all subsequent starts.

If both GIMP and libgimp-devel are provided by Mandriva, they should go along 
perfectly fine.  Also, the worst thing that could happen is that things you 
compile with one libgimp don't work together with GIMP in another version.  
As long as you don't recompile GIMP yourself (or any of its runtime

Hi, 

often information about one topic is scattered around the manual, which 
probably can ahrdly be avoided.  As an example, selections are covered in 
articles about their tool preference dialogs, the Select menu, the quickmask, 
a general introduction (gimp-painting.html), gimp-using-selections.html (the 
most asked for on irc) and several others (convert to/from selections).

The articles are well linked between each other, but that's a tedious way of 
finding the relevant piece of information.  Probably it's not a real search 
that's needed but a link to the index, so here it is (to the original 
poster):

http://docs.gimp.org/en/gimp-help-index.html

Another way to search the manual is to use you favourite search engine, google 
for example works with search terms like this:

"site:docs.gimp.org/en/ "

Since the manual is a manual and not a selection of tutorials, you'll find 
mainly documentation about GIMP's functions there, not about how to use them 
for some effect or another.  So even a search function doesn't replace a 
broader search across other web sites.

Luckily for you, there's an official tutorial that might do what you want, 
although it's not in the manual:

registry.gimp.org is the place to generally look for scripts. There will be 
scripts in all languages, also in script-fu/tiny-fu, so as to give you many 
examples.

I don't know much more about scripting, but maybe also 
http://www.gimp.org/tutorials/Basic_Batch/ might be helpful

Did you get that version of GIMP from the "offical" place, i.e. 
gimp-win.sourceforge.net? Do you use any fancy additional display drivers, 
e.g. for addional virtual desktops?

Just two ideas from my old windows times...

Hi!

As http://docs.gimp.org/en/gimp-tool-blend.html clearly says, the blend too is 
the correct one. It even tells you why it doesn't work in your case: Your 
image is in indexed mode: 
http://docs.gimp.org/en/glossary.html#glossary-indexedcolors
Simply convert it to rgb:

Hello!

What is that "turboprint" and how does it work? If it just makes printers 
available via cups, there should be no problem. If it works with Ubuntu 8.04 
but not with 8.10, that would be an Ubuntu problem and the Ubuntu people 
should work on it. Printing through a network (as you seem to want to do) 
works as well or bad with GIMP as with any other application, wireless or by 
cable.

Hi!

If you still have 2.0 or 2.2 there, you probably installed gtk+ separately, 
which could be in a pretty old version by now.  Could you try completely 
uninstalling the old GIMP and the old GTK+ libraries before installing the 
current version of GIMP?

Also other people might be able to help further if that error message mentions 
more details about where exactly the error occurs.

Because most people found the context-menu more useful. MS Paint doesn' have 
this feature. GIMP instead makes use of a wonderful invention, that's much 
mor recent than banging rocks together (like using the mouse): The alphabet,

I haven't worked very much with GAP (Gimp Animation Plugin), it might provide

Try some other movie viewer that can also play the format of your choice.

Hardly.  Somehow the data has to reach the other user's computer to be 
displayed there.  And in that moment you lose control over what's done with 
your data.  The only thing you can do is make it a bit harder for the 
determined and a lot less user friendly for the casual visitor of that web 
page.

First of all, there will be no stable GIMP 2.7, since odd minor version 
numbers are reserved for development releases.

Second, all complaints about some version of GIMP not being available on some 
operating system or distribution should go to the maintainers of that 
distribution, since the only official product released by the GIMP developers 
is the source code.  It's totally up to the distributions to provide 
binaries, in whichever version they see fit.

I hope this helped to answer some questions.

Aiptek tablets are also often sold under other names.  The cheap tablets you 
get at discounters or on ebay are mostly just rebranded Aipteks.

My experiences with one (two years ago now) were really mixed.  If it works, 
fine, but there are chances that it will misbehave in one way or another.

Was that made from a photograph?  I'd say, use Inkscape (yes, that's a 
completely different, but still free, program) and trace the outlines either 
automatically or by hand, and then refine it by hand.  That image was clearly 
done with a vector graphics application.

If you work a lot with texts and if changing the text is the last step in your 
workflow, maybe those steps are easier in Inkscape anyway?  Or you could try 
and write a script that changes the text of all text layers in the same way, 
I think that should be possible at least in theory.

The latest stable is 2.6.5.  Cutting edge versions (more or less snapshots

The number of required changes is actually quite small, iirc.  And 2.6 and its

In most cases there's not much you can do, since scaling the image up doesn't 
increase the amount of available information.  The best programs to improve 
such images do nothing more but good (sometimes surprisingly good) guesses.  
Maybe greycstoration[1] could improve the situation a bit?  And the OCR 
program might work better with increased contrasts, so playing around with 
the levels (or curves) tool could also help.

If you have to work with many pages, my first idea would be to do an automatic 
white balance correction (Colors > Auto > White Balance).  With a little 
luck, it'll pick the "yellow" as white and the pencil as black.  If that 
doesn't work out as you expect, do it manually with the levels tool[1], and 
make use of the three eye droppers (mainly the white one) in the "All 
channels" section.

Getting to know the levels tool (or curves too for even more control) will 
help you with photos and scans anyway.

Daniel

As Martin said, please read the linked documentation. That's not a setting in

Hi Avi, 
each object that has its own boundaries and that can be moved, transformed, 
manipulated individually, _is_ indeed an individual layer. This can indeed be 
cumbersome if you have lots of layers, but the situation will probably 
improve once layer groups etc. are available at some point in the future.

If you feel you don't need to edit or move several layer individually any 
more, you can merge them into one single layer, either by merging down[1] or 
by merging all visible[2] layers.  Note that text layers lose their special 
text layer property when merged with other (even text) layers.

Just a guess:
Did you install GTK+ manually? That shouldn't be necessary any more with GIMP 
2.6.x, but old GTK+ installations might mix badly with the one provided with

Hello Agnes,

which version of GIMP?  The latest stable is 2.6.6.  And which operating 
system?  Where/How did you get GIMP?

Without these basic informations, there's not much anyone can do to help you.  
You might also want to check on the bug tracker at bugzilla.gimp.org if other 
people have experienced the same problem.

I don't know what your image looks like, but if you need a high resolution 
image, sometimes it's easiest to recreate those parts with vector graphics.  
Many fonts have clef symbols that could be used for this purpose.  You might 
even want to use a vector graphics application like inkscape for rubber 
stamps, but that depends on your specific problem, of course.

That means that there is no text layer. jpg files don't know about text, just 
about pixels.  If you saved the image yourself as jpg, you should have 
received a small warning box saying you'll lose all layer information in that 
format.  If someone else gave you the jpg, complain to them :)

If you want to keep all (or nearly all) information about your layers, modes, 
masks, selection and text, you should save the image as "xcf", that's GIMP's 
own format.

I hope this isn't too bad news for you...

You could try to export to either svg (better) or pdf (not quite as good) and 
open the result in Inkscape (another free program).  I sometimes have good 
results with that.  If you need to open it in GIMP, there's not much you can

Hello Dotan,

try pressing the space bar.  Then the mouse should move (or more 
specifically "pan") your view of the image when no mouse button is pressed.  
I think that this is what you want :)  But maybe the navigator in the bottom

Hello Adam,

you could just set the resolution (pixels / whatever) in Image>Print Size and 
set the display units to whatever you need in the little dropdown menu near 
the status bar.  Then the measure tool should always give you the real-world 
size as well.  The only thing you have to do by hand is calculating the 
resolution in the first place.  Some image formats like tiff and png even 
save that setting.

I don't know if there are plugins for this in GIMP, but other imaging 
applications like ImageJ/Fiji can do stuff like this easily. (They offer much 
less creative possibilities though.)

There are lots of plugins in python, but I don't know if it's the best choice 
for file i/o plugins, since if you do a good job, it might be included into 
GIMP by default, and Python isn't installed everywhere.  I'm not sure about 
the speed difference compared to C since reading/writing the file should be 
the bottle neck in most cases.

And/or have a look at other open source projects (with a compatible license!) 
that can handle multi-layer tiff images. (ImageJ, possibly ImageMagick, exiv2 
etc.)

Wouldn't it be the easiest way to set the printer to use CMY only instead of 
CMYK?  Many printer drivers can do this.

A dark blue would still consist of a lot of black since GIMP only knows about 
RGB and only when printing this is converted to a more printer-native 
representation.

For all those tools mentioned in the other posts, check out the "Corrective"

If the mask is white before, that layer should've been completely opaque, so 
filling the selection with black (simply drag&drop from the color patch onto 
the image) should make the layer below shine through.

Of course, if the upper layer doesn't have a mask yet, simply choosing "from 
selection (inverted)" when creating the mask would've been the most 
straightforward way.

Not a real answer to the question, but as soon as (semi-)automatic image 
analysis, registering or measuring areas, distances, etc. are concerned, I'd 
recommend ImageJ (or Fiji) instead.  I use GIMP only for artistic purposes, 
which can include preparing "scientific" images for publication, of course,

Hello,

Too bad that it's on a most-of-the-time-serious mailing list, where it might 
frighten some new, innocent people.

Does this really also happen when you have a file that's never been saved to 
gif, i.e. has never been downgraded to 256 colors?

Hi Jim,

I'd use a 3d modeler/renderer, like Blender.  I haven't used it myself, but it 
should be able to import shapes in many popular 2d vector formats, so creating 
the people in Inkscape first should work.

Cheers,
Daniel

I think that all this kind of stuff might be a lot easier with a program 
dedicated to image analysis. ImageJ/Fiji would be one example, it has lots of 
plugins for almost any analysis need.
While GIMP is a wonderful tool for editing images and being artistically 
creative, it was never meant for image analysis. This doesn't mean what you 
want can't be done, it's just not what GIMP was made for originally.

Just my thoughts,
Daniel

Hi Daniel,

Ha! I discovered ImageJ yesterday, and have written my first batch processing
macro, so great minds think alike, yes? Also decided to include a standard 
reference
card in each picture to aid in equalizing levels among images.

Best regards,
Kinata

I don't know the exact current state of the save/export menu discussion, but 
wasn't the plan that "Save" should always save as xcf? This would mean that 
only xcf files could be overwritten accidentally. And they should be either 
versioned anyway, or they are not irreproducible, at least not as much as a 
camera shot, for example.
Overwriting a real photo cannot be undone without taking that photo again, but 
rearranging layers in a composition is usually much easier.

So maybe your problem will be solved anyway with the next GIMP version :)

2¢ from someone who doesn't spend very much time with GIMP anymore at the 
moment (unfortunately),
Daniel

Re: [Gimp-user] Increasing pixel size

I don't remember such a recommendation, but a radius of 5 seems rather large 
to me because the scaling effects should be on the order of 1-2 pixels only, 
right?

First another question: How satisfied are you with the upscaling result in one 
single step (you can try out several scaling algorithms, of course)?  If you 
think it's ok, it may not be necessary to do more complicated procedures.  And 
how plausible does the 10MP image have to be on the pixel scale?

Finally, if you have the CPU power and necessary memory available, you could 
also try out the "Smart Enlarge" script from the resynthesizer plugin package.  
But be sure to try it out on a small region first, it would be a shame if you 
waited for hours for a result that doesn't look like you want it :)

The other have said already WHY it may display other lengths than you may have 
expected, here's the solution:

In the Preferences window, select "Display" and press the "Calibrate..." 
button there to calibrate GIMP for your display.

This dialog used to show up on the very first GIMP start in earlier times, I 
don't know about the current version though.

HTH,
Daniel

I forgot to mention that one should also uncheck the "Dot for dot" option in 
the view menu.
