[Gimp-user] How to make a set of curves

[Tőkés Ábel]

Hello,

I would like to make a set of smooth curves that are near to each other 
and all are
just slightly different from the neighboring ones. Two examples of what 
I am thinking of
are in the banner of these web pages:
http://www.sopra-sa.com/index.php
http://www.advancedmetrologysystems.com/products.php

Is there a plugin for such effect? How would you do it in Gimp?

Thanks:
Abel

Re: [Gimp-user] How to make a set of curves

[Tőkés Ábel]

Hi,

I have found a script that seems to be written to the purpose I want:
http://registry.gimp.org/node/22016

I saved in in my C:\Documents and Settings\Ábel\.gimp-2.6\scripts\ 
directory,
and called Filters, Script-Fu, Refresh Scripts. I got an error message:
Error while loading C:\Documents and 
Settings\Ábel\.gimp-2.6\scripts\script-fu-shapes_0.scm:

Error: unable to open "C:\\Documents and 
Settings\\Ábel\\.gimp-2.6\\scripts\\script-fu-shapes_0.scm"

What am I missing? I am working on Windows XP Professional, and Gimp 2.6.7.

Thanks:
Abel

Re: [Gimp-user] How to make a set of curves

[Tőkés Ábel]

Solved. I copied the script to:
C:\Program Files\GIMP-2.0\share\gimp\2.0\scripts

I think the problem was the Á in the other path.
Windows doesn't allow me to change that folder name, unfortunately,
so I will have to use the above directory.

Sorry for bothering.

Hi!

I make a lot of word documents packed with photos and other kinds of 
bitmap pictures in them,
and I usually make pdf of them as a result. This is part of my work.

 From the behavior of these documents I got to the conclusion that Word 
stores all bitmap pictures
in a jpg format. This is independent from the source of the picture 
(whether it was inserted as a picture
file or just pasted from the clipboard.) So, every time I save the 
document, more and more jpeg errors
are produced in all pictures. This effect can be reduced if the 
resolution of the images is kept high
(eg. 200 dpi), but this makes the filesize big and is not an option for 
all kinds of pictures.
This effect is mostly annoying in case of pictures thats natural format 
would be png: that include
just a few colors, like drawings and screenshots. These pictures are 
made ugly and make the filesize
irrationally big.

Moreover, when I print to pdf, all the pictures are made 96 dpi (just a 
guess, it seems to be optimized for
screen), and full of jpeg noise. So, the pdf-s are even more ugly than 
the doc. I don't know any options
that could be set in pdf creation.

I think that a good pdf printer should have some settings for image 
compression, and office should have
more options. I only know of the compression rate, where you have three 
options: leave it big,
set to 200 dpi (for prinit), or set to 96 dpi (screen). I think this is 
quite poor. I know some about word,
but there is much more that I don't know, so there may be more advanced 
settings. But I doubt.

So, if anyone knows an answer, please let us know!

You are right. I wasn't able to reproduce jpeg failures with Word.
I thought that it came from image compression,
but I wasn't able to make noise by it either. I will have to find out
where noisy images in my docs come from. It seems that Word is
more clever that I supposed.

For me it seems that the problem is with the pdf printer. I tried Adobe 
Elements and
CutePDF. Both added jpeg noise. Surprisingly, CutePDF gave somewhat 
better results,
though it was free and we paid for Elements, and I prefer Elements in 
most cases.

I am afraid we are becoming more and more offtopic, as this is obviously 
a pdf printer issue,
and probably office issue, but not Gimp issue.

Re: [Gimp-user] Selected elliptical area always inside a rectangle

[Tőkés Ábel]

Hi!
I would do it this way:
-Add alpha channel (Layer, Transparency, Add Alpha Channel)
-Apply selection
-Invert selection (Select, Invert or Ctrl+I)
-Delete the area selected
-Autocrop image (Image, Autocrop Image)
-Save in png format (that saves transparency.)
-in word: instert picture from file

Alternatively, you can skip adding alpha channel, if the background color
is white, the area outside the ellipse will be white, then you can save 
it in jpeg
without problem, or copy the whole picture to the clipboard and paste 
into word.

Hi,

One way to make an octagon selection in 2 minutes:
1. Use rectangle select tool, set to fixed size and enter a size with 
equal sides to make square. Select a square.
2. Use rotate tool, set the object of transformation to Selection and 
rotate it by 45 degrees.
3. Use the rectangle tool with the same fixed size, set the mode to 
Intersect with the current selection (Ctrl+Shift)
4. Select the rectangle in the same position as the previous

Once you have the selection, you can stroke it or fill it with anything 
you want.

Hi,
Most probably you don't have an alpha channel on that layer. To add an 
alpha channel, right-click on the layer name in the Layers Dialog and 
choose Add alpha channel.

Hi,

You have to add alpha channel from the image menubar through Layer → 
Transparency → Add alpha Channel.
http://docs.gimp.org/2.6/en/gimp-layer-alpha-add.html

With an alpha channel, the default operation of eraser is deleting to 
transparency.
However, if you want to turn white to transparency, you'd better use 
Colors → Color to alpha.

Hi,

I think a possible reason can be: The resolution of your monitor is 
better than the resolution set in Scale Image window. I tried and 
experienced the same thing as you, and I got a 5x7 cm square with X and 
Y resolution 89 pixels/in on my monitor.

The reason of this is that at 100% zoom level, gimp indicates each pixel 
of the picture on one pixel of the monitor, independently from 
resolution. Resolution and image size in pixels determine together the 
image size in cm. The meaning of image size of 5x7 cm for eg. 72 
pixels/in when your monitor has a different resolution is that if you 
print your image with the set resolution, you will get the an 5x7 cm 
image. (72 pixel/in printed is quite poor resolution.)

Hi, I don't know how to make a nice gel effect, but if I were you, I 
would experiment with methods used in creating metallic effects to make 
a shiny, 3d looking surface. I have once followed a good tut that I 
think can be useful for your purpose too:
http://penguinpetes.com/b2evo/index.php?title=gimp_tutorial_metallic_text&more=1&c=1&tb=1&pb=1

Of course, you will have to change this workflow to make a gel-like 
effect. I suppose that adding some transparency to your layer and using 
proper colors can solve this.

Actually, this is possible. Change Mode to Color erase. If you have an 
alpha channel on the layer, it will erase to transparency.

Hi,

When you paste a new picture into your canvas, it becomes not a real 
layer, but a floating selection. If you click with a selection tool 
anywhere on your current layer, outside the floating selection, the 
floating selection becomes anchored down on the layer. Another 
possibility when you have the floating selection is to go to layers 
dialog, and click on new layer button (the white page). This will turn 
your floating selection to a layer, and it will be visible anywhere 
inside the canvas.

Re: [Gimp-user] Merge linked layers

I imagine there can be a non-trivial problem with the concept if the 
linked layers are not all neighbors:
if there is at least one layer that is not one of the linked, but 
between those. In this case, where would the

merged layer be: above or below the middle one?

I've never found a way. I just use the "Merge Visible Layers" action
instead. Click on the visibility icon next to each layer to make only
the linked ones visible, then use "Merge Visible Layers". Same result,
but a few extra clicks.

Re: [Gimp-user] Scaling / rotating images and focus

[Tőkés Ábel]

Øyvind have already answered your question:

"It indeed is, and this should eventually solve itself as GEGL is more
properly integrated with the layer stack of GIMP and what is shown is
no longer a preview but the actual result. For now the preview is a
hack that provides better visual feedback than just a bounding box or
a wireframe grid.

/Øyvind K."

This means that your request will be automatically solved in the future release.
You don't have much chance that anyone will spend his/her time by writing a 
temporary solution.

How does one go about requesting this as a feature enhancement?

To include this in Gimp would vastly improve usability in this regard, 
as well as making logical (and practical) sense.

the opacity is made less.


But that's besides the point.

1.  If I've set the opacity of the layer, then the opacity of that 
layer should remain as is when I scale / rotate.
2.  When I scale / rotate, the layer's position in the stack should 
remain in its place, rather than suddenly appear at the top of every 
layer when being rotated / scaled.


Surely, this is a reasonable request?

Again, I've found how the focus of the image being rotated / scaled 
interferes with the rest of the working area.  For example, if I 
set a particular layer's opacity to 20% and the layer is at the 
bottom of all other layers, why, then, does the opacity become 100% 
and the layer suddenly appear on top of all other layers?


This makes it very difficult to work efficiently.

Is there a way to fix this / work around it?


The Scale and Rotate tools have an opacity slider for the preview...

I would use Select by Color tool, and adjust threshold in the Tool 
Options Menu.

[Gimp-user] Can't read file header

[Tőkés Ábel]

Dear Folks!

My problem is not strictly related to Gimp, but I hope that Gimp can 
help me solve it and
I am sure that there are a lot of clever people on this list who can 
help me understand what is happening here.

I have appr. 100 pictures selected from the thousands taken of my 
wedding. I would like to send them to a
printer company, but the software they give cannot use them because of 
the failure that prevents IrfanView
from opening them too. The funny is that all the other picture viewers 
can open these pictures, including
Gimp.

I tried to open a picture with gimp, then save it in different formats, 
but they behave the same: IrfanView cannot open them.
I tried jpg with and without exif data, png, tif and xcf. The funny is 
that if I try to open it from inside gimp by file>open or
by drag-and-drop, it opens it without problem, but if I try to open it 
from the file manager, it gives an error message:
Opening 'C:\Documents and Settings\Ábel\My Documents\My 
Pictures\2009-04-25 Esküvo\p0023.jpg' failed: Could not open 
'C:\Documents and Settings\Ábel\My Documents\My Pictures\2009-04-25 
Esküvo\p0023.jpg' for reading: No such file or directory

One of the images is here:
https://picasaweb.google.com/lh/photo/QVOculUehRDqAywlBYIwwQ?feat=directlink

What is the problem with these pics and how can I eliminate it?

Thanks:
Abel

Re: [Gimp-user] Can't read file header - solved

[Tőkés Ábel]

Hi all,

Thank you for your guesses and intention to help.
The cause of the failure is the same banal one that I ran into a couple 
of years ago - the name of the directory.

I am so misfortunate that my user account was created originally with 
the hungarian special character Á.
Moreover, this folder included the characters ü and ő. For God knows 
why, windoze allows creating directories
using these, however a lot of applications cannot handle them properly. 
This is the case now.

I just simply copied the pictures to a folder that's path uses only 
standard ascii characters - and it works!
