No, I'm not talking about my hand technique.   

I'm referring to the straight line feature achieved with Shift+LeftClick. The feature works just fine with my mouse. With my tablet pen, however, the dragged line appears when you press Shift, and after "clicking" (pressing the pen to the tablet), the dragged line goes away (as expected) but no line is drawn.

Otherwise, the pen works okay. Even pressure works. Does anyone have a clue?

Hallo,

I need a script for batch mode:

There are files t0.tif and t1.tif (single page tifs) in the current directory.

The script should open these files and put them into a single file as layers
(t0.tif as bottom and t1.tif as top layer).

Then, the script should set "grain merge" to the top layer and add a white
layer mask.

I am somewhat familiar with (scheme)lisp, but I have no knowledge on
script-fu.

Finally, the script should save the file in standard gimp format.

Hi. Im working with sprites and 8 bit backgrounds. I have to convert them to 8 bit (usually irfan view because without Floydd Steinberg dithering reducing colors in gimp makes them really like some ink color spill poor quality, maybe it exists in gimp dunno).





What I also have to do is when  I have an image with 256 color map, I need to add a color to the color map and it has to be first color of the palette (top left corner), it will be used for transparency. Usually BEFORE I convert to 8 bit, I have to make a pixel on the image with the wanted color and then convert the image to 256 colors so that the desired color is included in the palette. Then brush the pixel off the image. This takes a lof of time to do for multiple images.

Is there a way to automate this with script or other way?

For example add a color without messing up the rest of the palette or replacing black color where e.g you will see magenta on an image because you replaced the black in it with magenta.

And then once you add the color to the palette, position it as first. I use it with Color - Map - Rearrange color map but firstly need to add the color to the palette then automate its rearrangement.

Irfanview wont let me have the image with just 255 colors not 256 so that it won''t replace an existing color if I added a 256th color

I would like to know if there is any way to select the same shape of an image in all layers and then cut it and preserve it from changes. I expose my situation:

I want to erase the background behind the character, I am editing a gif file using the ofn-layer-tiles plugin and erasing the background with the color to alpha tool and the eraser. All very well until I realized that I cannot erase blue and white pixels from the background without also erasing them from the character (eyes and clothes). Erasing with the rubber layer by layer has been difficult for me and I was wondering if there is a way to "protect" the character by removing it from the selection or cutting it, because it is a static image, I share the progress that I have of the image now and also the original image:https://i.imgur.com/6pX6Z90.gif and original https://i.imgur.com/gDRIbQX.mp4
I hope I have been clear and can help me

Hey my lovelies I am trying to use to the filters that come with gimp. I was wondering is there anyway I could make the preview larger for the plugins (like Iwarp). What I am working on now is way to small for me to see I have resized the window but that didn't help. I wear glasses and it still is to small for me to see. Is there any way I can fix this? Thanks in advance

Esteemed Colleagues:

Readers of this forum know that I recently built gimp 2.10
from source, and it was a nightmare, but I did it.

Now -- apparently in search of suffering, for there can be
no other reason for trying to do this -- I am trying to build
gimp 2.10 from source again, for another operating system
that shares the same hardware (my laptop is a multiboot
machine, I have several operating systems installed on it).

Because gimp 2.10 has many dependencies that are newer
than the versions available thru my package manager -- or,
in some cases, not available at all thru my package manager
-- I have had to build those dependencies from source. Only
one unbuilt dependency now remains on this operating system,
gegl.

I cannot build gegl on this operating system.  That, of course,
is surely not true, what I mean to say is that I have not figured
out how to build gegl on this operating system.  I turn to you,
esteemed colleagues, for help once again.  This is the error
message that I get, time and time again, no matter what -f
arguments I have given to the compiler (and I have tried
many):


    operations/external/exr-load.so.p/exr-load.cpp.o: In function import_exr(_GeglBuffer*, char const*, int)':
    /usr/local/src/gegl-0.4.26/build/../operations/external/exr-load.cpp:506: undefined reference to Imf_2_1::Chromaticities::Chromaticities(Imath_2_2::Vec2<float> const&, Imath_2_2::Vec2<float> const&, Imath_2_2::Vec2<float> const&, Imath_2_2::Vec2<float> const&)'


This is at operation [481/750] of the ninja build.

Most likely this is a missing constructor that should have been
created from a template, but which the c++ compiler is failing
to create.  But templates have been around for a long time
(31 years, in fact -- I remember when Bjarne Stroustrup
announced them in the Journal of Object-Oriented Programming;
but I digress) and I am using gcc 9.2.0.  Surely by gcc 9.2.0
the g++ compiler has managed to get templates right.  So
what is going on?  I suppose I could build clang from scratch
and then try to build gegl with clang++, but I am certain that
this is not a compiler problem.  And yet, this same version
of gegl has been successfully built before.  So why can I not
build it on this operating system?  What do I have to do?
As always, I thank you in advance for any and all replies.

Testing a new script. If you look at this picture long enough, you will perceive a full shape in the middle (middle "deeper" than the rest).

   

I am new to GIMP. Anytime I open a dock like Color Balance, Exposure or Curves, the moment I make edits with it and click "OK", the dock just disappears. I don't know how to recall it, especially when I want to adjust something I have done.  I found a place to click under Windows called "Recently Closed Docks" but it just never works. Is anyone else having that problem please? I use a Macbook.

Hi
I've just switched to a new laptop, and I'm finding that I can't print the whole image. Approximately 14% of the width and height show as blank on the image preview - blank strips to the right and bottom. I can't find any reason for this! Anyone know what is causing it?

This must be something extremely basic, but I can't figure it out.
I have a selection which I am trying to delete. The layer has an alpha channel, but I want it to stay true to the selection (that is, EVERYTHING in the selection is deleted, and EVERYTHING outside the selection is maintained). When I select it and delete, this happens:

this

goes to this


It looks like some kind of antialiasing or texture filter, how do I disable it? As in, the selection needs to be 100% cleared to alpha, and the pixels outside the selection need to be untouched.
