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.

Hi all,

After being stuck for a while now i decided to join this forum. I am creating a logo but i cannot figure out how to create a hue like outline like in the following logo.

Can you guys help me out?

kind regards,

Hello!

I've installed Gimp 2.10.20 in my Ubuntu 20.04.1 LTS using Flatpak. I've written a Script-Fu which processes a given image by scaling, and applying threshold and oilify filter. The script runs successfully but in the end, I get this weird message (see attached image).

gimp-2.10: GEGL-WARNING: (../gegl/buffer/gegl-tile-handler-cache.c:1076):gegl_tile_cache_destroy: runtime check failed: (g_queue_is_empty (&cache_queue))
EEEEeEeek! 2 GeglBuffers leaked
To debug GeglBuffer leaks, set the environment variable GEGL_DEBUG to "buffer-alloc"


I've found out that this line is responsible for the warning message (I commented out everything in the code except this line, and I still get the error).

When I
1. Flip my image horizontally and save as jpeg or png in GIMP 2.10
2. Save it on my Android 10.5 phone
3. Try to use it in the Webex app (beta background feature)
The preview shows it in the desired orientation but when I apply it as a background pic it reverses the flip.

I am assuming there is some attribute in both jpeg and png that is picked up when previewed in Webex but ignored when the pic is applied.

1. Is my assumption right?
2. If so: how dow I get GIMP to "truly" flip instead of using the attribute?
