When exporting to png there is an option to save color values from transparent pixels.  It is not the default.  I am still a newbie with transparent pixels.

I am tracing objects with the intent of later adding them to another image.  First I trace with free select and then I copy and paste the object to a transparent layer.  Then I export to a png and I get the option to save color values from transparent pixels.  I don't know whether or not to select this option.

When I zoom in on the pasted object on the transparent layer I see along the edge of the tracing what appears to be partially transparent pixels.  If I opt to save color values from transparent pixels will the object blend better when I add the png file to another image?

Dear all,

I've been searching this forum for a way to get rid of the white line in the middle of the attached photo which is the result of stitching 2 scans together.
As I'm not entirely sure of the right terminology (I've used e.g. removal of crack/border/line) I wasn't able to figure it out yet. That's why I posted it in the general section.

Is there an option in GIMP that allows you to remove or enhance it in such a a way that it isn't visible anymore? 

Thank you in advance.

Sander

Make palette with the color mixer, take colors from the screen, make color schemes, etc... :  https://www.cyotek.com/cyotek-palette-editor

Hello,

 I'll would like to know how change color selection in the channel tab.

By default dark is active selection and light grey is off selection non active.

I ll find this way disturbing.

Ill prefer to make active >light or color and inactive> dark.

How I'll could change this setting to have that I ll want.

Thanks by advance for your help and tips.

Best regards.

Hello, it's been a long time since I last perused the forums. I've been greatly enjoying 2.10, I can't wait to try the next release!
I have not encountered the following problem while running 2.10 on Gimp Linux AppImage. I have had some weird bugs associated with GMIC on Linux with GIMP 2.10, but that's a different issue. This seems to occur solely with 2.10 using default features on my Win11 install.

Black "stains" will suddenly appear, usually as a result of a default filter being applied or by messing about with layer modes. Even if I undo the effect/mode change, the black spotting will not necessarily disappear, or the distortion will take on a different form. I'll attach a couple screenshots to demonstrate:



The left example was actually spurred by a simple gaussian blur with a a radius/amplitude of <10, which makes no sense to me.
I have not been able to reliably repeat these distortions, so I cannot say what the exact trigger is. It's not from something obvious like blowing out pixels with a Hard Mix mode-- and again, this doesn't happen on my Linux install of GIMP 2.10, just the Win11 one, and effects can persist even after an undo. The only sure fix seems to be deleting the "corrupted" layer(s).  I can provide a link to above xcf though its 380mb ziipped. Does anyone know what might be wrong or if I've done something to cause this?

Is there any method to use the recently released dev version GIMP 2.99.12 in Ubuntu 22.04?

Something like an AppImage? Thanks.

How do I convert a palette, of multiple colors, directly to a gradient? I know I did this a long time ago...but now I can't get it for the life of me. I can do the "segment split"...but I want a palette of, say 5 colors, to be imputed and spaced evenly.

GIMP Version 2.10.32
I have a JPG file of an image of a hand-written signature.
The line is too wide.
How can I make the line narrower?
I've attached part of the JPG file.
   

Hello....I am using Mac Catalina 10.15.7

After I edit a photo using Amazon photos online editor, I can no longer edit photos via GIMP 2.10.32.
Once I download a photo that has already been edited in Amazon, regardless of the photo type, Gimp will load the photo but it will not be editable and I basically have to shut down the program. Saving the photo with a new name or as a different file type makes no difference as if the photo was locked.

The picture either opens with the Clone pointer without the circle displaying the size of the clone and changing the clone size does nothing and the you have to close down the program. The alternative is that the program opens and the picture is not displayed but rather a blank background ( image attached)

Any thoughts or ideas is appreciated

thanks
rick

Hello, the attached capture is an expansion at the pixel level, I would like to change all the pixels with that different hues of beige in the complete image to grey #999999 for example. 

This is from an old and aged image of a book dust jacket, I am trying to erase the "paper" background in the image and then put a layer with a clean "paper", I made a bucket fill of that background paper with #999999 with the intention of at the end to change that color for transparency, but as you can see in the image are still a lot of pixels with different hues of beige left, so, is there any method/s to substitute all that different beige-ish pixels, or erase them, or make them transparent? 

Thank you.
