I have two identically-sized .png's that both contain (only) a large, solid circle.

In one image the circle has a few pixels around the perimeter that fade to transparent (barely noticeable at first, and gradually fading more until the last pixels at the very edge of the circle are almost completely transparent). 

The other image contains only completely solid pixels (within the circle), and completely empty pixels (outside the perimeter).

Is there a way to apply (just) the alpha values from the first image, to the second one? (so the second one also fades gradually to transparent around the perimeter)

Thanks for any help!

Hi

Is there a way in GIMP or a plugin, script, ... to extract all the black squares from this image automatically to separate PNG files?
So I need a folder that has all squares (no matter if the square is empty or not) saved as 1.png, 2.png, 3.png, ... from this image
I need step by step instructions because I'm a beginner

My GIMP file is here:

https://www.mediafire.com/view/zh9zdytld...t.xcf/file

Image preview:

Why can't we attach a file here on the forum (file is under 100kb in zip file)?
Error: Request Entity Too Large

The requested resource does not allow request data with POST requests, or the amount of data provided in the request exceeds the capacity limit.

I don't know what setting I changed.  Now when I merge visible layers some of which extend beyond the canvas size Gimp crops the image to the canvas size.  I don't want to crop.  

Thoughts? Suggestions?

Windows 10, Gimp 2.10.34

Version: GIMP 2.10.36

   

I have a simple image      2x2 RGB(54,58,83) and the color picker converts this to CIE LCH
L = 24.9% C =  16.2% H =  282.3°


if I do Colors → Components → Decompose [uncheck 'Decompose to layers' ] and look at the L C H images the RGB% are: 
L = 24.7% C = 8.2% H = 78.4% (78.4 * 3.6 = 282.24°)



L and H are pretty close, however C is 50% out - What am I doing wrong or misunderstanding or is this a bug?


and help or workaround much appreciated


   
   
   

I need to export a PNG with 16 bit depth of the final image. The lowest I can get is 24 bit depth when exporting with 8bpc depth. I somehow managed to export a 16 bit PNG earlier but I can't remember how I did this. I've tried looking for an answer online but couldn't find one. I am using greyscale image mode with 16bit integer precision. Does anyone know how to export in 16 bit depth - maybe some kind of plugin is needed?

Hey, I am brand new to using GIMP.

I'm following a tutorial from the gimp website on how to make a fake 3d text image, and i'm getting stuck at the bump mapping. it is not "mapping" to allow me to see my text as 3d. 

I think i'm applying it to the correct layer 

Thanks!

I'm using a laser engraver that can cut a variety of material. When using Adobe Illustrator, "cutting mode" happens when line thickness is set to 0.001" (one thousandths of an inch). Can GIMP set line thickness to 0.001"?

Vielen Dank!

That was a forum I had used to go time to time, I subscribed something like 15 years ago, a week or 2 ago I tried to go but it was unreachable and today I came across this ➤ https://petapixel.com/2023/10/17/the-pho...ting-down/

Added export as PDF with option layer as page

At the usual place (as Ofnuts would say )

Hi
I'm using GIMP 2.10.36 on win 10. In the past I've exported pdf files OK, but the file I'm working on at the moment the rhs of the layer(s) is truncated, or, rather, seems to be covered over by a rectangle of background colour - the overall width of the document seems to be about what I expected.
Any idea what could be happening here?

Gary
I've investigated a bit and it seems that the layers are not truncated but there is something in the generated file that prevents Microsoft Edge -- my pdf reader -- from rendering the file correctly. It first reports that there is a problem with the file, and doesn't open it. It is when I try to load the file into edge a second time that it appears to have the rhs of the document 'truncated!. However, I've tried to open the file with irfanview and there it does load OK, but of course irfanview is not a good option for viewing pdf files. So I would like to know what gimp is putting (or not putting) into the file that renders it incompatible with MS edge.

I have generated pdfs from gimp before which do not exhibit this problem, and as far as I can think I've produced this one in the same way.
Any suggestions welcome as I spent quite a bit of time producing these files and have several more to do, and I really don't want this happening.
