I just recently updated from a previous version of gimp to 2.10 and have about 16 minutes ago found that the Brightness and contrast options show a accurate preview of what "should" happen but instead it does nothing.
I also just tried to use "levels" to try and accomplish the same effect but that also did the same thing (nothing)

This is a new image that has RGB color ect, but ill add more information here if i need to clarify things.

On GIMP 2.8 on my mac, I can't find the brush "Size".

I attached a picture of my display. It shows "Spacing", but not "Size".

Where can I find it? please help.

   

Hello guys, 



I have just solved my probleme of saving file (see thread file-png-save-defaults) by replacing one part of the code for another that I found on internet. 

I would like to understand why the one I use at fist didn't work. 



That is a problem of string building. Below in the code, two different way to build a string (which is eventually insert in the save file-png-save-defaults function).

The option number one is working. The option number 2 is not. Do you have any idea why ?

Hello,

I've been trying to add a shadow to the attached image - I want the shadow in front of the image with a light source being behind the subject to the left.

I just can't figure it out. I've tried Drop Shadow & perspective shadow but can't find any way to add it to the front. I've also tried Gmic and Layers Effect.

I'd really appreciate any advice as it's slowly driving me mad this morning! 

Thank you for any help and advice,
Lisa

I've been using 2.8 to do texture work for a very long time without any major issues, but after updating to 2.10 and proceeding to use it in the exact same way the program keeps abruptly closing with no warning, no errors, and no chance to save my work.  It seemed to happen most frequently when working with multiple windows open, but it just now happened twice in a row while working on a single image.  This basically renders GIMP totally unusable, as I can't keep throwing work away every time the program dies- the odds of a crash or completing a texture without issue are about 50/50, and it's very easy to forget to save when focusing on the work I'm doing. 

I use a Huion drawing tablet and am usually using it to draw when the crash happens; it doesn't appear to happen when the program is inactive, it's always when I'm in the middle of something.  I need pressure sensitivity and never work with just a mouse alone, so I can't say whether it happens as frequently then.

I'm not able to go back to 2.8 since I now have many files saved in the new format...  Where can I begin troubleshooting this?  Are there any crash dumps or logs I can find?  I'm on Windows 10x64 and using the latest drivers for all my system. I tried uninstalling and then reinstalling GIMP over again, but the issue persists.

Hello GIMP forum, 

I hope someone would be so kind and help me with this challenge. 

I will like to combine an image of a soccer player and a 3D render image I have created. So far I have been able to put the two pictures together.. But I need the final touch to make it look more 'real' or 'life like:

Do any of you have some suggestions of what I can do? I have put the different files that I am using into a dropbox folder: 
https://www.dropbox.com/sh/xkq2fek0sluk4...y05Va?dl=0


Please feel free to guide and show me what is possible - that would be a great help for me. 


Thank you, 
Christopher

Hi, my first message in here   don't know much about scripts and all, but I really wanted this to work...

So I installed Gimp 2.10 and quickly found out that many scripts would generate errors.
Sadly one of my favorite (Vignette script) from:
Dom_C at "http://registry.gimp.org/node/17267" would not work anymore.

The first error was: Error: eval: unbound variable: NORMAL
Quit Gimp
So I open the script file "vignette.scm" for me it was in:
"C:\Users\username\AppData\Roaming\GIMP\2.10\scripts\"
I search for the word "NORMAL" and replaced it with a zero "0"

Re-started Gimp and tried again.
Then second error was: Error: Procedure execution of plug-in-gauss-iir failed...
Quit Gimp
Again in the script file "vignette.scm":
I search for the word "plug-in-gauss-iir" at this point I did many trial and error to finally figure that it was with the radius so I searched for "radius" and finally found this line:
"(theRadius (* inRadius (/ (max theWidth theHeight) 25) ) )"
I replaced it with a different value like this:
"(theRadius (* inRadius (/ (max theWidth theHeight) 400) ) )"

Tried it with images of "RGB color 8-bit gamma integer" and
"RGB color 32-bit linear floating point 6000x4000"
and it worked for me
I hope, for those who like this old script, this will help..
Have a nice day.

Q1. I know how to fade-in or fade-out for paint brush. What I don't know is how to do the both fade-in and fade-out together. Is it even possible?

Q2. I'm creating a new dynamic for fade parameter. Color and Angle works for fade-in perfectly, but color and angle doesn't work for fade-out. Strange. Am I wrong?

   
I'm testing "color erase" mode for paint tool. Background color is cyan. I painted blue color on it in the "color erase" mode. Then the green color came out. It is fine.

Now background color is yellow. I painted red color on it in the "color erase" mode. I'm expecting green color for the result, but nothing happens. What's wrong with this approach?
