Basically when i trim a .tga file to modify art I end up with white edges on some things. Artifacts if that sounds more accurate. I have no idea why it is happening nor how to make it go away.
Example:
If you look at the red bar filling in on the left side of the image you can see what I'm talking about. (it appears like that in game as well so its not just in the screen shot)
I literally took the base image, copied it and chopped it up simply erasing elements I did not need. Afterward I scaled the image as needed for the addon I'm using.
The element I took it from was made the same way but the issue isn't there.
I'm using the latest version of GIMP for editing. Any suggestions as to what I'm doing wrong?
