Hello. It seems I've ran into an issue using Paint.Net to save 24bit Bitmap (BMP) files...
In short, the biSizeImage field of the Bitmap file header is always set to 0!
I am using the latest version, 5.0.3, portable x64 from the github release page.
I have attached an image showing the header files for a bitmap I saved using PDN. The highlighted line has the field I'm talking about.
This doesn't seem to negatively impact anything I use the file for under windows... However, when I sent the file to a friend using some version of Linux (I don't know which one exactly), it would seem that this caused some problems for him and he was unable to use the image.
Saving image using a different editor like MS Paint seems to work fine, and the biSizeImage field gets set correctly as expected...
