Make sure you have access to the thing you tried to change. You may want to save your images and restart GIMP to be on the safe side. but do not expect an immediate fix, there are several outstanding bug reports for the dds format. Report this as a bug to the Gimp developers. (05-04-2023, 07:46 AM)y2keeth Wrote: The dying plug-in may have messed up GIMP's internal state.

I32 DDSFileDecoder::BindDDSFile(const I8 *name)įread(&header, sizeof(header), 1, dds_file) A few times I would take a corrupt dds, convert to a few different formats, maybe perform a light Gaussian blur, change it back to a dds and then it worked great with no corruption. I compared a dds file that works versus a dds file that is corrupt and the headers are identical. On some DDS files it works great, on others some or much of the mipmaps are corrupt. I only use DXT1, DXT3 or DXT5 file formats. I wrote a simple program that loads compressed and mipmapped DDS files in OpenGL with the "glCompressedTexImage2D" function.
