I have difficulty loading fff files using FreeImage. I thought it might be my code but the "Multiple Image Resizer.NET" program that also uses FreeImage has the same issue with these files.
They are correctly identified as RAW files but get no further as the C++ function FreeImage_LoadFromHandle returns 0. It works fine with other RAW files such as nef and cr2.
I can supply a sample upon request, but they are quite large 234181 bytes.
