My experience is that the tiff2dib.c utility included with libtiff is quite broken. If I recall correctly, it has several bugs and even calculates the number of bytes per pixel wrong, so that it couldn't possibly work as-is except perhaps for images with exactly 8 bits per pixel. (I could be wrong though.) BITMAPINFOHEADER (not BITMAPHEADERINFO) is a standard structure in Windows programming - http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmeother/graphcnt_1m0j.asp I don't know enough about DJGPP to tell you what you'd need to do. In VC++ 6.0, it should be available if you include <windows.h>. -- Jason Summers
