Fbm is a very nice package for image manipulation and conversion. We
needed a way to convert our own homegrown format into different standard
image formats.
The patch that is included at the end of this message will extend the routine
'raw2fbm' of the 'fbm'-package with a new option that allows to skip
a declared amount of "header-bytes" at the beginning of the raw file.
Maybe, that this small improvement will be useful to others...
For more information on fbm see the FAQ list of this newsgroup.
