Thanks Joerg and Jim !
If uncompressed B&W is the format, grab ImageMagick and install. Then do:
convert filename.jpg myfile.xbm
The XBM image format (X bitmap format) is exactly a C source file:
I tried xbm under Gimp but it produces an array of 16bit integers
rather than bytes. I will try producing the xbm file using ImageMagik
as you suggest, maybe it produces an array of bytes, worth a look !
If not, well nevermind, you and others have given me plenty enough
information and code samples to sort me out "manually" so to speak.
Thanks again everyone for all the help, I must confess I am a little
overwhelmed by so many useful replies, I am lucky ! :-D
