Hi,

I need some help in converting a b/w tiff image into a
jpeg. I had a look on the tiffcp. With a greyscale image
is the conversion no problem, but if I try it with a
b/w image then I get following message:

"JPEGSetupEncode: BitsPerSample 1 not allowed for JPEG" I gess only to change the bitspersample parameter is not enough. Who can tell my in which way I must manipulate the tiff image that the jpeglib process the image? (It can be a quick and dirty solution).

Thanks
Frank
