2001.02.05 09:11 "converting bilevel to greyscale", by Juergen Braukmann

Hi all,

I assume this is a FAQ, but I didn't yet find a TIFF FAQ, nor any pointers in the archive.

I want to convert a bilevel Tiff Bitmap to a 256 Greyscale Bitmap. How can it be done?? I looked at rgb2ycbcr since it came clothest from checking the manpage, but I failed with "No space for raster buffer".

The used libtiff version 3.4.final

Any pointers??
