Hi Tadziu, > (But it should have given you a "Not a raw PPM" error, because raw > PBMs have a magic number of "P4" instead of "P6").
(Given the OP said bitmaps originally but passed the P6 test I assumed he'd done something like `convert foo.pbm ppm:' which left the maxval at 1.) I agree, sticking with the bitmap is better given you've made a P4 version available. :-) Cheers, Ralph.
