I'm using gm for heavy work with tiff-files. Unfortunately I have to use
ImageMagick to convert to 4 bit grayscale tifs. Use the attached testfile for
reference:

% gm convert -compress LZW testpicture.tif -colors 16 -colorspace GRAY -depth 4 
testpicture_4bit_gm.tif
% convert -compress LZW testpicture.tif -colors 16 -colorspace GRAY -depth 4 
testpicture_4bit_im.tif
% identify testpicture*.tif
testpicture_4bit_gm.tif TIFF 256x256 256x256+0+0 8-bit sRGB 18.7KB 0.000u 
0:00.000
testpicture_4bit_im.tif[1] TIFF 256x256 256x256+0+0 4-bit Grayscale Gray 8.44KB 
0.000u 0:00.000
testpicture.tif[2] TIFF 256x256 256x256+0+0 8-bit Grayscale Gray 8.08KB 0.000u 
0:00.000

-> The gm created image is 8 bit sRGB while ImageMagich creates the 4 bit
grayscale as requested...

I tried to report the bug upstream but find the sourcefourge.net webinterface
unusable.

Thanks,
Markus
