I attached four similar samples that are fixed with attached patch.

The original sample is G3-compressed, I believe all palletized tiff samples with less than eight bit per pixel and G3 compression do not decode correctly.
Can you provide such samples? (Same compression as 1bpp_with_palette.tif, but with 2bpp and 4bpp.)

I attache palettized 1bpp samples with different compression algos selected.

Can you provide such samples? (Same compression as 1bpp_with_palette.tif, but with 2bpp and 4bpp.)

AFAICT HuffRLE, G3Fax and G4Fax can be only 1bpp.
