When processing big FaxG4 coded TIFF-files I noticed, that the decoder algorithm fails for scanlines of >65k. The reason is an uint16 array to store the runlength encoded data. I changed all that to uint32 and it seems to work now. I wonder why nobody else ever got this problem before. Anyone interested in a patch?
