FS#3178 - TIFF LZW/PackBits compression
LZW and PackBits compressed images are not read correctly.
They differ slighty from the ground truth (provided in unsigned char in a header). note that the differ exactly in the same magnitude.
when i write the read image in PNG it look +/- right. so there must be some systematic error. I suspect it to be the TIFFReadRGBAImageOriented function

Reason for closing: Not a bug
Additional comments about closing: the problem was the test. i compared it with the ground truth that didn't have any alpha.
