Description

I have multiple tiff images that are causing an "ImageReadException: Decompression error". All are Group 3 (T.4) encoded with T4Options tag value 4 (zero fill to byte). Other Group 3 images without T4Options 4 work fine.

Stepping through Imaging 1.0 RC7, the hasFill boolean is being set properly to true. The exception is thrown at the bottom of method HuffmanTree.java decode(bitStream). Nothing is passed to this method indicating zero fill or not. I will attach a test image that reproduces the issue. The stack trace:
