component precision upscaling isn't correct in opj_decompress #458

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
component precision upscaling is done by a simple shift.
This leads to undesirable results. e.g. 1 bit bit rescaling to 8 bits gets 0U 
=> 0U, 1U => 128U. instead of 1U => 255U.
