JBIG2 decompression errors #4247

Closed bsl-zcs closed 10 years ago

Visual garbage is produced on several files containing image masks in JBIG2 format. Other PDF viewers are displaying that files correctly. After the recompression of the same masks in another 1bpp format, pdf.js decodes them right too.
