-------------------------------------------------------------------
The decoder that we use (which is an older version of a Sun decoder) doesn't
recover from corrupt data, but it should:
http://www.fileformat.info/mirror/egff/ch09_05.htm
{quote}
If corruption of the data transmission occurs, only K-1 scan lines of data will
be lost. The decoder will be able to resync the decoding at the next available
EOL code.
{quote}
The code at the exception does not do that, it just fails.
I looked around for other projects using the same decoder, and found this one
in a probably defunct project:
https://java.net/projects/pdf-renderer/sources/svn/content/trunk/src/com/sun/pdfview/decode/CCITTFaxDecoder.java?rev=140
That one does decode the file, but is LGPL licensed, so we can't use it. It has
numerous changes compared to our version.
