#18 NullPointerException when opening PDF comic with CCITT image

[Thomas Aglassinger]

When opening a PDF comic with images in CCITT fax
encoding, a NullPointerException ocurs.

This is a known issue in PDFBox. See
<http://sourceforge.net/forum/forum.php?thread_id=1259059&forum_id=267205>
for the current status.

An example PDF file to reproduce this can be downloaded
from
<http://archives2.bungie.org/manuals/Marathon_2_Manual.pdf>.
This is the manual to Marathon 2, which contains some
black and white scetches using CCITT.

Reproduced with: jomic = 0.9.13, java = 1.4.2_05,
platform = Mac OS X-10.3.9-ppc

This has apparently been fixed a while ago, see PDFBox patch 1235260 (Add CCITT Fax Images): <https://sourceforge.net/tracker/index.php?func=detail&aid=1235260&group_id=78314&atid=552834>

Upgrading to PDFBox 0.73 did the trick for Jomic 0.26, maybe earlier versions already worked too.
