CCITTFaxG31DDecodeInputStream - Extended codes have wrong length
----------------------------------------------------------------

                 Key: PDFBOX-1233
                 URL: https://issues.apache.org/jira/browse/PDFBOX-1233
             Project: PDFBox
          Issue Type: Bug
            Reporter: Dave Smith


When dealing with large fax images there are Extended Make Up Codes.
They are added to the tree as ...

buildUpMakeUp(LONG_MAKE_UP, WHITE_LOOKUP_TREE_ROOT);
buildUpMakeUp(LONG_MAKE_UP, BLACK_LOOKUP_TREE_ROOT);

Accept, the length is 0 based not starting at 1792.

The quick hack is to create a new method so the length of the node is correct

 private static void buildUpMakeUpLong(short[] codes,
NonLeafLookupTreeNode root)
   {
       for (int len = 0, c = codes.length; len < c; len++)
       {
           LookupTreeNode leaf = new MakeUpTreeNode((len + 28) * 64);
           addLookupTreeNode(codes[len], root, leaf);
       }
   }

as thus ...

buildUpMakeUpLong(LONG_MAKE_UP, WHITE_LOOKUP_TREE_ROOT);
buildUpMakeUpLong(LONG_MAKE_UP, BLACK_LOOKUP_TREE_ROOT);
