---------------------------------------
Summary: Immediate generic refinement region with no reference not
displayed
Key: PDFBOX-6160
URL: https://issues.apache.org/jira/browse/PDFBOX-6160
Project: PDFBox
Issue Type: Sub-task
Components: JBIG2
Affects Versions: 3.0.4 JBIG2
Reporter: Tilman Hausherr
Assignee: Tilman Hausherr
Fix For: 3.0.5 JBIG2
The attached file has an immediate refinement region segment that refers to no
other segments. This previously brought an NPE and I changed it to an
InvalidHeaderValueException. However it turns out that this is legit, and
described on page 71: "In this case, the region segment is acting as a
refinement of part of the page buffer." So we have to pass the page buffer
{{pageBitmap}} to the GenericRefinementRegion class. I tried something quick
and it worked immediately. So all there is to do is to find a better way to
implement this, e.g. if the {{GenericRefinementRegion}} can access the
{{JBIG2Page}} class.
