----------------------------------
Summary: Rendering of Type3 string fails with NPE
Key: PDFBOX-2137
URL: https://issues.apache.org/jira/browse/PDFBOX-2137
Project: PDFBox
Issue Type: Bug
Components: Rendering
Affects Versions: 2.0.0
Reporter: Petr Slaby
Rendering of the attached PDF fails with a NPE in PDFStreamEngine at the line
395 (float spaceWidthDisp = ...) because the textMatrix field is null. The
reason is that the textMatrix gets reset while processing the first character
of the string in PageDrawer#drawType3String(). The attached patch fixes the
problem, but I am not quite sure whether it is the right solution.
To debug this, set a breakpoint in PDFStreamEngine#processEncodedText() with
the condition "string.length == 2 && string[1] == 67" and watch the textMatrix
field vanish after the first character has been processed.
