hte optional form matrix is present
[ https://issues.apache.org/jira/browse/PDFBOX-646?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andreas Lehmkühler updated PDFBOX-646:
--------------------------------------
Attachment: tiger-as-form-xobject.pdf
That file has an optional form matrix. The tiger doesn't show up using the PDFReader.
Jeremias provided me with that example long time ago. It's from the Apache FOP project.
