Andreas Lehmk=C3=BChler 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.

> An XObjectForm has an optional form matrix to map the form space to user =

ransformation matrix to calculate the correct coordinates for every followi=
ng operation.
