Tilman Hausherr updated PDFBOX-2283:
------------------------------------
Description:
The attached file (from the ghostscript installation) doesn't render properly,
especially page 3, where the images are about double the size. The cause is
that the transform for the appearance stream must be calculated based on the
BBox and the appearance rectangle and the matrix (if available). This is
described in "Algorithm: Appearance streams" in the "Appearance Streams"
section of the spec.
I have already prepared a fix, which I will commit after PDFBOX-2262.
Update: this issue is also about signatures and acroform fields, because these
have also appearance streams that are rendered with the same code.
