[FOP-2850] Rotated PDF files included with <fo:external-graphic> are misplaced

• Type: Bug
• Status: Open
• Priority: Major

• Affects Version/s: 2.3
• Environment: Windows 10 ; JDK8 64bit ; fop 2.3 ; fop-pdf-images 2.3

Description

I've stumbled upon an issue when including PDF files with a rotation angle (e.g. 90 degrees) with fo:external-graphic. The included PDF graphic overlaps with the previous block in the output PDF. My guess is that somehow width and height are mixed up in the process.

As a workaround it is possible to undo the rotation and fix the paper size of the included PDF before actually creating the result PDF with FOP. In this case the graphic is correctly placed inside the block.

I've attached the necessary files to this issue. I've also created a reproducer application on GitHub so this can be easily reproduced:
