           Summary: Evince PDF seems to ignore /Matrix in /XObject
           Product: poppler
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: cairo backend
        AssignedTo: poppler-bugs at lists.freedesktop.org
        ReportedBy: carlosgc at gnome.org


Bug forwarded from Evince: https://bugzilla.gnome.org/show_bug.cgi?id=628597

"The Story:
I had a pdf-image, that was rotated using pdftk. This image was included in a
pdflatex run as embedded image. The resulting pdf is correctly displayed in
Adobe Reader, but within Evince, this image is unrotated (off be 90°)...
Unfortunately I cannot give the example, but I'll try to come up with a
test-file within a few days...

For now, my analysis of the pdf shows that there is the following sequence
within the pdf:
12 0 obj <<
/Type /XObject
/Subtype /Form
/FormType 1
/PTEX.FileName (C:/the/path/to/rotated_picture.pdf)
/PTEX.PageNumber 1
/PTEX.InfoDict 28 0 R
/Matrix [0 -1 1 0 0 596.25]
/BBox [0 0 596.25 843]
/Group 13 0 R
/Resources <<
/ExtGState <<
/s5 29 0 R
.....

My guess would be that Evince does not correctly parse the /Matrix for the
XObject, as the Matrix
0 -1
1 0
would correspond to the missing rotation...

Best regards,
Chewi"

Test case is attached to the original bug report. I confirm it works with
splash.
