          Priority: medium
            Bug ID: 71104
          Assignee: libreoffice-bugs at lists.freedesktop.org
           Summary: Frames/objects with background color and transparency
                    enabled print as transparent black
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: tmacalp at gmail.com
          Hardware: Other
            Status: UNCONFIRMED
           Version: 3.5.7.2 release
         Component: Printing and PDF export
           Product: LibreOffice

When printing via the (now default) pdf print engine under Linux, objects with
transparency enabled on a set background color are always printed as having a
transparent black background.  I have only tested this behavior with Writer
frames and Draw shapes, but assume it affects any object with similar
background properties.

Steps to reproduce
1. Create a new writer document
2. Insert -> Frame
3. Background tab
4. Change background color to any color (white in my example document)
5. Change transparency to 50%
6. OK
7. Print

Expected
Printed document's frame should print as it looks on-screen.  The background
color should be the same color as selected, just transparent.

Actual
The background color of the frame is transparent, but appears to ignore the
color selection.  This leads to a transparent dark gray background, even when
the color is set to a light color, like white.


Note that this only seems to affect printing via the pdf print engine under
Linux. Printing via postscript avoids this issue, but bug 67802 keeps us from
using postscript in LO 4.1.x.

I was able to reproduce this behavior in all libreoffice versions I've had
access to under Linux from 4.1.2 back to 3.5.7 using 64bit RHEL6, 32bit Fedora
17, and 64bit Arch Linux(updated as of 10/31/13).  I assume it affects all
versions of LO going back to release.  Since I can only test it back to 3.5.7,
I'll mark that as the version.

I wasn't able to reproduce this behavior under MS Windows, so I assume that it
just affects printing from Linux.  Then again, I'm not sure what print engine
is being used as the printing system is obviously quite different.
