Description stephan66 2010-06-03 13:48:54 UTC
How to reproduce in DEV300m80:

- select a data series in a graph in Calc, and set transparency to non-zero value
- print graph

Any data series with transparancy > 0% is positioned incorrectly in the graph.
There is an offset in both the x and y positions.

Tested with 3 different (networked) printers, using 3 different drivers: HPLJ
4350 and two "Develop" color copiers/printers.

Used DEV300m80 from (on openSuSE 11.0, x86_64).

Problem does not occurr in 3.2.0 on the same printers. Could this
be a regression caused by the inclusion of CWS vcl106?

I see this also, testing OOO330_m6 on Fedora Linux 13; attaching screen captures
comparing output from OOo 3.2.1 and OOO330_m6.

Note: This is a regression compared to OOo 3.2.1.

The sample problem affects thick semi-transparent lines printed from OOo Draw.
Do we need a separate issue for that?

Also, in the image I attached, you can see there is a difference in the chart
frame rendering as well. It does not seem to be simply a matter of hairline
rendering in the PS output, because the Postscript from the same chart,
generated in OOo 3.2.1 and viewed at the same zoom, looks fine. Zooming in on
the PS rendering does make some parts of the frame/axes visible, but not all.

Hi Iha,
one for you.
Comment 6 stephan66 2010-08-31 13:32:36 UTC
My advice is not to expose end-users to this defect. 

This means: Target milestone:= OOo 3.3
Comment 7 stephan66 2010-09-10 16:02:01 UTC
Just used the test case with 3.3.0 beta 1: Problem is still there.
Comment 8 IngridvdM 2010-09-28 14:22:38 UTC
Back from vacation I found this issue assigned to me. I can confirm the problem
also on windows. It is a regression compared to OOo 3.2.1. It seems to be a
problem in the printing routine. Philipp, please have a look whether this can be
fixed for 3.3 still. I consider this to be a serious bug. The printed charts
show false data.

This does not seem to be an OLE object issue, however: if I copy the embedded
drawing from iha's sample to a new Draw document, as normal drawing shapes, it
shows the same problem when I print (to file) from Draw.

The PDF export of the same drawing is fine.

fixed in CWS ooo33gsl10
Comment 12 stephan66 2010-10-05 14:56:32 UTC
Thanks, pl!

I will test the BETA or RC release that merges this CWS.

BTW: The new printing system fixes a lot of problems of my colleagues with OOo
in one go. Excellent work, OOo crew!

Testing "OOo-dev 3.3  330m10(Build:9533)" on Fedora Linux 13:

Looks good: printing & print to file/Postscript render have the correct
appearance for each test document. The middle two lines in the OLE sample render
poorly, but I think that's a different problem related to embedded objects: the
lines all render properly if I copy/paste them into a Draw document and print.
