transparency in charts garbles PRINT PREVIEW.
Product: LibreOffice
Version: 5.1.2.2 release
Hardware: All
OS: Mac OS X (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Calc

Hybrid PDF containing its ODS source document.
Attached PDF file is generated from LibreOffice Calc.
As an LO Hybrid PDF, it contains the ODS source file, and as such contains all
the means to reproduce the observed bugs. The exported PDF itself is good --
the bugs are in how LO Calc...
...displays document parts in the "NORMAL" DOCUMENT VIEW itself,
...displays document parts the PRINT PREVIEW.
In order to see the bugs, you should:
1. Open PDF with a proper PDF viewer (DONT' open it in LO!).
2. Extract ODS source from PDF (you should know how to do this) and
open it in LO.
You can then observe at least two different bugs:
-------------------------------------------------------------------------
1. FONT COLOR IN ODS "NORMAL" DOCUMENT VIEW:
The font color of the "Factsheet VfB Stuttgart..." headline in LO view
appears as black on red background.
However, this font color in reality is defined as yellow.
--------------------------------------------------------------------------
2. WEIRD ARTIFACTS IN PRINT PREVIEW OF CHARTS:
Use menu "File -> Print Preview", and the same headline now appears in
correct coloring.
However, now all the included charts do appear very garbled. It seems
that the transparency setting for the trend line causes all the arti-
facts. Removing the transparency on the ODS source will remove the
artifacts in the print preview.
-------------------------------------------------------------------------
You can remove the "weirdness" from the print preview by removing the
transparency setting of "35%" from the trend lines inside the charts and
setting it to "0%".
SEVERITY:
1. If you are a user trying to create charts from ODS spreadsheets, these
bugs can make your workflow almost non-functional -- unless you know
that the exported PDF will be un-affected by the buggy preview.
2. You can then work around it, by routinely exporting to PDF and look at
THAT output -- but this is slowing down your working speed in a heavy
way.
I myself spent many hours of trying to get the font color working correctly by
relying on what LibreOffice displayed to me in its own "normal" document view.
The same is true for me trying to get transparency working in exported PDF by
relying on the print preview....
============================================================================
In case you only want to only take a quick look first, and currently don't have
time to download the hybrid PDF and take the trouble to reproduce the bug:
==> I'll also attach a PNG which depicts screenshots exemplifying all points
outlined above.
