Bug ID: 91254
Summary: Very strange EMF+ corruption on Linux and OS X
Product: LibreOffice
Version: 4.3 Daily
Hardware: Other
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: graphics stack
Assignee: [email protected]

Anonymized bugdoc (EMF+)
The attached EMF+ image is not opened correctly on Linux, lines are not shown
(e.g. arrow lines).
* The bug was originally found on Linux (64-bit).
* The bug is not reproduced on Windows (both 32-bit and 64-bit).
* The chart looks terribly broken with OS X builds. Only text elements are
displayed.
* On all platforms rendering is OK with EMF_PLUS_DISABLE=1, not perfect of
course, because the EMF+ image has more details.
* I bisected the problem on Linux, and the first bad commit was mine, but in my
opinion it only triggered the bug, because it seems to be unrelated.

EMF/WMF: parse line cap and line join
I was surprised, that the following patch fixed the bug on Linux (but not on OS
X):
diff --git a/vcl/source/filter/wmf/enhwmf.cxx
b/vcl/source/filter/wmf/enhwmf.cxx
index c314ef6..152bee6 100644
