Hello,

I just installed 5.2.1.2 and nothing has changed. The Text in the EMF images is completly wrong in size!

I'm a long time user of OpenOffice (since StarOffice 2.0 for Windows) and I'm not aware of any OpenOffice version that has problems with rendering WMF/EMF files. 
Because of the good implementation for the WMF/EMF vector graphics rendering, my company has used this format in several tools that generates ODF documents.

Currently we use OpenOffice 4.1.1, just because of this bug. Otherwise we would use LibreOffice.

Best regards,
Jörg

Hi Joerg, I tested both images with v5.2.1.2, and "graph" (filename: test.emf) looks exactly the same imported in Writer as it is when opened in Paint.
"Copper phthalocyanine molecule in vector format" still looks wrong, that's why the report is still open (and it seems the two issues weren't related).

If you think you got some good examples of this bug, feel free to upload example files, or if you think yours is different, file a new bug report. Even if the title suggests this is some kind of generic bug report, it isn't, and generally each issue is supposed to go in a separate report.

Note that currently there are more than 11k issues open in LibreOffice bugzilla, and unless someone takes particular interest in this, the chance of significant improvement in EMF handling is slim.

For me it looks different, I will attach screenshots how the graphic is rendered by LO5.3.1.2 form. My LO version is:

Original issue with attachment 116809 [details] reproduced in LO 6.4+.
I cleaned some posts about other different example.
