Description Barade 2015-06-16 14:09:12 UTC

While the BMP export image looks like the class diagram in Umbrello the SVG export does not.
I think that the font or the positions or both have changed.

Reproducible: Always

Comment 4 Ralf Habacker 2015-06-16 14:35:24 UTC

Here are some observation results on linux with version 2.16.99 using Qt 4.8.5:
1. The font setting in the xmi file (interface.xmi  -> Sans Serif,9) is transfered 1:1 into the svg file (interface.svg -> font-family="Sans Serif" font-size="9"). 
2. Changing the class diagram font size to 10 point shows the same vertical position and size of the methods as the exported bmp file
3. The vertical positions of the exported svg file looks like generated using a 10 point high font but displayed with 9 point size.

Fix 'SVG export image does not look like the actual diagram'.

The with and height of the exported file need to match the
font resolution to get what is displayed on the screen.
