cells with corrupted font

in Calc when cell content rotated on 90 degree and set Italic, then characters look wrong (as if each character is slightly rotated)
in attachment are cells with different font and screenshot of it on my comp.
produced on Fedora 64 bit in LibO 3.5.0 beta 2
ps: not all font are corrupted, approximately one half

Comment 3 Caolán McNamara 2012-01-17 05:28:33 UTC
must be artificial italic + rotated glyphs, i.e. vcl/generic/gdi/salgdi3.cxx X11SalGraphics::DrawServerFontLayout

this seems to work

If I understand cairo transformations correctly, they are "applied" in reverse order. And we need to shear the glyphs before rotating them. The nGlyphRotation stuff would most probably need adjustment too.

caolanm->dtardon: Thanks, can you give this a once over for sanity ?


I've updated qadevOOo/testdocs/vertical-testcase.odt and it looks sane for vertical CJK text using artificial italic
Comment 6 David Tardon 2012-01-23 04:27:18 UTC
sure, looks sane

how it looks for me

This is my screenshot, which looks ok, the git commits from help->about for me and this is 832cd0c-5cd8d9c-9eed775-f061262-4dba2d1. Can you paste in your help->about build-id as well.

hmm, I'm hoping your pull and build happened before my commit, can you pull and build again ?
Comment 12 sasha.libreoffice 2012-01-24 06:51:56 UTC
thanks for explanation!
I am new to git, and wrongly used fetch instead of pull.
Compiling ...
