Description joerg.skottke 2008-12-16 20:30:54 UTC 
The attached document - based on the CD Cover template from StarOffice - shows
characters jumping around by random.

The last actions performed before this happened were:
* Insert text field
* Enter text
* Select text (CTRL+SHIFT+POS1)
* Select Font (URW Chancery L)
* Set font attribute Bold
* Exit selection

This happens with StarOffice OOO300m12 and OpenOffice.org OOO300m13, german,
Ubuntu Intrepid x86.

Comment 2 hdu@apache.org 2008-12-17 12:22:02 UTC 
the behaviour seems to depend on the font size: it doesn't happen if the font size is big enough
Comment 3 hdu@apache.org 2008-12-17 12:57:00 UTC 
also doesn't happen when the environment variable SAL_DISABLE_CAIROTEXT is set

Comment 5 hdu@apache.org 2008-12-17 16:18:31 UTC 
@cmc: yes, that seems to fix it. What's happening here? Does Cairo mess with our FT_Face's 
transformation?
Comment 6 caolanm 2008-12-17 16:25:20 UTC 
It must be doing so I'd guess
Comment 7 hdu@apache.org 2008-12-17 16:53:23 UTC 
@cmc: Thanks! The idea with FT_LOAD_IGNORE_TRANSFORM is great, as we don't use freetype's 
FT_Set_Transform() call ourselves (yet).

Fixed in CWS vcl98.

TODO: check for more non-transformation side effects from cairo on our FT_Face

Comment 9 hdu@apache.org 2008-12-18 15:23:01 UTC 
Adjusted the summary to the root cause.

Mixed text drawing is currently possible if any of these scenarios is involved: vertical writing, artifical 
boldness, disabled antialiasing (e.g. for masking or xor-based animations), glyph outlines e.g. in 
fontworks
