------- Additional comments from [email protected] Wed Apr 8 13:40:33 +0000 2009 ------- AW: I experimented with adding some old code which i used to play around with own hairline-AAing. It uses a simple buffer class which allows to add single transparent, colored pixels and collects them in arrays. On Flush() it gets the needed part of the destination as Bitmpap, adds the changes and writes them back. Around eight algorithms for AAing are added. Believe it or not, that code is faster (!!!) than calling the XRender extension. It's not extremely fast (Bitmap Op's for each single polygon), but about twice as fast on my local X-Server as before. This is incredible, sad and a good proof that all our optimizations on our side of the problem will have no real effect. The problem is in the XRender extension, there are some out there which do support AA bad and not in HW. My test code is not in a usable condition and such a deep change would be too dangerous for OOo 3.1 release. It would also make OOO3.1 much slower on all systems where the XRender extension is well supported in HW. I cannot guess for how many people it will be slow and for how many it will be fast due to HW-acceleration used by the XRender extension, but i see no alternative in asking the people for whose it is slow, to switch off AAing and to look for a better XRender extension for their system. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
