Description philipp.lohmann 2007-06-20 15:58:42 UTC 
There is no blend mode available in CG graphics that implements XOR like we need
it. CoreImage also does not seem to implement this.

For the time being we need a basebmp based solution for this; however as soon as
a better possibility comes along we should switch to that.

almost done in CS aquavcl01, only an issue during slideshow remains
Comment 2 philipp.lohmann 2007-06-21 19:31:51 UTC 
fixed in CWS aquavcl01

open: drawBitmap( const SalTwoRect* pPosAry, const SalBitmap& rSalBitmap, const
SalBitmap& rTransparentBitmap ), which IMHO has undefined behaviour in XOR anyway
open: drawing text in XOR -> followup
