------- Additional comments from [EMAIL PROTECTED] Wed Feb 9 03:42:02 -0800 2005 ------- In some important use cases OOo does way too many bitmap operations and they are also too slow. Examples of the useless conversions are from the device's image format into a bottom-up BGR bitmap, doing some operations on it and converting it back. Examples of the slow operations are SW implemented alpha-blending with three indirect functions calls per pixel and each pixel function does full position arithmetic (x+y*w) arithmetic. Best is to avoid redundant operations completely, but there is a risk involved. Since speeding bitmap operations up will also help the non-redundant cases it should be done. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
