History

#1 Updated by Constantin Asofiei almost 9 years ago

In GUI, ScreenBitmap.canDraw (and its callers, getVerticalFragments and getHorizontalFragments) are used intensively. The performance for canDraw is poor - it iterates all registered rectangles in ScreenBitmap.bitmap to determine if the specified point is part of it. This should be improved so that search is done faster: maintain some parallel sorted arrays by column/row, and use binary search on them?
