[comp.sys.mac.programmer] CopyBits versus EraseRect

tarr-michael@CS.YALE.EDU (michael tarr) (11/29/90)

I wish to erase a rect on the screen to the background color. There are
two obvious ways:

1. EraseRect
2. CopyBits a rect of the same background.

Which is faster (my intuition is copybits -- eraserect appears very slow
on my system).

Thanks,

mike tarr
