Hi ,
Currently i am trying to improve performance of my
window while drawing on that window.i am storing my each points into
one buffer on mouse down and mouse move event.and after that i am
calling [self setNeedDisplay:YES] method from mouseDown and
mouseDragged functions.
Now after lots of stroke getting stored into buffer
drawing speed is reduced by large amount of time.As a solution i think
of [self setNeedDisplayInRect:rect] method . whenever i try to draw
using this method my view area is getting flicker and my all stroke
are get flickered.
can anyone help me for this problem? or what could be
the reason for that. Thanks in advance.
Ravi.
