I am using CALayers and a delegate to provide content with the method
- (void)drawLayer:(CALayer *)theLayer
inContext:(CGContextRef)theContext
in the method I use CGImage to draw .png bitmaps of numerals that
count up from 0. The .pngs all have transparency.
Everything works, the counter changes count, but as it changes you can
see a slight transition between the two digits.
It almost looks like a brief fade, but I don't have any animation
applied to it.
I've tried throwing in a CGContextClearRect right before drawing the
new bitmap, but it doesn't seem to work.
Any ideas why the drawing might be having this effect?
