Im in the process of learning Quartz 2D programming API, and im
trying to display a tiled image in a NSView, i wrote this code for
creating a valid bitmap context and a routine for displaying a
tiled image, but nothing is displayed, im not sure what`s wrong
because my printf debugging statements show good info about the
creation of the CGcontext and the loading of the image, any help
will be appreciated, thanks:
Your not drawing into the window at all. You need to get the
CGContext to draw to from the current NSGraphicsContext via:
CGContextRef context = (CGContextRef)[[NSGraphicsContext
currentContext] graphicsPort];
The bitmap context stuff you have looks like a red herring.
