Me again. I've been using this code:
NSURL *url = [NSURL fileURLWithPath:fname];
CGImageSourceRef source = CGImageSourceCreateWithURL((CFURLRef)url,
NULL);
CGImageRef image = CGImageSourceCreateImageAtIndex(source, 0, NULL);
CFRelease(source);
theView.layer.contents = (id)image;
It compiles without complaint, but I'm still not seeing the image. I
can see the effects of changing other properties of the layer (e.g.
borderWidth). I've checked that image is not NULL. What am I missing
here?
You are probably missing a '[theView.layer setNeedsDisplay];'
BTW, I prefer drawing using the standard NS... classes by a delegate
and this code:
- (void) drawLayer:(CALayer *)layer inContext:(CGContextRef)ctx {
NSGraphicsContext *gc = [NSGraphicsContext
graphicsContextWithGraphicsPort:ctx flipped:NO];
[NSGraphicsContext saveGraphicsState];
[NSGraphicsContext setCurrentContext:gc];
// Draw stuff
[[NSColor redColor] setFill];
[NSBezierPath fillRect:NSMakeRect(8.0, 8.0, 48.0, 48.0)];
[NSGraphicsContext restoreGraphicsState];
}
Regards,
Patrick
