I'm trying to make a screensaver using the tutorial on cocoadevcentral. But
instead of drawing shapes, I wanna be able to draw pictures and perhaps move
then. Can anyone tell me how do that?
SO far I have this, but doesn't do anything:
- (void)animateOneFrame
{
NSImage *image;
NSRect myRect;
NSSize mySize;
image = [[NSImage imageNamed:@"mypict.jpg"] copy];
mySize = [image size];
myRect.origin.x = 0;
myRect.origin.y = 0;
myRect.size = mySize;
[image lockFocus];
[image drawInRect:[self bounds] fromRect:myRect
operation:NSCompositeCopy fraction:0.5];
[image unlockFocus];
}
