I'm using the code at the bottom of the page of TN2143 (http:// developer.apple.com/technotes/tn2005/tn2143.html)

To wit:

NSSize            imageSize;
NSBitmapImageRep*  bitmapImage;

NSImage*  image = imgOut; // image from my qtz renderer

if(image) {
imageSize = [image size];
[image lockFocus];
bitmapImage = [[NSBitmapImageRep initWithFocusedViewRect:NSMakeRect(0, 0, size.width, size.height)];
[image unlockFocus];

CIImage* im = [[[CIImage alloc] initWithBitmapImageRep:bitmapImage] autorelease];
}

There is a typo in the technote sample code: it should read:

[[NSBitmapImageRep alloc] initWithFocusedViewRect:...
