I have a quick question, and I haven’t found a definitive answer through Google, so I thought I’d ask here: Is there a fast, easy way to get an NSImage from CGImageRef? A method I want to use in my program returns this.
I would also like to know how to do this. Does not seem to be documented well (if at all).
[[NSImage alloc] initWithCGImage:cgImage size:size];
You can pass NSZeroSize if you want NSMakeSize(CGImageGetWidth(cgImage), CGImageGetHeight(cgImage)). This argument is present because NSImage has a logical size that is distinct from its size in pixels. CGImage doesn’t.
// Create a bitmap rep from the image… NSBitmapImageRep *bitmapRep = [[NSBitmapImageRep alloc] initWithCGImage:cgImage]; // Create an NSImage and add the bitmap rep to it… NSImage *image = [[NSImage alloc] init]; [image addRepresentation:bitmapRep]; [bitmapRep release];
