How to draw a CGImage object to a NSView?

Hi everyone. After reading the Quartz Graphics programming document, I am still trying to find a method to draw a CGImageRef object "directly" to a NSView / NSOpenGLView ...

My application decodes some files on the disk to into CGDataProvider, then uses the CGDataProviders to create CGImageRefs. I think it will cost too much performance to convert the CGImage objects to other formats, e.g. NSImage, CIImage. So I am wondering a direct way to draw CGImage to a NSView or NSOpenGLView.

Can anyone give me a suggestion? Thank you very much in advanced.
Good Luck.
