Hi, I'm performing my own graphics rendering using background images, which are then placed onto the resulting Carbon/Cocoa view. I can perform the whole rendering manually (by accessing the image data), but for some reason this seems quite slow compared to the same thing on Windows (probably the final conversion to system image, which isn't needed on Windows). Anyway I'd like to use the Quarz functions to optimize something, or at least avoid the final conversion to the system image. Is there a way to create an image, which can be then manipulated directly as well as using system drawing functions like it is on Windows? So far I tried CGImageCreate + CGContextDrawImage and CGBitmapContextCreateImage + CGContextDrawImage and both cases are just slow.
