Re: Creating a QCRenderer from a QCComposition

I am trying to create a QCRenderer with a QCComposition object like this

QCRenderer *renderer = [[QCRenderer alloc] initWithComposition:composition colorSpace:NULL];

How can I create a Color Space working with my QCRenderer ?


How about CGColorSpaceCreateWithName(kCGColorSpaceGenericRGB)?

Doesn't work with initWithComposition in my situation, I use an OpenGL context to render multiples Quartz Composition on my view.

The solution in this case is to use 

- (id) initWithCGLContext:(CGLContextObj)context pixelFormat:(CGLPixelFormatObj)format colorSpace:(CGColorSpaceRef)colorSpace composition:(QCComposition*)composition;

And create the color space with CGColorSpaceCreateWithName(kCGColorSpaceGenericRGB).

But I don't really understand why initWithComposition doesn't work in my situation.
