I would like to generate a RGB thumbnail of a composition using QCRenderer's
createSnapshotImageOfType function but the function always returns a RGBA
type image. I have verified it by checking bytesPerRow property of the
return NSBitmapRep object and it always returns a multiple of 4
here is the code
QCComposition* composition = [QCComposition compositionWithFile:[path
stringByAppendingPathExtension:@"qtz"]];
CGColorSpaceRef colorSpace;
colorSpace = CGColorSpaceCreateWithName(kCGColorSpaceGenericRGB);
QCRenderer* renderer = [[QCRenderer alloc] initOffScreenWithSize:
NSMakeSize(153, 115) colorSpace:colorSpace composition:composition];
NSBitmapImageRep* bitmap = [renderer createSnapshotImageOfType:
@"NSBitmapImageRep"];
Is there a direct way to generate RGB image instead of RGBA? or should I
convert, Please help
Nisar
