GraphicsImportDraw bug or feature?

Apple Team,

Is the following code supported? It seems like a bug that it doesn't...

GetGraphicsImporterForFile(&fsSpec, &graphicsImporter);

rgbBufferPtr = NewPtr(width * height * 3);

QTNewGWorldFromPtr( &gWorld,
k24RGBPixelFormat,
&rect,
nil,
nil,
nil,
rgbBufferPtr,
width * 3);

GraphicsImportSetGWorld(graphicsImporter, gWorld, nil);
GraphicsImportDraw(graphicsImporter);
CloseComponent(graphicsImporter);


(I trimmed the excess for readability, but you get the idea.)

It doesn't work for me, but if I change the gWorld to a k32ARGB (using QTNewGWorld), it works fine.

Thanks,
Rob
