Here are the choices:
enum RBPixelType
{
kRBPixelRGB24 = 1, // 3 bytes/pixel: Red, Green,
Blue
kRBPixelBGR24, // 3 bytes/pixel: Blue, Green,
Red
kRBPixelXRGB32, // 4 bytes/pixel: Unused, Red,
Green, Blue
kRBPixelBGRX32 // 4 bytes/pixel: Blue, Green,
Red, Unused
};
Funny thing is that whichever one I pick yields the same resulting component
arrangement. If I pass in "5" through "10", thinking maybe this enum didn't get
updated, I get a nil picture back. Console (WE) app.
