Graphics::PixelFormat Struct Reference

#include <pixelformat.h>

List of all members.


Detailed Description

A pixel format description.

Like ColorMasks it includes the given values to create colors from RGB values and to retrieve RGB values from colors.

Unlike ColorMasks it is not dependend on knowing the exact pixel format on compile time.

A minor difference between ColorMasks and PixelFormat is that ColorMasks stores the bit count per channel in 'kFooBits', while PixelFormat stores the loss compared to 8 bits per channel in 'Loss'. It also doesn't contain mask values.
