I'm working on cleaning up the GraphicDefs.h public header in the
interface kit.
Does anyone see issues with the following color space comments?
// color spaces
typedef enum {
B_NO_COLOR_SPACE = 0x0000,
// linear color space (little endian)
B_RGB32 = 0x0008, // BGRx xRGB 8:8:8:8
B_RGBA32 = 0x2008, // BGRA ARGB 8:8:8:8
B_RGB24 = 0x0003, // BGR RGB 8:8:8
B_RGB16 = 0x0005, // BGR RGB 5:6:5
B_RGB15 = 0x0010, // BGRx xRGB 1:5:5:5
B_RGBA15 = 0x2010, // BGRA ARGB 1:5:5:5
B_CMAP8 = 0x0004, // 256 color index table
B_GRAY8 = 0x0002, // 256 greyscale table
B_GRAY1 = 0x0001, // Each bit represents a single pixel
// big endian version
B_RGB32_BIG = 0x1008, // xRGB BGRx 8:8:8:8
B_RGBA32_BIG = 0x3008, // ARGB BGRA 8:8:8:8
B_RGB24_BIG = 0x1003, // RGB BGR 8:8:8
B_RGB16_BIG = 0x1005, // RGB BGR 5:6:5
B_RGB15_BIG = 0x1010, // xRGB BGRx 5:5:5:1
B_RGBA15_BIG = 0x3010, // ARGB BGRA 5:5:5:1
The BeBook goes a little crazy not documenting RGB24 and documenting
RGB16 as xRGB 5:6:5 which makes *no* sense.
