Enumeration Type Documentation

enum COLORSPACE

Color space enumeration, used to described how image/color data is stored in a memory buffer. Some colorspace values such as those having 'alpha' component may be treated identically to the similar values having a 'skip' component in the same position. In addition, some processes may treat gray and indexed colorspaces identically. Enumeration values: COLORSPACE_Unknown  COLORSPACE_Gray8  Grayscale 1 byte/pixel. Each component is accessed sequentially in the data using data elements of the size (in bits) specified. For components of more than 8 bits this is assumed to be in the NATIVE byte order of the machine and thus byte swapping may need to be performed when accessing from external sources. COLORSPACE_Gray16  Grayscale 2 bytes/pixel. COLORSPACE_Gray32  Grayscale 4 bytes/pixel. COLORSPACE_Indexed8  Indexed 1 byte/pixel. COLORSPACE_Indexed16  Indexed 2 bytes/pixel. COLORSPACE_R8_G8_B8  Red, Green, Blue, 1 byte each. COLORSPACE_B8_G8_R8  Blue, Green, Red, 1 byte each. COLORSPACE_R8_G8_B8_X8  Red, Green, Blue, Skip, 1 byte each. COLORSPACE_X8_R8_G8_B8  Skip, Red, Green, Blue, 1 byte each. COLORSPACE_B8_G8_R8_X8  Blue, Green, Red, Skip, 1 byte each. COLORSPACE_X8_B8_G8_R8  Skip, Blue, Green, Red, 1 byte each. COLORSPACE_R8_G8_B8_A8  Red, Green, Blue, Alpha, 1 byte each. COLORSPACE_A8_R8_G8_B8  Alpha, Red, Green, Blue, 1 byte each. COLORSPACE_B8_G8_R8_A8  Blue, Green, Red, Alpha, 1 byte each. COLORSPACE_A8_B8_G8_R8  Alpha, Blue, Green, Red, 1 byte each. COLORSPACE_C8_M8_Y8  Cyan, Magenta, Yellow, 1 byte each. COLORSPACE_C8_M8_Y8_X8  Cyan, Magenta, Yellow, Skip, 1 byte each. COLORSPACE_C8_M8_Y8_K8  Cyan, Magenta, Yellow, Black, 1 byte each. COLORSPACE_X8_C8_M8_Y8  Skip, Cyan, Magenta, Yellow, 1 byte each. COLORSPACE_K8_C8_M8_Y8  Black, Cyan, Magenta, Yellow, 1 byte each. COLORSPACE_Indexed4  4-bits per pixel colormapped COLORSPACE_Packed8_Binary_LowFirst  1 bit/pixel, low bit first along image line More than one pixel or component is 'packed' into a data element. The number after 'Packed' indicates the size of each data element in bits. For elements larger than 8 bits this is assumed to be in the NATIVE byte order of the machine and thus byte swapping may need to be performed when accessing data. When multiple components are packed into a data element they are listed in order from most-significant bits to least. COLORSPACE_Packed8_Binary_HighFirst  1 bit/pixel, high bit first along image line COLORSPACE_Packed8_Gray4_LowFirst  4 bits/pixel, low nibble first along image line COLORSPACE_Packed8_Gray4_HighFirst  4 bits/pixel, high nibble first along image line COLORSPACE_Packed8_Indexed4_LowFirst  Indexed 4 bits/pixel, low nibble first along image line. COLORSPACE_Packed8_Indexed4_HighFirst  Indexed 4 bits/pixel, high nibble first along image line. COLORSPACE_Packed16_X1_R5_G5_B5  0RRRRRGGGGGBBBBB COLORSPACE_Packed16_X1_B5_G5_R5  0BBBBBGGGGGRRRRR COLORSPACE_R16_G16_B16  sRGB as 16-bit per sample COLORSPACE_X16_Y16_Z16  CIE XYZ as 16-bit per sample fixed point. COLORSPACE_L16_a16_b16  CIE Lab as 16-bit per sample fixed point. Definition at line 50 of file colorspc.h.
