COLORINFO

The COLORINFO structure defines a device's colors in CIE coordinate space.

typedef struct _COLORINFO {
  CIECHROMA  Red;
  CIECHROMA  Green;
  CIECHROMA  Blue;
  CIECHROMA  Cyan;
  CIECHROMA  Magenta;
  CIECHROMA  Yellow;
  CIECHROMA  AlignmentWhite;
  LDECI4  RedGamma;
  LDECI4  GreenGamma;
  LDECI4  BlueGamma;
  LDECI4  MagentaInCyanDye;
  LDECI4  YellowInCyanDye;
  LDECI4  CyanInMagentaDye;
  LDECI4  YellowInMagentaDye;
  LDECI4  CyanInYellowDye;
  LDECI4  MagentaInYellowDye;
} COLORINFO, *PCOLORINFO;

Members

Red, Green, Blue, Cyan, Magenta, Yellow, AlignmentWhite

Specify CIECHROMA structures that each define the x, y, and Y (luminance) coordinates of the named color.

RedGamma, GreenGamma, BlueGamma

Are the gamma corrections of display devices that permit the display device to display colors between the primary colors with accuracy. Their values should be between 0 and 6.5535, which means that the numbers actually stored in these members must be in the range 0 through 65535. See the Comments section for more information about this data type.

MagentaInCyanDye, YellowInCyanDye, CyanInMagentaDye, YellowInMagentaDye, CyanInYellowDye, MagentaInYellowDye

Used for printing devices to describe color purity and concentration. Values should be between zero and one, which means that the numbers actually stored in these members must be in the range 0 through 10000. See the Comments section for more information about this data type.

Comments

The LDECI4 type is used to represent real numbers to four decimal places. For example, (LDECI4) 10000 represents the real number 1.0000, and (LDECI4) -12345 represents -1.2345.

Any values in the COLORINFO structure that are out of the specified range default to the NTSC values.
