typedef struct _CIECHROMA {
LDECI4 x;
LDECI4 y;
LDECI4 Y;
} CIECHROMA;
The CIECHROMA structure is used to describe the chromaticity coordinates, x and y, and the luminance, Y in CIE color space. This structure is used by the COLORINFO structure to define colors for GDIINFO.
Members
x
Specifies the x coordinate in CIE chromaticity space.
y
Specifies the y coordinate in CIE chromaticity space.
Y
Specifies the luminance.
Comments
The LDECI4 type is used to represent real numbers to four decimal points. For example, (LDECI4) 10000 represents real number 1.0000, and (LDECI4) -12345 represents -1.2345.
Both x and y should be in the range zero to one. The Y member should be in the range 0 to 100.
