Converting Between Color Spaces /

CMConvertHSVToRGB

Converts colors specified in the HSV color space to equivalent colors defined in the RGB color space.

pascal CMError CMConvertHSVToRGB (
const CMColor *src, 
CMColor *dst, 
unsigned long count);

src

A pointer to an array containing the list of HSV colors to convert to RGB colors.

dst

A pointer to an array containing the list of colors, resulting from the conversion, as specified in the RGB color space.

count

The number of colors to convert.

function result

A result code of type CMError. See "Result Codes" (page 3-174) for a list of ColorSync-specific result codes.

DISCUSSION

The CMConvertHSVToRGB function converts one or more colors defined in the HSV color space to equivalent colors defined in the RGB color space. Both color spaces are device dependent.

If your application does not require that you preserve the source color list, you can pass the pointer to the same color list array as the src and dst parameters and allow the CMConvertHSVToRGB function to overwrite the source colors with the resulting converted color specifications.
