The following functions are to be implemented by color management modules (CMMs), and exported for the operating system to call.
| Function | Description |
|---|---|
| CMCheckColors | Determines whether given colors lie within the output gamut of a specified transform. |
| CMCheckColorsInGamut | Determines whether specified RGB triples lie in the output gamut of a specified transform. |
| CMCheckRGBs | Checks bitmap colors against an output gamut. |
| CMConvertColorNameToIndex | Converts color names in a named color space to index numbers in a color profile |
| CMConvertIndexToColorName | Transforms indices in a color space to an array of names in a named color space. |
| CMCreateDeviceLinkProfile | Creates a device link profile in the format specified by the International Color Consortium in its ICC Profile Format Specification. |
| CMCreateMultiProfileTransform | Accepts an array of profiles or a single device link profile and creates a color transform. This transform is a mapping from the color space specified by the first profile to that of the second profile and so on to the last one. |
| CMCreateProfile | Creates a display color profile from a LOGCOLORSPACEA structure. |
| CMCreateProfileW | Creates a display color profile from a LOGCOLORSPACEW structure. |
| CMCreateTransform | Deprecated. There is no replacement API because this one was no longer being used. Developers of alternate CMM modules are not required to implement it. |
| CMCreateTransformExt | Creates a color transform that maps from an input LOGCOLORSPACEA to an optional target space and then to an output device, using a set of flags that define how the transform should be created. |
| CMCreateTransformExtW | Creates a color transform that maps from an input LOGCOLORSPACEW to an optional target space and then to an output device, using a set of flags that define how the transform should be created. |
| CMCreateTransformW | Deprecated. There is no replacement API because this one was no longer being used. Developers of alternate CMM modules are not required to implement it. |
| CMDeleteTransform | Deletes a specified color transform, and frees any memory associated with it. |
| CMGetInfo | Retrieves various information about the color management module (CMM). |
| CMGetNamedProfileInfo | Retrieves information about the specified named color profile. |
| CMGetPS2ColorRenderingDictionary | Gets a PostScript color rendering dictionary. |
| CMGetPS2ColorRenderingIntent | Retrieves the PostScript Level 2 color rendering intent from a profile. |
| CMGetPS2ColorSpaceArray | Gets a PostScript color space array. |
| CMIsProfileValid | Reports whether the given profile is a valid ICC profile that can be used for color management. |
| CMTranslateColors | Translates an array of colors from a source color space to a destination color space using a color transform. |
| CMTranslateRGB | Translates an application-supplied RGBQuad into the device color space. |
| CMTranslateRGBs | Translates a bitmap from one color space to another using a color transform. |
| CMTranslateRGBsExt | Translates a bitmap from one defined format into a different defined format and calls a callback function periodically, if one is specified, to report progress and permit the calling application to terminate the translation. |
