AT_ERRCOUNT ACCUAPI IG_colorspace_conversion_create_from_matrix(
        enumIGColorSpaceIDs sourceSpace,
        const AT_INT* sourceChannelDepths,
        AT_INT sourceChannelCount,
        enumIGColorSpaceIDs resultSpace,
        const AT_INT* resultChannelDepths,
        AT_INT resultChannelCount,
        HIGDoubleMatrix conversionMatrix,       
        LPCAT_COLORSPACE_CONVERSION_OPTIONS options,
        HIGCSCONVERTER* hCSConverter
);

Arguments:

Name	Type	Description
sourceSpace	enumIGColorSpaceIDs	Source color space.
sourceChannelDepths	const AT_INT*	Array of channel depths for source color space.
sourceChannelCount	AT_INT	Number of channels in source color space.
resultSpace	enumIGColorSpaceIDs	Color space to which to convert.
resultChannelDepths	const AT_INT*	Array of channel depths in resulting color space.
resultChannelCount	AT_INT	Number of channels in resulting color space.
conversionMatrix	AT_INT	Conversion matrix.
options	LPCAT_COLORSPACE_CONVERSION_OPTIONS	Reserved for future use.
hCSConverter	HIGCSCONVERTER*	Returns the handle of color space converter.

Return Value:

Returns the number of ImageGear errors that occurred during this function call.

Supported Raster Image Formats:

All pixel formats supported by ImageGear for C and C++.

Remarks:

Destination pixels are calculated as Dst = M * Src, where M is conversion matrix. Number of channels after conversion will be equal to first dimension of the conversionMatrix. Second dimension of conversionMatrix should be equal to number of channels in the source image.
