pure virtual

Returns: the list of color conversion provided by this colorspace, the factories constructed by this functions are owned by the caller of the function

◆ colorConversionLinksFromProfile()

virtual QList< KoColorConversionTransformationFactory * > KoColorSpaceFactory::colorConversionLinksFromProfile ( const KoColorProfile * profile ) const

◆ profileIsCompatible()

virtual bool KoColorSpaceFactory::profileIsCompatible ( const KoColorProfile * profile ) const

profile a pointer to a color profile

Implemented in KoSimpleColorSpaceFactory, and LcmsColorSpaceFactory.

◆ referenceDepth()

virtual int KoColorSpaceFactory::referenceDepth ( ) const

pure virtual

Returns: the reference depth, that is for a color space where all channels have the same depth, this is the depth of one channel, for a color space with different bit depth for each channel, it's usually the highest bit depth. This value is used by the Color Conversion System to check if a lost of bit depth during a color conversion is acceptable, for instance when converting from RGB32bit to XYZ16bit, it's acceptable to go through a conversion to RGB16bit, while it's not the case for RGB32bit to XYZ32bit.
