colorConversionLinksFromProfile()

QList< KoColorConversionTransformationFactory * > RgbU8ColorSpaceFactory::colorConversionLinksFromProfile ( const KoColorProfile * profile ) const

overridevirtual

colorConversionLinksFromProfile Sometimes, we need to generate special color conversion links based on the properties of the profile. The Perceptual Quantizer profiles are an example of this. This function is called inside the color conversion system.

Parameters

profile

– the profile for which to create the links for.

Reimplemented from KoColorSpaceFactory.

defaultProfile()

QString RgbU8ColorSpaceFactory::defaultProfile ( ) const

inlineoverridevirtual

Returns the default icc profile for use with this colorspace. This may be ""

Returns

the default icc profile name

referenceDepth()

int RgbU8ColorSpaceFactory::referenceDepth ( ) const

inlineoverridevirtual

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.

Implements KoColorSpaceFactory.

userVisible()

bool RgbU8ColorSpaceFactory::userVisible ( ) const

inlineoverridevirtual

Returns

true if the color space should be shown in a User Interface, or false otherwise.
