Detailed Description

Filter which applies a relative adjustment to a (virtual) color channel based on the value of another. The amount of adjustment for a given input is controlled by a user-defined curve.

createConfigurationWidget()

KisConfigWidget * KisCrossChannelFilter::createConfigurationWidget ( QWidget * parent, const KisPaintDeviceSP dev, bool useForMasks ) const

overridevirtual

Create the configuration widget for this processor.

Parameters

parent	the Qt owner widget of this widget
dev	the paintdevice this filter will act on
useForMasks	shown if the filer is going to be used in a mask. Some filters may provide limited options when applied as a mask (e.g. Gaussian Blur)

Reimplemented from KisBaseProcessor.

Definition at line 332 of file kis_cross_channel_filter.cpp.

{
    return new KisCrossChannelConfigWidget(parent, dev);

createTransformation()

KoColorTransformation * KisCrossChannelFilter::createTransformation ( const KoColorSpace * cs, const KisFilterConfigurationSP config ) const

overridevirtual

Create the color transformation that will be applied on the device.

Implements KisColorTransformationFilter.
