Member Function Documentation

◆ createConfigurationWidget()

KisConfigWidget * KisLevelsFilter::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 30 of file KisLevelsFilter.cpp.

{
    return new KisLevelsConfigWidget(parent, dev, dev->compositionSourceColorSpace());
}

References KisPaintDevice::compositionSourceColorSpace().

◆ createTransformation()

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

overridevirtual

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

Implements KisColorTransformationFilter.

Definition at line 35 of file KisLevelsFilter.cpp.

    const KisLevelsFilterConfiguration *config_ = dynamic_cast<const KisLevelsFilterConfiguration*>(config.data());

◆ factoryConfiguration()

KisFilterConfigurationSP KisLevelsFilter::factoryConfiguration ( KisResourcesInterfaceSP resourcesInterface ) const

overridevirtual

Returns: the default configuration object as defined by whoever wrote the plugin. This object must be filled in with fromXML after that.

Reimplemented from KisColorTransformationFilter.

{
    return new KisLevelsFilterConfiguration(0, resourcesInterface);
