createConfigurationWidget()

KisConfigWidget * KisFilterFastColorOverlay::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 108 of file KisFilterFastColorOverlay.cpp.

{
    // Use the normal blending mode (OVER is "normal").
    // This offers the best performance, but will change the color of all opaque pixels,
    // which may be unexpected in some situations (for example, coloring a scanned sketch on a white background).
    return COMPOSITE_OVER;
}

defaultConfiguration()

KisFilterConfigurationSP KisFilterFastColorOverlay::defaultConfiguration ( KisResourcesInterfaceSP resourcesInterface ) const

overridevirtual

Return the configuration set as the default by the user or the default configuration from the filter writer as returned by factoryConfiguration.

This configuration is used by default for the configuration widget and given to the process function if there is no configuration widget.

Returns

the default configuration of this widget

processImpl()

void KisFilterFastColorOverlay::processImpl ( KisPaintDeviceSP device, const QRect & applyRect, const KisFilterConfigurationSP config, KoUpdater * progressUpdater ) const

overridevirtual

Override this function with the implementation of your filter.

This is a low level function that expects all the conditions for the

Parameters

device	be met. Use usual process() methods instead.
device	the paint device to filter
applyRect	the rectangle where the filter is applied
config	the parameters of the filter
progressUpdater	to pass on the progress the filter is making
