Member Function Documentation

◆ changedRect()

QRect KisPropagateColorsFilter::changedRect	(	const QRect &	rect,
		const KisFilterConfigurationSP	config,
		int	lod ) const

overridevirtual

Similar to neededRect : some filters will alter a lot of pixels that are near to each other at the same time. So when you changed a single rectangle in a device, the actual rectangle that will feel the influence of this change might be bigger. Use this function to determine that rect.

Reimplemented from KisFilter.

Definition at line 549 of file KisPropagateColorsFilter.cpp.

{
    return neededRect(rect, config, lod);
}

References neededRect().

◆ createConfigurationWidget()

KisConfigWidget * KisPropagateColorsFilter::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 520 of file KisPropagateColorsFilter.cpp.

{
    return new KisPropagateColorsConfigWidget(parent);
}

◆ factoryConfiguration()

KisFilterConfigurationSP KisPropagateColorsFilter::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 KisBaseProcessor.

Definition at line 515 of file KisPropagateColorsFilter.cpp.

{
    return new KisPropagateColorsFilterConfiguration(resourcesInterface);
}

◆ neededRect()

QRect KisPropagateColorsFilter::neededRect	(	const QRect &	rect,
		const KisFilterConfigurationSP	config,
		int	lod ) const

overridevirtual

Some filters need pixels outside the current processing rect to compute the new value (for instance, convolution filters)

Reimplemented from KisFilter.

Definition at line 535 of file KisPropagateColorsFilter.cpp.

{
    const KisPropagateColorsFilterConfiguration *filterConfig =
            dynamic_cast<const KisPropagateColorsFilterConfiguration*>(config.data());
 
    if (filterConfig->expansionMode() == KisPropagateColorsFilterConfiguration::ExpansionMode_Unbounded) {
        return rect;
    }
 
    const qint32 expansionAmount = static_cast<qint32>(std::ceil(filterConfig->expansionAmount()));
 
    return rect.adjusted(-expansionAmount, -expansionAmount, expansionAmount, expansionAmount);
}

◆ needsTransparentPixels()

bool KisPropagateColorsFilter::needsTransparentPixels	(	const KisFilterConfigurationSP	config,
		const KoColorSpace *	cs ) const

overridevirtual

Reimplemented from KisFilter.

Definition at line 527 of file KisPropagateColorsFilter.cpp.

    const KisPropagateColorsFilterConfiguration *filterConfig =

◆ processImpl()

void KisPropagateColorsFilter::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
