The intensity of the - blur can be controlled for each pixel using maskSource so that some parts of - the source are blurred more than others. - - Performing blur live is a costly operation.

The pixel alpha channel value from maskSource defines the - actual blur radius that is going to be used for blurring the - corresponding source pixel. - - Opaque maskSource pixels produce blur with specified - \l{MaskedBlur::radius}{radius}, while transparent pixels suppress the - blur completely. Semitransparent maskSource pixels produce blur with a - radius that is interpolated according to the pixel transparency level. - */ - property alias maskSource: maskProxy.input - - /*! - This property defines the distance of the neighboring pixels which - affect the blurring of an individual pixel. A larger radius increases - the blur effect. - - Depending on the radius value, value of the - \l{MaskedBlur::samples}{samples} should be set to sufficiently large to - ensure the visual quality. - - The value ranges from 0.0 (no blur) to inf.
