virtual void area_enlarge (Geom::IntRect &area, Geom::Affine const &m) const
 
virtual void set_input (int slot)
 Sets the input slot number 'slot' to be used as input in rendering filter primitive 'primitive' For filter primitive types accepting more than one input, this sets the first input.
 
virtual void set_input (int input, int slot)
 Sets the input slot number 'slot' to be user as input number 'input' in rendering filter primitive 'primitive' First input for a filter primitive is number 0.
 
virtual void set_output (int slot)
 Sets the slot number 'slot' to be used as output from filter primitive 'primitive' If output slot for a filter element is not set, one of the unused image slots is used.
 
void set_x (SVGLength const &length)
 Sets the filter primitive subregion.

Geom::Rect filter_primitive_area (FilterUnits const &units) const
 Returns the filter primitive area in user coordinate system.
 
virtual bool can_handle_affine (Geom::Affine const &) const
 Indicate whether the filter primitive can handle the given affine.
 
void setStyle (SPStyle const *style)
 Sets style for access to properties used by filter primitives.
