◆ set_input() [1/2]

void Inkscape::Filters::FilterDisplacementMap::set_input	(	int	input,
		int	slot
	)

overridevirtual

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.

For primitives with attributes 'in' and 'in2', these are numbered 0 and 1, respectively. If any of required input slots for a filter is not set, the output of previous filter primitive is used, or SourceGraphic if this is the first filter primitive for this filter.

Reimplemented from Inkscape::Filters::FilterPrimitive.

◆ set_input() [2/2]

void Inkscape::Filters::FilterDisplacementMap::set_input ( int slot )

overridevirtual

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.

If any of the required input slots is not set, the output of previous filter primitive is used, or SourceGraphic if this is the first primitive for this filter.
