void blender::compositor::BlurBaseOperation::get_area_of_interest	(	int	input_idx,
		const rcti &	output_area,
		rcti &	r_input_area )

overridevirtual

Get input operation area being read by this operation on rendering given output area.

Implementation don't need to ensure r_input_area is within input operation bounds. The caller must clamp it. TODO: See if it's possible to use parameter overloading (input_id for example).

Parameters

input_idx	Input operation index for which we want to calculate the area being read.
output_area	Area being rendered by this operation.
r_input_area	Returned input operation area that needs to be read in order to render given output area.

Reimplemented from blender::compositor::NodeOperation.

Reimplemented in blender::compositor::FastGaussianBlurOperation, blender::compositor::GaussianAlphaBlurBaseOperation, blender::compositor::GaussianBlurBaseOperation, blender::compositor::GaussianBlurReferenceOperation, and blender::compositor::GaussianBokehBlurOperation.
