overridevirtual

calculate a single pixel

Note: this method is called for complex

Parameters

result	is a float[4] array to store the result
x	the x-coordinate of the pixel to calculate in image space
y	the y-coordinate of the pixel to calculate in image space
input_buffers	chunks that can be read by their ReadBufferOperation.
chunk_data	chunk specific data a during execution time.

void blender::compositor::FastGaussianBlurOperation::get_area_of_interest	(	int	input_idx,

		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.
