◆ determineResolution()

void blender::compositor::ScaleFixedSizeOperation::determineResolution	(	unsigned int	resolution[2],

	)

overridevirtual

determine the resolution of this node

Note: this method will not set the resolution, this is the responsibility of the caller

Parameters

resolution	the result of this operation
preferredResolution	the preferable resolution as no resolution could be determined

		PixelSampler
	)

overridevirtual

calculate a single pixel

Note: this method is called for non-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
inputBuffers	chunks that can be read by their ReadBufferOperation.
