Parameters

Parameter	Type	Default	Range	Description
`top_stretch` Top Stretch	float	0	-1 to 1	Narrows the top for positive values and widens it for negative values. Zero preserves its width.
`bottom_stretch` Bottom Stretch	float	0	-1 to 1	Narrows the bottom for positive values and widens it for negative values. Zero preserves its width.
`addressing` Addressing	enum	repeat		How transformed source coordinates outside 0-1 are handled. Repeat wraps sampling, but does not guarantee a tiling-safe transform. `background` : Fill out-of-bounds transformed areas with Background Color. `clamp` : Clamp out-of-range coordinates or values to the edge. `repeat` : Wrap out-of-range coordinates or values back into the 0-1 range.
`background_color` Background Color	color	[0, 0, 0, 1]		Color used when transformed coordinates fall outside the input.
`filter_mode` Filter	enum	bilinear		Texture filtering mode. `bilinear` : Use bilinear sampling for smoother resampling. `nearest` : Use nearest-neighbor sampling for hard pixel edges.
