Scaler

Name	Type	Description
kind	enum                           default zscale	The type of scaling to be applied. default: default
algorithm	enum                           bilinear bicubic nearest_neighbor lanczos bicubic_spline spline16 spline36 sinc	The algorithm to be used for scaling operations. This will apply to both up-scale and down-scale. These may be set separately using the upscale_algorithm and downscale_algorithm parameters.
upscale_algorithm	enum                           bilinear bicubic nearest_neighbor lanczos bicubic_spline spline16 spline36 sinc	The algorithm to be used for up-scaling operations.
downscale_algorithm	enum                           bilinear bicubic nearest_neighbor lanczos bicubic_spline spline16 spline36 sinc	The algorithm to be used for down-scaling operations.
config_string	string	The configuration string to be used with the specified scaling function.
apply_always	boolean	Always use the specified scaling function.
