pyctools.components.interp.imageresizer.ImageResizerX	Horizontal image resizer component.
pyctools.components.interp.imageresizer.ImageResizerY	Vertical image resizer component.
pyctools.components.interp.imageresizer.ImageResizer2D	2-D image resizer component.

class ImageResizerX(config={}, **kwds)

Bases: Compound

Horizontal image resizer component.

Uses a Compound component to encapsulate Resize and FilterGenerator components.

Config:

up	int	Up-conversion factor.
down	int	Down-conversion factor.
aperture	int	Filter aperture.

class ImageResizerY(config={}, **kwds)

Bases: Compound

Vertical image resizer component.

Uses a Compound component to encapsulate Resize and FilterGenerator components.

Config:

up	int	Up-conversion factor.
down	int	Down-conversion factor.
aperture	int	Filter aperture.

class ImageResizer2D(config={}, **kwds)

Bases: Compound

2-D image resizer component.

Uses a Compound component to encapsulate two Resize and two FilterGenerator components.

Using separate Resize components to filter each dimension is a lot quicker than using one Resize with a 2-D filter, particularly for large apertures.

Config:

xup	int	Horizontal up-conversion factor.
xdown	int	Horizontal down-conversion factor.
xaperture	int	Horizontal filter aperture.
yup	int	Vertical up-conversion factor.
ydown	int	Vertical down-conversion factor.
yaperture	int	Vertical filter aperture.
