Detailed Description

High-quality image resizing filter.

vtkImageResize will magnify or shrink an image with interpolation and antialiasing. The resizing is done with a 5-lobe Lanczos-windowed sinc filter that is bandlimited to the output sampling frequency in order to avoid aliasing when the image size is reduced. This filter utilizes a O(n) algorithm to provide good efficiency even though the filtering kernel is large. The sinc interpolator can be turned off if nearest-neighbor interpolation is required, or it can be replaced with a different vtkImageInterpolator object.
