public class Resize
extends AbstractJAITransformer

Resizes the image to predefined width and height.

Valid options are:

-D <int> (property: debugLevel)
    The greater the number the more additional info the scheme may output to 
    the console (0 = off).
    default: 0
    minimum: 0
 

-width <int> (property: width)
    The width to resize the image to; use -1 to use original width.
    default: -1
    minimum: -1
 

-height <int> (property: height)
    The height to resize the image to; use -1 to use original height.
    default: -1
    minimum: -1
 

-interpolation-type <NEAREST|BILINEAR|BICUBIC|BICUBIC2> (property: interpolationType)
    The type of interpolation to perform.
    default: BICUBIC
 

-num-subsample-bits <int> (property: numSubsampleBits)
    The number of bits to use for precision when subsampling.
    default: 8
    minimum: 1
