Detailed Description

Image resampler for DPI-change operations, including upsampling and downsampling using bicubic interpolation resampling algorithm.

Constructor & Destructor Documentation

◆ BicubicImageResampler()

BicubicImageResampler ( ImageDpi targetDpi )

inlineexplicit

Constructs bicubic interpolation image resampler for a target DPI.

This constructor initializes the image resampler to resample an image to the specified DPI using bicubic interpolation.

Parameters

targetDpi The DPI (dots per inch) of the new image.

Exceptions

EnrollmentInvalidArgumentException when targetDpi is 0

It creates new image as result of resampling with factor target DPI/original DPI.

Parameters

image Image to resize.

Returns: image with given DPI
