resize: Resize an 'Image'

In neuroconductor-devel/Rvision: Basic Computer Vision Library

Description

resize returns a resized version of an Image.

Usage

resize(image, height = NULL, width = NULL, fx = NULL, fy = NULL,
  interpolation = "linear")

Arguments

image	An Image object.
height	A positive integer representing the new height in pixels of the image (default: NULL).
width	A positive integer representing the new width in pixels of the image (default: NULL).
fx	A positive numeric representing the ratio by which the width of the image must be resized (default: NULL). Ignored if width is set.
fy	A positive numeric representing the ratio by which the height of the image must be resized (default: NULL). Ignored if height is set.
interpolation	A character string representing the type of interpolation to use during resizing (default: "linear"). See notes for all accepted interpolation methods.

Value

An Image object.

Note

The following interpolation methods are supported:

• "nearest": nearest neighbor interpolation.

• "linear": bilinear interpolation.

• "cubic": bicubic interpolation.

• "area": resampling using pixel area relation.

• "Lanczos": Lanczos interpolation over 8x8 neighborhood.

• "exact": bit exact bilinear interpolation.
