In OpenImageR: An Image Processing Toolkit

resize an image using the 'nearest neighbors' or the 'bilinear' method

Description

resize an image using the 'nearest neighbors' or the 'bilinear' method

Usage

resizeImage(image, width, height, method = "nearest", normalize_pixels = FALSE)

Arguments

image	matrix or 3-dimensional array where the third dimension is equal to 3
width	a number specifying the new width of the image. Corresponds to the image-rows.
height	a number specifying the new height of the image. Corresponds to the image-columns.
method	one of 'nearest', 'bilinear'
normalize_pixels	a boolean. If TRUE, then the output pixel values will be divided by 255.0

Details
