In pavo: Perceptual Analysis, Visualization and Organization of Spectral Colour Data

Convert images between class rimg and cimg or magick-image

Description

Conveniently convert single objects of class rimg to class cimg (from the package imager) or magick-image (from the package magick), both of which contains a suite of useful image-processing capabilities.

Usage

rimg2cimg(image)

rimg2magick(image)

Arguments

image

an object of class rimg

Value

an image of the specified class

Note

Attributes (e.g. scales, color-classes) will not be preserved following conversion from class rimg, so it's best to use early in the analysis workflow.
