color_by_density: Color Images by density

In delabj/delabjGenArt:

Description

I think this code is adapted from a blog post by Will R Chase. This takes an image and maps new colors by density then saves the image with the new name. This uses EBImage from Bioconductor.

Usage

color_by_density(new_name, image_path, palette, mode = "grey")

Arguments

new_name	the new name for the file
image_path	the path to the source image
palette	the new palette to apply
mode	A character value specifying target mode for conversion using EBIImage See details

Details

Conversion Modes:

• "rgb": Converts a Grayscale image or an array into a Color image, replicating RGB channels.

• "gray" or "grey" Converts a Color image into a Grayscale image, using uniform 1/3 RGB weights.

• red, green, blue: Extracts the red, green or blue channel from a Color image. Returns a Grayscale image.

• asred, asgreen, asblue: Converts a Grayscale image or an array into a Color image of the specified hue.
