Read in an image as a 3D array

Reads in and processes an image as a 3D array. Extremely simple wrapper for imager::load.image(), but it strips the depth channel (resulting in a 3D, not 4D, array). This will probably change.

Usage

readImage(img_path, resize = NULL, rotate = NULL)

Arguments

img_path

Path to the image (a string).

resize

Fraction by which to reduce image size. Important for speed.

rotate

Number of degrees to rotate the image.

Value

A 3D RGB array (pixel rows x pixel columns x color channels). RGB channels are all scaled 0-1, not 0-255.

Examples

corbetti <- system.file("extdata/corbetti.png", package = "recolorize")
img <- readImage(corbetti)
plotImageArray(img)
