plotImageArray: Plot a 3D array as an RGB image

In recolorize: Color-Based Image Segmentation

Plot a 3D array as an RGB image

Description

Does what it says on the tin. An extremely simple wrapper for graphics::rasterImage(), but maintains aspect ratio, removes axes, and reduces margins for cleaner plotting.

Usage

plotImageArray(rgb_array, main = "", ...)

Arguments

rgb_array	A 3D array of RGB values. Preferably output from png::readPNG(), jpeg::readJPEG(), recoloredImage, constructImage, or raster_to_array.
main	Optional title for plot.
...	Parameters passed to graphics::plot.

Value

No return value; plots image.

Examples

# make a 100x100 image of random colors
random_colors <- array(runif(100 * 100 * 3),
                       dim = c(100, 100, 3))
recolorize::plotImageArray(random_colors)

# we can also plot...a real image
corbetti <- system.file("extdata/corbetti.png",
                       package = "recolorize")
img <- png::readPNG(corbetti)
plotImageArray(img)
