Arguments

x	a greyscale image, with grey levels coded in ⁠[0, 1]⁠. This can be either a 2D matrix of pixels or a 4D imager::cimg() object.

Examples

# check that the overall grey level is reflected in the plot
img_show(matrix(runif(100, 0, 0.5), nrow=10))
img_show(matrix(runif(100, 0.5, 1), nrow=10))

# display an image
path <- system.file("extdata", "blob.jpg", package="morphr")
x <- img_read(path)
