Details

imshow opens a regular graphics device, meaning that it is possible to overlay lines and points over the image, like with any regular plot. The bottom left corner of the image is set at {1,1}.

If the type of the vpImage object is "numeric", then its values are rescaled between 0 and 1, with 0 representing the minimum value of the original image and 1 representing its maximum.

Run this code

filename <- system.file("sample_img/SampleVideo_1080x720_5mb.png", package = "videoplayR")
img <- readImg(filename)
imshow(img)
