Here is a special define that outputs the location of the minimum or maximum pixel of the image: magick identify -precision 5 -define identify:locate=maximum -define identify:limit=3 image.png To display the convex hull and minimum bounding box attributes of the image, use: magick identify -define identify:convex-hull=true image.png Here we display the image texture features, moments, perceptual hash, and the number of unique colors in the image: $ magick identify -verbose -features 1 -moments -unique image.png The depth and dimensions of a raw image must be specified on the command line: $ magick identify -depth 8 -size 640x480 image.raw To get the print size in inches of an image at 72 DPI, use: $ magick identify -format "% by % inches" document.png
