identify - describe an image or image sequence. SYNOPSIS
identify file [ file ... ] DESCRIPTION
Identify describes the format and characteristics of one or more image files. It will also report if an image is incomplete or corrupt. The information displayed includes the scene number, the file name, the width and height of the image, whether the image is colormapped or not, the number of colors in the image, the number of bytes in the image, the format of the image (JPEG, PNM, etc.), and finally the number of seconds it took to read and process the image. An example line output from identify follows: images/aquarium.miff 640x480 PseudoClass 256c 308135b MIFF 1s If -verbose is set, expect additional output including any image comment: Image: images/aquarium.miff class: PseudoClass colors: 256 signature: eb5dca81dd93ae7e6ffae99a527eb5dca8... matte: False geometry: 640x480 depth: 8 bytes: 308135 format: MIFF comments: Imported from MTV raster image: aquarium.mtv OPTIONS

Any option you specify on the command line remains in effect for the set of images immediately following, until the set is terminated by the appearance of any option or -noop.
