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
