identify file [ file ... ]
 

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

For some formats, additional format-specific information about the file will be written if the -debug coder or -debug all option is used.

Options are processed in command line order. 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.

For a more detailed description of each option, see ImageMagick(1).
