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
in both user time and elapsed time it took to read and process the image.
If -verbose or +ping are provided as an option, the pixel read rate is
also displayed. An example line output from identify follows:
images/aquarium.miff 640x480 PseudoClass 256c
308135b MIFF 0.000u 0:01
If -verbose is set, expect additional output including any image
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
