NAME
identify - describes the format and characteristics of one or more
image files.
SYNOPSIS
identify [options] input-file
OVERVIEW
The identify program is a member of the ImageMagick(1) suite of tools.
It describes the format and characteristics of one or more image files.
It also reports if an image is incomplete or corrupt. The information
returned includes the image 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 (by default off use -define unique=true option),
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. Many more attributes are available with the verbose option.

Usage: identify [options ...] file [ [options ...] file ... ]
Image Settings:
-alpha option on, activate, off, deactivate, set, opaque, copy
transparent, extract, background, or shape
-antialias remove pixel-aliasing
-authenticate password
decipher image with this password
-clip clip along the first path from the 8BIM profile
-clip-mask filename associate a clip mask with the image
-clip-path id clip along a named path from the 8BIM profile
-colorspace type alternate image colorspace
-crop geometry cut out a rectangular region of the image
-define format:option
define one or more image format options
-density geometry horizontal and vertical density of the image
-depth value image depth
-endian type endianness (MSB or LSB) of the image
-extract geometry extract area from image
-features distance analyze image features (e.g. contrast, correlation)
-format "string" output formatted image characteristics
-fuzz distance colors within this distance are considered equal
-gamma value of gamma correction
-interlace type type of image interlacing scheme
-interpolate method pixel color interpolation method
-limit type value pixel cache resource limit
-matte store matte channel if the image has one
-moments report image moments
-monitor monitor progress
-ping efficiently determine image attributes
-precision value maximum number of significant digits to print
-quiet suppress all warning messages
-read-mask filename associate a read mask with the image
-regard-warnings pay attention to warning messages
-respect-parentheses settings remain in effect until parenthesis boundary
-sampling-factor geometry
horizontal and vertical sampling factor
-seed value seed a new sequence of pseudo-random numbers
-set attribute value set an image attribute
-size geometry width and height of image
-strip strip image of all profiles and comments
-unique display the number of unique colors in the image
-units type the units of image resolution
-verbose print detailed information about the image
-virtual-pixel method
virtual pixel access method
Image Operators:
-channel mask set the image channel mask
-grayscale method convert image to grayscale
-negate replace every pixel with its complementary color
Miscellaneous Options:
-debug events display copious debugging information
-help print program options
-list type print a list of supported option arguments
-log format format of debugging information
-version print version information
By default, the image format of 'file' is determined by its magic
number. To specify a particular image format, precede the filename
with an image format name and a colon (i.e. ps:image) or specify the
image type as the filename suffix (i.e. image.ps). Specify 'file' as
'-' for standard input or output.

NOTE
Although some options appear to modify the file to be identified, the
identify command is strictly read only. For instance, the crop option
crops the in-memory image and then describes the result.
