# ImageMagick Escapes

Use the -format option to print properties associated with an image in a format of your choosing. You can include the image filename, type, width, height, EXIF data, or other image attributes by embedding special format characters:

       %b   file size of image read in
       %c   comment meta-data property
       %d   directory component of path
       %e   filename extension or suffix
       %f   filename (including suffix)
       %g   layer canvas page geometry   ( = %Wx%H%X%Y )
       %h   current image height in pixels
       %i   image filename (note: becomes output filename for "info:")
       %k   CALCULATED: number of unique colors
       %l   label meta-data property
       %m   image file format (file magic)
       %n   number of images in current image sequence
       %o   output filename  (used for delegates)
       %p   index of image in current image list
       %q   quantum depth (compile-time constant)
       %r   image class and colorspace
       %s   scene number (from input unless re-assigned)
       %t   filename without directory or extension (suffix)
       %u   unique temporary filename (used for delegates)
       %w   current width in pixels
       %x   x resolution (density)
       %y   y resolution (density)
       %z   image depth (as read in unless modified, image save depth)
       %A   image transparency channel enabled (true/false)
       %C   image compression type
       %D   image GIF dispose method
       %G   image size ( = %wx%h )
       %H   page (canvas) height
       %M   Magick filename (original file exactly as given,  including read mods)
       %O   page (canvas) offset ( = %X%Y )
       %P   page (canvas) size ( = %Wx%H )
       %Q   image compression quality ( 0 = default )
       %S   ?? scenes ??
       %T   image time delay (in centi-seconds)
       %W   page (canvas) width
       %X   page (canvas) x offset (including sign)
       %Y   page (canvas) y offset (including sign)
       %Z   unique filename (used for delegates)
       %@   CALCULATED: trim bounding box (without actually trimming)
       %#   CALCULATED: 'signature' hash of image values
       %%   a percent sign
       \n   newline
       \r   carriage return
       < less-than character.
       > greater-than character.
      & ampersand character.

Here is a sample command and its output for an image with filename `bird.miff` and whose width is 512 and height is 480.

$ identify -format "%m:%f %wx%h" bird.miff MIFF:bird.miff 512x480

Additional properties are recognized when enclosed in braces:

       %[base]                 base filename, no suffixes (as %t)
       %[channels]             ??? channels in use - colorspace ???
       %[colorspace]           Colorspace of Image Data (excluding transparency)
       %[copyright]            ImageMagick Copyright String
       %[depth]                depth of image for write (as input unless changed)
       %[directory]            directory part of filename (as %d)
       %[extension]            extention part of filename (as %e)
       %[group]                ??? window group ???
       %[height]               original height of image (when it was read in)
       %[kurtosis]             CALCULATED: kurtosis statistic of image
       %[magick]               coder used to read image (not the file suffix)
       %[max]                  CALCULATED: maximum value statistic of image
       %[mean]                 CALCULATED: average value statistic of image
       %[min]                  CALCULATED: minimum value statistic of image
       %[name]                 The original name of the image
       %[opaque]               CALCULATED: is image fully-opaque?
       %[page]                 Virtual canvas (page) geometry
       %[resolution.y]         X density (resolution) without units
       %[resolution.x]         Y density (resolution) without units
       %[zero]                 zero (unique filename for delegates
       %[scene]                original scene number of image in input file
       %[size]                 original size of image (when it was read in)
       %[skewness]             CALCULATED: skewness statistic of image
       %[standard-deviation]   CALCULATED: standard-deviation statistic of image
       %[unique]               unique temporary filename ???
       %[version]              Version Information of this running ImageMagick
       %[width]                original width of image (when it was read in)
       %[*]                    list of image property strings

Use `%[fx:...]` to evaluate FX expressions:

       %[fx:expression]

Use `pixel:` to evaluate a pixel color as defined by the FX expression:

       %[pixel:expression]

You can also use the following special formatting syntax to print EXIF information contained in the file:

       %[EXIF:tag]

Choose tag from the following:

       *  (print all EXIF tags, in keyword=data format)
       !  (print all EXIF tags, in tag_number data format)
       #hhhh (print data for EXIF tag #hhhh)

Surround the format specification with quotation marks to prevent your shell from misinterpreting any spaces and square brackets.
