NAME
    conjure - process a Magick Scripting Language (MSL) script

    WARNING:  Conjure and MSL are in very early development and the syntax
    is subject to change!

SYNOPSIS
    conjure [ options ] script.msl [ [ options ] script.msl ]

DESCRIPTION
    The Magick scripting language (MSL) will primarily benefit those that
    want to  accomplish custom image processing tasks but do not wish to
    program, or those that do not have access to a Perl interpreter  or a
    compiler.  The interpreter is  called conjure and here is an example
    script:

   <?xml version="1.0" encoding="UTF-8"?>
   <image size="400x400" >
    <read filename="image.gif" />
    <get width="base-width" height="base-height" />
    <resize geometry="%[dimensions]" />
    <get width="width" height="height" />
    <print output=
     "Image sized from %[base-width]x%[base-height]
  to %[width]x%[height].\n" />
    <write filename="image.png" />
   </image>

    invoked with

   conjure -dimensions 400x400 incantation.msl

    All operations will closely follow the key/value pairs defined in Perl-
    Magick, unless otherwise noted.

    Conjure is in the early stages of development as of April 2002.

    This early announcement is to allow ImageMagick users to contribute
    ideas early in the process so when the scripting language is released
    it will  be useful/stable from the get-go! If you want to contribute
    suggestions about the Magick scripting language (MSL), post them to
    magick-developers@imagemagick.org.

OPTIONS
    Options are processed in command line order. Any option you specify on
    the command line remains in effect until it is explicitly changed by
    specifying the option again with a different effect, or if it is
    changed by a statement in the scripting language.

    You can define your own keyword/value pairs on the command line.  The
    script can then use this information when setting values by including
    %[keyword] in the string. For example, if you included "-dimensions
    400x400"  on the command line, as illustrated above, then any string
    containing "%[dimensions]" would have  400x400  substituted.   The
    "%[string]" can  be used either an entire string, such as geome-
    try="%[dimensions]" or as a part of a string such as filename="%[base-
    name].png".

    The keyword can be any string except for the following reserved strings
    (in any upper, lower, or mixed case variant): debug, help, and verbose,
    whose usage is described below.

    The value can be any string. If either the keyword or the value con-
    tains white space or any symbols that have special meanings to your
    shell such as "#", "|", or "%", enclose the string in quotation marks
    or use "\" to escape the white space and special symbols.

    Keywords and values are case dependent. "Key", "key", and "KEY"  would
    be three different keywords.

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

    -debug enable debug printout

    -help print usage instructions

    -verbose
    print detailed information about the image

MAGICK SCRIPTING LANGUAGE
    The Magick Scripting Language  (MSL) presently defines the following
    elements and their attributes:

     <image>

    .in 20 Define a new image object. </image>  destroys it.
    Because of this, if you wish to reference multiple "subim-
    ages" (aka pages or layers), you can embed one image ele-
    ment inside of another. For example:

   <image>
   <read filename="input.png" />
   <get width="base-width" height="base-height" />
   <image height="base-height" width="base-width">
   <image />
   <write filename="output.mng" />
   </image>

   <image size="400x400" />

     <group>

    .in  20 Define a new group of image objects. By default,
    images are only valid for the life of their <image>ele-
    ment.

   <image>  -- creates the image
   .....  -- do stuff with it
   </image> -- dispose of the image

    However, in a group, all images in that group will stay
    around for the life of the group:

   <group>     -- start a group
     <image>    -- create an image
     ....    -- do stuff
     </image>    -- NOOP
     <image>     -- create another
    image
     ....    -- do more stuff
     </image>    -- NOOP
     <write filename="image.mng" /> -- output
   </group>     -- dispose of both
    images

     <read>

    .in 20 Read a new image from a disk file.

   <read filename="image.gif" />

    To read two images use

   <read filename="image.gif" />
   <read filename="image.png />

     <write>

    .in 20 Write the image(s) to disk, either as a single mul-
    tiple-image file or multiple ones if necessary.

    <write filename=image.tiff" />
     <get>

    .in 20 Get any attribute recognized by PerlMagick's GetAt-
    tribute() and stores it as an image  attribute for  later
    use. Currently only width and height are supported.

   <get width="base-width" height="base-height" />
   <print output="Image size is  %[base-width]x%[base-
    height].\n" />

     <set>

    .in 20 background,  bordercolor, clip-mask, colorspace,
    density, magick, mattecolor, opacity. Set an attribute
    recognized by PerlMagick's GetAttribute().
