<p>
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:</p>

<pre>
    <?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>
</pre>
<p>
invoked with</p>
<pre>
    gm conjure -dimensions 400x400 incantation.msl
</pre>
<p>
All operations will closely follow the key/value pairs defined in
PerlMagick, unless otherwise noted.</p>
</sect>
<back>
<sect NAME="conj-opti">Options
<p>
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.</p>
<p>
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
geometry="%[dimensions]" or as a part of a string such as
filename="%[basename].png".</p>
<p>
The keyword can be any string except for the following reserved
strings (in any upper, lower, or mixed case variant): <s>debug</s>,
<s>help</s>, and <s>verbose</s>, whose usage is described below.</p>

<p>
The value can be any string.  If
either the keyword or the value contains 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.
<p>
Keywords and values are case dependent.  "Key",
"key",
and "KEY" would
be three different keywords.</p>
<p>
For a more detailed description of each option, see
<gm>
Options, above.

<p>
The Magick Scripting Language (MSL) presently defines the following
elements and their attributes:</p>

<dl>
<dt><image></dt>
<dd>background, color, id, size</dd>
<dd>
Define a new image object.  <s></image></s> destroys it. Because of
this, if you wish to reference multiple "subimages" (aka pages or
layers), you can embed one <s>image</s> element inside of another. For
example:
</dd>
<dd>
<pre>
    <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>
</pre>
</dd>
<dd>
<pre>
    <image size="400x400" />
</pre>
</dd>


<dt><group></dt>
<dd>
Define a new group of image objects.  By default, images are only
valid for the life of their <s><image></s>element.
</dd>
<dd>
<pre>
    <image>   -- creates the image
    .....     -- do stuff with it
    </image>  -- dispose of the image
</pre>
</dd>

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

<dd>
<pre>
    <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
</pre>
</dd>



<dt><read></dt>
    <dd>filename</dd>
<dd>
Read a new image from a disk file.
</dd>
<dd>
<pre>
    <read filename="image.gif" />
</pre>
</dd>
<dd>
To read two images use
</dd>
<dd>
<pre>
    <read filename="image.gif" />
    <read filename="image.png />
</pre>
</dd>
<dt><write></dt>
    <dd>filename</dd>
<dd>Write the image(s) to disk, either as
a single multiple-image file or multiple ones if necessary.
</dd>
<dd>
<pre>
     <write filename=image.tiff" />
</pre>
<dt><get></dt>
<dd>Get any attribute recognized by
PerlMagick's GetAttribute() and stores it as an image attribute for later
use. Currently only <i>width</i> and <i>height</i> are supported.</dd>

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

<dt><set></dt>
<dd>background, bordercolor, clip-mask, colorspace, density,
magick, mattecolor, opacity.  Set an attribute recognized by
PerlMagick's GetAttribute().</dd>

<dt><profile></dt>
    <dd>[profilename]</dd>
<dd>
Read one or more IPTC, ICC or generic profiles from file and assign to image
</dd>
<dd>
<pre>
    <profile iptc="profile.iptc" generic="generic.dat" />
</pre>
</dd>
<dd>
To remove a specified profile use "!" as the filename eg
</dd>
<dd>
<pre>
    <profile icm="!" iptc="profile.iptc" />
</pre>
</dd>
