122<h3>Percent Escape Handling</h3>
123
124<p>If you request a percent escape such as <code>%[key]</code> the setting
125is looked for in the following order until the first match has been
126found...</p>
127
128<ol>
129<li>Handle special prefixes such as 'artifact:' 'option:' 'exif:', or
130    'fx:'.  This includes and calculations and or globs of those prefixes such
131    as 'exif:*' or 'artifact:*' (see below).</li>
132
133<li>If <code>key</code> contains a glob pattern (but no known prefix)
134    search free-form properties table.</li>
135
136<li>If <code>key</code> is a special image 'attribute' name (see list
137    above) return the associated or calculated image attribute.</li>
138
139<li>Search for setting as a free-form 'property'</li>
140<li>Search for setting as a free-form 'artifact'</li>
141<li>Search for setting as a free-form 'option'</li>
142
143<li>Replace escape with empty string, and perhaps produce a warning.</li>
144</ol>
145
146<p>Remember, all long name forms of percent escapes are handled in a is case
147insensitive manner. </p>
148
149<p><b>As of IM v6.8.0-5</b> you can now access the Artifact and Option
150free-form string tables directly, allowing you to override the above sequence,
151and avoid accessing an attribute or property of the same name.</p>

367<p>Note that all single letter percent escapes can also be used using long
368form (from IM version 6.7.6-9, see next). For example <code>%[f]</code> is
369equivalent to the <code>%f</code> short form. </p>
370
371<p><b>WARNING</b>: short form percent escapes are NOT performed when the percent
372is after a number.  For example,  <code>10%x10</code> does not expand the
373<code>%x</code> as a percent escape.  If you specifically want to expand the
374'x', use the long form which overrides this special case. EG:
375<code>10%[x]10</code>. </p>

377<p>Also be warned that calculated attributes can take some time to generate,
378especially for large images.</p>

589<h3>Properties</h3>
590
591<p>All other long forms of percent escapes (not single letter long form) are
592handled in a case insensitive manner. Such escapes will will attempt to look
593up that name specific data sources. </p>
594
595<p>The primary search space (if not a specific attribute listed above) is
596a free-form property string.  Such strings are associated and saved with
597images, and are typically set using either the <a href="../www/command-line-options.html#set" >-set</a>
598CLI option (or API equivalent), or from special convenience options
599(such as <a href="../www/command-line-options.html#label"
600>-label</a>, <a href="../www/command-line-options.html#comment"
601>-comment</a>, <a href="../www/command-line-options.html#caption"
602>-caption</a>). </p>
603
604<p>These convenience options are globally saved (as 'global options' so thay can
605be set before images are read), and later are transfered to the property of
606individual images, only when they are read in. At that time any internal
607percent escape present is then handled. </p>
608
609<p>To change a property of an image already in memory, you need to use <a
610href="../www/command-line-options.html#set" >-set</a>.
611</p>
612
613<p>Note that properties, like attributes (and profiles), are saved with
614images when write, if the image file format allows. </p>
615
616
617<h3>Artifacts and Options</h3>
618
619<p>The previous percent escapes are associated with the primary Attributes and
620Properties. Which is the original and primary focus of such percent escapes.
621</p>
622
623<p>However there are many operational settings that are used by various
624ImageMagick operators that can be useful to set and later access.  These
625consist of per-image Artifacts, and Global options (associated with a list of
626images, typically the current image list).</p>
627
628<p>Note that the major difference between an artifact and a property is that
629artifacts, being an internal operational setting, is not saved with images (if
630such is possible). </p>
631
632<p>For example when you use <code>-define 'distort:viewport=100x100'</code> you
633are in fact generating a global option, which the <a href="../www/command-line-options.html#distort"
634>-distort</a> operator will use to modify its behavior (distorted output
635image 'view'). </p>
636
637<p>An Option is essentually a Artifact that has been stored globally as part
638of a list of images (specifically a 'Wand' of images). As such they are
639identical, in that a Option, is simply a global Artifact for all the
640associated images. </p>
641
642<p>As such you can use <code>-set 'option:distort:viewport' '100x100'</code> to
643achieve the same result of setting a Artifact for the disort operation to use.
644</p>
645
646<p><b>Internal Handling of a Global Option...</b></p>
647
648<p>The Core library ('MagickCore') does not generally directly understand
649Global Options. As such, continuing the previous example, the
650<code>DistortImages()</code> function only looks up an artifact to discover if
651a 'viewport' has been provided to it. </p>
652
653<p>How Global Options are used when a library function requests an Artifact is
654one of the key differences between IMv6 and IMv7.</p>
655
656<p>In <b>ImageMagick version 6</b>... before each operator, any global Options
657are copied to per-image Artifacts, for every image in the current image list.
658This allows various operators to find its operational 'defines' or Artifacts.
659</p>
660
661<p>In <b>ImageMagick version 7</b>... sets a link back to the global options
662data, so that if a specific per-image Artifact is not found , then it will
663look for a equivalent global Option for that image list.  directly.  This
664saves coping these free-form options into artifacts repeatally, and means you
665can now separately define a global option for a list, and a individual
666overriding artifact for a specific image in that list. </p>
667
668<p>Note that many API's that do not use Wands (PerlMagick for example using
669arrays of images rather than a Wand). In these API's you will not have Global
670Options, only per-image Artifacts. </p>
671
672<p>In summery a Global Option, if available, is equivalent to a per-image
673Artifact. </p>
674
675
676<h3>Glob-Pattern Listing of Properties, Artifacts and Options</h3>
677
678<p>The <var>setting</var> can contain a glob pattern. As such you can
679now list all free-form string properties, artifacts, and options, (but not
680specific image attributes) using...</p>
681
682<pre class="highlight"><code>convert ... \
683   -print "__Properties__\n%[*]" \
684   -print "__Artifacts__\n%[artifact:*]" \
685   -print "__Options__\n%[option:*]" \
686   ...
687</code></pre>
688
689<p> The format of glob patterns are very specific and as such is generally
690only used to list specific settings, such as when debugging, rather than being
691used for image processing use. </p>
692
693
694<h3>Calculated Percent Escape Prefixes</h3>
695
696<p>There are some special prefixes (before the first ':') which performs
697calculations based on the user provided string that follows that prefix.  For
698example you can do a numerical calculation use <code>%[fx:...]</code> to
699evaluate the given <a href="fx.html">FX</a> expressions:</p>
700
701<pre class="highlight"><code>%[fx:<var>expression</var>]
702</code></pre>
703
704<p>Use <code>pixel:</code> or <code>hex:</code> to evaluate a pixel color as defined by the <a
705href="fx.html">FX</a>
706expression:</p>
707
708<pre class="highlight"><code>%[pixel:<var>expression</var>]
709</code></pre>
710
711<h3>Specific Profile Percent Escape Prefixes</h3>
712
713<p>You can also use the following special formatting syntax to print EXIF
714mage meta-data that was included in the image read in:</p>
715
716<pre class="highlight"><code>%[EXIF:<var>tag</var>]
717</code></pre>
718
719<p>Choose <var>tag</var> from the following:</p>
720
721<pre class="pre-scrollable"><code>
722*  (print all EXIF tags, in keyword=data format)
723!  (print all EXIF tags, in tag_number data format)
724#hhhh (print data for EXIF tag #hhhh)
