- <h1>Configuring Annotation Icons</h1>
-
- <h2>User-definable icons by Annotation type (aka "dynamic icons")</h2>
-
- <p>
- As of Release 6.2, the icon used to mark the location of
- an annotation within an annotated document may be changed
- by the user.</p>
-
- <p>
- In release 6.2 the icon that denotes an annotation is chosen
- as a property of the annotation type. By including an RDF
- property of each annotation type you wish to use, you select
- the icon associated with annotations of that type.</p>
-
- <p>
- The sample configuration that is shipped with release 6.2
- associates the following icons:</p>

- The property name for adding annotation icons is
- <a href="http://www.w3.org/2001/10/typeIcon#usesIcon"
- >http://www.w3.org/2001/10/typeIcon#usesIcon</a>.
- For instance, to specify an icon named
- file:///home/question-icon.jpg for annotations that have type
- <a href="http://www.w3.org/2000/10/annotationType#Question"
- >http://www.w3.org/2000/10/annotationType#Question</a>
- you would enter the following RDF/XML into a file that
- Amaya reads at startup is:</p>
-
- <pre>
- <rdf:RDF
- xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
- xmlns:i = "http://www.w3.org/2001/10/typeIcon#">
- <rdf:Description rdf:about="http://www.w3.org/2000/10/annotationType#Question">
- <i:usesIcon rdf:resource="file:///home/question-icon.jpg" />
- </rdf:Description>
- </rdf:RDF>
- </pre>
-
- <p>
- The simplest way to get such RDF loaded into Amaya at startup is
- to include the file in the config/annot.schemas file in the Amaya
- program directory. In order to preserve this file so that it will
- not be overwritten when you install a new version of Amaya, you
- should copy the config/annot.schemas file into your personal
- Amaya home directory; ~/.amaya/annot.schemas (on Unix systems)
- or /winnt/profiles/<username>/amaya/annot.schemas (on Microsoft
- Windows systems). You may list as many RDF files as you want
- in annot.schemas. See the comments in the file included in the
- Amaya kit for more details.</p>
-
- <p>
- Release 6.2 includes a sample file named "typeIcon.rdf" that
- declares unique icons for each annotation type declared in the
- <a href="http://www.w3.org/2000/10/annotationType#"
- >http://www.w3.org/2000/10/annotationType#</a> namespace. To experiment
- with user-defined icons, it may be easiest to copy this typeIcon.rdf
- into another directory and modify it. Copy annot.schemas to your
- Amaya home directory and change the line near the end to point to
- your revised icon definition file.</p>
-
- <p>
- To revert to the previous behavior prior to release 6.2, edit
- the config/annot.schemas in the Amaya installation directory and
- add a comment character ("#") at the beginning of the line near
- the end that refers to typeIcon.rdf:</p>
-
- <pre>
- #user-defined icons
- #http://www.w3.org/2001/10/typeIcon# $THOTDIR/config/typeIcon.rdf
- </pre>
-
- <p>
- Amaya supports JPEG, PNG, and GIF bitmap graphics formats for icon
- images. In release 6.2 the icon URI may only be a file: URI; that
- is, the icon must appear in a local or mounted directory to Amaya.
- Two special forms of non-file: URIs are supported. If the file path
- name starts with "$THOTDIR" or "$APP_HOME" then the corresponding
- Amaya installation directory or personal Amaya home directory is
- substituted into the pathname.</p>
