Usage
Prepare a TEI/XML file like the following. The url value of <graphic> can specify a relative path from the file, an absolute path on your PC, or a URL published on the internet.
In the following example, the file digidepo_3437686_pn_null_9c48d89b-e2ec-4593-8d00-6fbc1d29d1bd.jpg stored in the same folder as the TEI/XML file is referenced.
<?xml version="1.0" ?>
<?xml-model href="http://www.tei-c.org/release/xml/tei/custom/schema/relaxng/tei_all.rng" type="application/xml" schematypens="http://relaxng.org/ns/structure/1.0"?>
<TEI xmlns="http://www.tei-c.org/ns/1.0">
<teiHeader>
<fileDesc>
<titleStmt>
<title>Sample</title>
</titleStmt>
<publicationStmt>
<ab/>
</publicationStmt>

<graphic url="digidepo_3437686_pn_null_9c48d89b-e2ec-4593-8d00-6fbc1d29d1bd.jpg"/>
</surface>

</TEI>
Clicking the “Author” button at the bottom of the screen displays the “Image Map Editor” as shown below. Refer to the video above to add annotations.

As a result, zone tags are automatically added as follows.
<?xml version="1.0" ?>
<?xml-model href="http://www.tei-c.org/release/xml/tei/custom/schema/relaxng/tei_all.rng" type="application/xml" schematypens="http://relaxng.org/ns/structure/1.0"?>
