Add Annotations to a Web Application

Prizm® Viewer provides robust support for annotating images:

Annotations for images on a local hard drive or network drive
Web-based annotations (supported by a Prizm Annotation Server)

Refer to the Annotations topic for details on working with annotations.

Only embedded TIFF and PDF annotations that map to Rectangle, Ellipse, Highlight, Line, Stamp, Text, Polyline, Polygon, and Freehand annotations will be loaded; all other annotation types are ignored.

When annotation-enabling a web application using Prizm Viewer, there are several items that need to be addressed:

Preferences for loading annotations from a web server
Preferences for support of Embedded PDF or TIFF files
Preferences for showing and/or editing annotations
Mappings for the annotation server(s)
Prizm Annotation Server is available

Setting Annotation Settings in a Web Application via HTML

In the Object/Embed tag, you can set the annotation settings: AnnotationServers, AnnotateFromInternet, AnnotateImportEmbedded, InitialShowAnnotations, InitialEditAnnotations, ShowAnnotations, and EditAnnotations.

Setting Annotation Settings in a Web Application via a List File

In the Prizm List File, you can set the annotation settings: AnnotationServers, AnnotateFromInternet, AnnotateImportEmbedded, InitialShowAnnotations, InitialEditAnnotations, ShowAnnotations, and EditAnnotations.

List File Example	Copy Code
<?xml version="1.0" encoding="utf-8"?> <PrizmViewerListFile AnnotateFromInternet=”true” AnnotateFromLocal=”false” AnnotateImportEmbedded=”false” InitialShowAnnotations=”false” InitialEditAnnotations=”true”> <AnnotationServerList> <AnnotationServer ImageHostName = http://InsertAnnotationHostName AnnotationServerURL= "/InserLocationOnHost/InsertServerName.aspx"/> </AnnotationServerList> <ImageFileList> <ImageFile FileURL="Ccitt.tif"/> <ImageFile FileURL="accuracy.pdf"/> </ImageFileList> </PrizmViewerListFile>

List File Example

Copy Code

<?xml version="1.0" encoding="utf-8"?>
<PrizmViewerListFile AnnotateFromInternet=”true” AnnotateFromLocal=”false” AnnotateImportEmbedded=”false” InitialShowAnnotations=”false” InitialEditAnnotations=”true”>
 <AnnotationServerList>
  <AnnotationServer ImageHostName = http://InsertAnnotationHostName
      AnnotationServerURL= "/InserLocationOnHost/InsertServerName.aspx"/>
 </AnnotationServerList>
<ImageFileList>
 <ImageFile FileURL="Ccitt.tif"/>  <ImageFile FileURL="accuracy.pdf"/>
</ImageFileList>
</PrizmViewerListFile>

The preference settings for annotations are also available as properties that can be set within the user preferences of the Prizm Viewer application. For more information on user preferences, see the Accusoft.PrizmViewer10.User.chm help file.

Prizm Annotation Server Availability

Before Prizm can load and save annotations for web-based images, you must provide an annotation server that Prizm Viewer uses to load and save annotations. The Prizm Annotation Server (SDK) includes two working sample versions of Prizm Annotation Server; one using ASP.NET technology, the other using Java Server Pages (JSP) technology. Go to the Accusoft website for information on downloading Prizm Annotation Server.

To help get you started, you can use one of the sample annotation servers included in the Prizm Annotation Server SDK. You only need to deploy one of the samples, modifying the appropriate configuration settings, and you are able to start annotating your web-based images. For more information about the sample annotation servers, see the Accusoft.PrizmViewer10.AnnotationServer.chm help file.
