Detailed Description

Generates an HTML image map and an image from a scene graph.

This action generates an image file and an HTML file containing the image (<IMG>) and image map (<MAP>) tags. Each region of the image map will have a URL associated with it.

With HTML, image maps allow to specify regions of an image and assign a specific action to each region (a link can be associated to each map). When the region is activated by the user, the action is executed.

Each region of the image is determined by a subgraph which is under an SoWWWAnchor group node.

The HTML file generated contains, in the following order:

An image map tag that defines the regions (maps) corresponding to each subgraph that is under an SoWWWAnchor group node.

For each region, the associated link is the URL defined either by the SoWWWAnchor node.

An image tag that references the image generated by SoToHTMLAction.
