Hyperlink View
Linking Overview
Hyperlinks provide a facility to associate one part of a presentation with an internal or external link to another (part of) a document.
Unlike HTML links, SMIL-based links also allow the activation and termination of links to be automatic (self-firing) and to be constrained by temporal attributes. The RealOne player also provides two HTML windows (the context and browser windows), which can contain Web content synchronized to the SMIL player content.
GRiNS provides a comprehensive management interface to maintain links in the presentation.
Link Management Commands
Hyperlinks source and destination can be visually created in the structured timeline, but they cannot be edited from that view. Modification and deletion of hyperlinks can only be done in the Hyperlink view. The view is divided into three sections: source anchor, links and destination anchors.
Anchor source
The left pane of the view identifies the source of the hyperlink. By default when creating a hyperlink, they are unnamed. But in this view, the anchors can be given names. Generally the anchor name should reflect the action that is desired by the hyperlink, rather than the name or the source or destination.
Links
The center section of the view that denotes a connection between source and destination. This link can be any of three directions, but that the most general usage is forward.
Anchor destination
The right pane of the view that shows the destination of the link. Both anchor panes do not actually show if a connection is present, but show a list of qualified anchors that may or not be connected.
The anchor destination pane also comes equipped with a toggle button that will filter the types of anchors by their used relation:
All internal
A full listing of all internal anchors, whether used or unused. Should a connected source and destination be selected in the appropriate panes, the Links pane will reflect that the connection exists.
Dangling
Show anchors that have no hyperlinks attached to them yet.
Follow global focus
Show anchors on the objects currently selected in the structure view.
All related anchors
This list shows only the existing connection to the anchor that is selected in the anchor source pane. If there are no connections from the source, this pane is empty.
No anchors, links only
Makes the right pane empty, but shows all links that originate from the anchor that is selected in the left pane.
External
Similar behavior to the All related anchors option except that it relates to external links only. This is used to create links to external documents such as other presentations or web-pages.
Keep list
Freezes the current contents of the pane.
Creating Anchors on Media
Anchors on media are created in the Layout view.
Links in SMIL can be associated with whole nodes or with ‘hot-spots’ that cover only part of a node. To create partial node anchors, open the layout view and select an object from the browser pane’s selection tree. Next, perform the following steps:
- Select Linking->Create Full Link Source and Edit...
- “Open” the image in the layout selector, and click on the anchor symbol.
- Using the drag handles in the layout view, create an anchor shape.
(You may also set anchor coordinates by hand under the More Anchor Setting property tab. See “Anchor Property Settings” on page 55.)
