Portals in Pad++

Other Pad++ features

We have seen three example Pad++ applications. Now we will look at some other Pad++ features: portals, hyperlinks and magic lenses.

Portals - twists in Pad++ space

The Pad++ surface as an infinite zoomable space, with objects residing at specific x, y, zoom coordinates within that space.

Sometimes, however, you want to be able to compare two distant locations, or to look at a zoomed out view of a document together with a close up view.

Portals allow you to do this - they introduce 'holes' in the Pad++ surface through which you look onto other regions of the Pad++ surface, or in fact onto other Pad++ surfaces.
