clickable zoom region

I created a zoomed image (.png) and add it to the slide, made it invisible, then revealed it with a trigger I place on a zoom in icon image.

ZOOM IN

THE ZOOM IMAGE: edit the image state and create a "disabled" state. Then delete the image in the disabled state, and set the initial state to Disabled to make it invisible.  Place a zoom in icon or button in the corner of the area you want them to be able to zoom into and place a trigger on it.

THE TRIGGER: For the trigger I use:

Action: change the state of

Object: the zoomed image

To State: normal

When: user clicks

Object: the zoom in icon I placed on the slide

ZOOM OUT

TO ZOOM OUT: place a zoom out icon or button in the corner of the area you want them to be able to zoom out of and place a trigger on the icon.

THE TRIGGER:  For the trigger on the zoom out icon  I use:

Action: change the state of

Object: the zoomed image and the zoom out icon

To State: disabled (remember I deleted the image of these in their disabled states to create invisibility)

When: user clicks

Object: the zoom out icon image I placed on the slide
