Fig. IV-5 Zoom/Pan Control Page
Options for zooming are by Rectangle and by Steps. Zoom by Rectangle allows the user to click and drag to define a rectangular area into which to zoom. Zooming by Steps allows the user to zoom by a certain percentage with each zoom. If Zoom by Steps is selected then a Default Step Size percentage must be entered. If the User Can Override option box is selected then the SICOM Display Module user can change the zoom step percentage at runtime.
The Pan Control options allow the SICOM Display Module user to pan by Center at Click (to center their map display at mouse click), by Drag with mouse drag, by Scroll using scrollbar, or by steps using Pan by Steps. If Pan by Steps is selected, then a Step Size percentage must be entered. The User Can Override option for Pan by Steps allows the Display Module user to change the step percentage at runtime.
Multiple types of zoom and pan control options may be selected.
