Zoom_R
Return data about the current map view and levels of magnification
Syntax
Zoom_R <ScenarioPath> {DataOption} [<WinNumber>]
Description
The Zoom_R command returns information about the magnification of a Map's view, including how many zoom operations have been performed to get the current Map view and the current view's latitude and longitude values.
You can optionally enter <WinNumber> which is the number of the 2D window for which information will be returned. If not entered then the first 2D window will used.
{DataOption} can be:
| {DataOption} | <Parameters> and Description |
|---|---|
| Layers | Returns number of layers you're zoomed in, where 0 is the original view (not magnified) |
| Coordinates | Returns the current window coordinates as four real numbers: minimum latitude, maximum latitude, minimum longitude, and maximum longitude. |
| CoordAdjust | Returns the current window coordinates as four real numbers: minimum latitude, maximum latitude, minimum longitude, and maximum longitude, adjusted for the current map projection.
Coordinates are most accurate with flat projections (e.g. equidistant cylindrical, etc). |
All <Latitude> and <Longitude> values are returned in degrees.
Examples
To find out how many times you've zoomed in to get the current Map view in Map window #1:
Zoom_R * Layers 1
To get the latitude and longitude values for the current view in Map View #2:
Zoom_R * Coordinates
