Sets the scale of a map.
SetScale(string map_name, real scale_value)
| Argument | Contents |
|---|---|
| map_name | The map whose scale is set |
| scale_value | The denominator of the scale when expressed as a ratio |
SetScale() does not affect the center of the map.
The map is not drawn at the new scale until the next call to RedrawMap() or until the map window is uncovered and needs to be redrawn.
If the map name argument is null, SetScale() changes the scale of the current map.
SetScale(null, 10000) // Sets map scale to 1:10,000
SetScale("My Map", 250000) // Sets map scale to 1:250,000
