VEMap.SetShapesAccuracy Method

SetShapesAccuracy Method

Specifies the accuracy in converting shapes when the map style is changed to birdseye.

VEMap.SetShapesAccuracy(policy);

Parameters

Parameter	Description
policy	The VEShapeAccuracy Enumeration value specifying the accuracy in converting shapes.

Remarks

By default, shapes are not subject to increased accuracy representation when the map style is set to birdseye (the default accuracy is VEShapeAccuracy.None). Use this method to improve the accuracy of shapes when setting the map style to birdseye. By default, up to 50 shapes are converted at a time. To change this value, use the VEMap.SetShapesAccuracyRequestLimit Method.

The example uses the following custom images.
