public bool ScaleFactorAtPoint(const ProjectedPoint
&point, ScalarValue &scale) const
Description
The ScaleFactorAtPoint method calculates the scale factor at the specified point. The scale factor of a point is the degree to which the scale of the map is distorted at the specified point. A scale factor of 1 indicates that the map scale is accurate at the specified point, while a scale factor greater than one indicates that a projected distance at that point is larger than the actual distance, and a scale factor less than one indicates that a projected distance at that point is smaller than the actual distance. This method takes two arguments, the first of which is the ProjectedPoint at which the scale factor should be calculated, and the second of which is the double value, passed by reference, that will hold the resulting scale factor. The method returns a boolean value indicating the success of the operation.
