Description
Transforms and returns a specified vector from the absolute perspective to the local perspective.
Use AbsoluteToLocalVector to get the transposed coordinates of a vector from the absolute context to the local context of the current control. The absolute context for a control is the parent form area, and the local context is the control area.
P
is the vector to be transformed.
AbsoluteToLocalVector returns the transformed vector.
To have the inverse effect over a point, use LocalToAbsoluteVector.
