LAnnLine::GetRotateAngle

#include "ltwrappr.h"

virtual L_INT LAnnLine::GetRotateAngle(pdAngle)

Gets the rotation angle for an annotation object.

Parameters

L_DOUBLE *pdAngle

Pointer to a double variable to be updated with the rotation angle.

Returns

Value	Meaning
SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

Call this function to get the rotation angle for a particular annotation object.

The angle is in radians, and uses the following convention.

The possible range of rotate values is (-Pi) ... (Pi).

A rotation in the clockwise direction is considered a positive rotation.

A rotation in the counter-clockwise direction is considered a negative rotation.

For example, if a rectangle is rotated 90 degrees in the counter clockwise direction, this function will get (-PI/2) for the rotation angle. If a rectangle is rotated 90 degrees in the clockwise direction, this function will get PI/2 for the rotation angle. If a rectangle is rotated 270 degrees in the counter clockwise direction, this is equivalent to 90 degrees in the clockwise direction so the rotation value returned is PI/2.
