LVectorBase::GetCamera

#include "ltwrappr.h"

virtual L_INT LVectorBase::GetCamera(pVectorCamera)

/* pointer to a structure */

Gets the current camera values.

Parameter	Description
pVectorCamera	Pointer to a VECTORCAMERA structure to be updated with the current camera values.

Returns

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

Comments

This function will get the current viewing camera.

The camera is used with the view port to determine how the drawing will be projected into the destination DC when using LVectorBase::Paint.
