const RECT *pViewport;

/* pointer to a structure */

Comments

Use this function to set the view port associated with a vector.

If the vector is attached to a window, you must call this function when processing WM_SIZE messages, since the VECTOR library needs to know when the window size has changed (DirectX), or when the double buffer mode is selected in the current VECTOR engine.

This function, along with LVectorBase::SetCamera are required to complete the projection process from a vector image onto a 2D surface.
