Parameter

Description

pViewport

Pointer to a RECT structure that contains data on the new view port.

Returns

SUCCESS

The function was successful.

< 1

An error occurred. Refer to Return Codes.

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 double buffer mode is selected.

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