dlpdfpathaddrect
This method will draw a rectangle. The first two parameters specify the (X,Y) position
Concepts and Facilities: Guide to the DL Pager Composition System
of a corner, and the next two specify the width and depth of the rectangle. A
positive width will draw to the right, and a positive depth will draw upward.
Current position need not be set before this method is called, and current position will
be set to the specified (X,Y) position after it is used.
dlpdfpathaddclose
This method will append a straight line segment from the current position to the start
of the first element in the path. If a current position is not set, it will have no effect.
Following this method, the current position will be unset.
NOTE: This does not need to be the last segment of a path. Additional, disjoint
segments may be set.
dlpdfcontentdrawpath
This method is used to add a drawn path to content.
• Its first element is the DLPDFCONTENT onto which this path is to be drawn.
• Its second parameter is the DLPDFPATH structure to be drawn.
• Its third parameter is a pointer to a PDEGraphicState structure. This structure
contains definitions of colors to be applied, and line sizes and parameters to be used
when drawing a path.
