dlpdfpathclear
This method will remove all content from an existing DLPDFPATH structure and
Concepts and Facilities: Guide to the DL Pager Composition System
restore it to the state it was in following the call to dlpdfpathcreate. It is included
to lower the overhead of creating many paths.
dlpdfpathdestroy
This method will destroy a DLPDFPATH structure and free all resources that it used.
dlpdfpathaddmove
This method will change the current position of a DLPDFPATH structure without
drawing a line. It may be used to establish the starting point of a path or to add a
disjunction to an existing path. It accepts two operators, an X and a Y position, as
ASFixed values. The current position following this method will be the specified
(X,Y) position.
dlpdfpathaddmover
This method also sets the current position, but sets it relative to the existing current
position. If there is no current position, this method will raise an exception
(genErrBadParm). This method accepts two parameters, an X and a Y displacement,
as ASFixed values. The current position following this method will reflect the
application of the X and Y displacements.
dlpdfpathaddline
This method draws a line from the current position to the position specified by its two
parameters, X and Y position as ASFixed values. If there is no current position
established, this method will raise an exception (genErrBadParm). The current
position following this method is the specified (X,Y) position.
