dlpdfpatharray
This method will return a pointer to the first member of the array of ASFixed integers,
Concepts and Facilities: Guide to the DL Pager Composition System
which is the path.
Appending Line Segments to an Existing Path
The following methods append line segments to an existing path. Each of these
accepts a pointer to a path as the first parameter, and may or may not have additional
parameters describing the line segment to be built. These methods will return nothing,
but may raise an exception if the parameters are not properly formed.
dlpdfpathaddline
This method accepts three parameters:
• The first is a pointer to the path.
• The second is the absolute Xposition.
• The third is the absolute Yposition.
A line will be drawn from the current position to the specified new position. If the
current position is the same as the new position, no line segment will be added to the
path, and no notice will be given (Optimizing). The current position following this
command will be the specified position.
dlpdfpathaddliner
This methods accepts two parameters, the coordinates of the destination to draw to:
• The first is the distance from the current Xposition to the specified Xposition.
• The second is the distance from the current Yposition to the specified
Yposition.
A line will be drawn from the current position to the specified new position. If the
distances specified are both zero, no line segment will be added to the path and no
