Displaying Line Drawings 10.5.
dlpdfcontentarcto
This is an implementation of the PostScript arcto command, included as a
convenience to output drivers which currently support PostScript.
• The first two parameters are the ASFixed values of the (X,Y) position of the Line
Start.
• The third is the ASFixed value of the Radius of the Arc Segment.
• The fourth and fifth are the ASFixed values of the (X,Y) position of the
Intersection.
• The sixth and seventh are the ASFixed value of the (X,Y) position of the Line
End.
NOTE: This implementation will draw the line segment from the end of the arc to
the end position, which would not be drawn in PostScript.
dlpdfcontentpieslice
This method was included as a convenience operator for the construction of pie
charts.
• The first two parameters are the ASFixed values for (X,Y) of the center of the pie
the slice is taken from.
• The third is the ASFixed value for the Diameter of the pie slice.
• The fourth and fifth are the Start Angle and End Angle, in degrees, of the pie
slice.
The angles are counter-clockwise from right. The arc of the pie will be drawn counterclockwise.
If the angles are coincident, a full circle will be drawn.
dlpdfcontentpieslicen
This is identical to dlpdfcontentpieslice above, except that the arc will be
drawn clockwise from the Start Angle to the End Angle.
