8.6 DLI Implementation and Reference Guide
dlpdfcontentpath
This procedure will mark a path within the content. The path is specified as an array of ASFixed values,
pointed to by Path, with PathLen entries in the array. This is in all ways the same path as would be used
by the Adobe PDF Library path operators. Such a path may be created manually or by use of the Edit
Layer of the Adobe PDF Library. If created with the Adobe PDF Library, the pointer returned by
PDEPathGetData is sufficient for this call.
NOTE: The length returned by that call is the number of entries in the list, not the
size in bytes of the list.
dlpdfcontentrect
This procedure marks a rectangle in the content. It will be located such that its lower left hand corner is at
(X,Y); it will be Width wide, and Height high. Width and Height may not be specified as zero but may
be specified as negative numbers, which results in flopping the rectangle.
dlpdfcontentline
This procedure will mark a line in the content. The line will extend from (X1,Y1) to (X2,Y2).
dlpdfcontentarc
This procedure is included as an aid in transitioning from PostScript to PDF. It will draw an arc centered
at (X1, Y1), at a radius of Radius, from Angle1 to Angle2, counter-clockwise, where the angles are
considered to be in degrees.
dlpdfcontentarcn
This procedure is included as an aid in transitioning from PostScript to PDF. It will draw an arc centered
at (X1, Y1), at a radius of Radius, from Angle1 to Angle2, clockwise, where the angles are considered
to be in degrees.
dlpdfcontentarcto
This is a convenience method to mimic the PostScript ArcTo operator. It will locate the intersections of
the line (X1,Y1)->(Xint, Yint), and (X2,Y2)->(Xint, Yint), and draw an arc of the specified radius
tangent to those two lines. The line segment from (X1,Y1) to the arc will be drawn. Unlike the PostScript
ArcTo operator, the segment from the tangent to (X2,Y2) will also be drawn.
