[comp.windows.x] using XDraw to draw smooth curves

slm@cs.arizona.edu (Sandy Miller) (01/01/91)

I am trying to use the X10 XDraw routine to draw a smooth curve through
a series of points.  I have set the flags member of the Vertex argument
to VertexCurved for all but the first and last points.  But the segments
are still straight.  I am running X11R4, and including <X11/X10.h> and
linking with -loldX, as instructed in Appendix B of the Xlib Programming
Manual, Volumn One.  Should this work?  Has anyone else successfully
generated smooth curves using XDraw?  If so, could you give me some
hints as to what I might be doing wrong?

Thank you in advance,
