NAME

       DPDRAW - Used to draw a curve when fractional coordinates are available and no smoothing is to be done.

SYNOPSIS

       CALL DPDRAW (XCPF,YCPF,IFVL)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_dpdraw (float xcpf, float ycpf, int ifvl);

DESCRIPTION

       XCPF        (an  input  expression  of type REAL) specifies the X coordinate of a point in the fractional
                   coordinate system.  Ignored when IFVL = 2.

       YCPF        (an input expression of type REAL) specifies the Y coordinate of a point  in  the  fractional
                   coordinate system.  Ignored when IFVL = 2.

       IFVL        (an  input expression of type INTEGER) indicates what type of call is being done: "0" implies
                   a "first-point" call, "1" implies a "vector" call, and "2" implies a "last-point" or "buffer-
                   flush" call.

C-BINDING DESCRIPTION

       The C-binding argument descriptions are the same as the FORTRAN argument descriptions.

USAGE

       Use "CALL DPDRAW(XCPF,YCPF,0)" to do a "pen-up" move to the first point in a sequence of points  defining
       a curve.

       Use "CALL DPDRAW(XCPF,YCPF,1)" to do "pen-down" moves to the second and following points in a sequence of
       points defining a curve.

       Use  "CALL DPDRAW(0.,0.,2) to terminate a sequence of calls, finish drawing the curve, and flush internal
       buffers.

EXAMPLES

       Use the ncargex command to see the following relevant examples: tdshpk.

ACCESS

       To use DPDRAW or c_dpdraw, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably  in
       that order.
