s2slw

Set the linewidth in pixels.

Prototype

void s2slw(float width);

Description

Set the linewidth in pixels. The default is 1. Changing the line width affects lines and vector symbols. Unlike PGPLOT, text is not affected.

See Also

s2sch Set the character height in "arbitrary" units.

PGPLOT Equivalent

PGSLW

Code Example

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include "s2plot.h"

int main(int argc, char *argv[])
{
   float x[10], y[10], z[10];			/* Arrays of coordinate points */
   int N = 10;					/* Number of points */
   int Nl = 3;					/* Number of line widths */
   int i, j;					/* Loop variables */
   float width = 1;				/* Line width */

   srand48((long)time(NULL));			/* Seed random numbers */
   s2opend("/?",argc, argv);			/* Open the display */
   s2swin(-1.,1., -1.,1., -1.,1.);		/* Set the window coordinates */
   s2box("BCDET",0,0,"BCDET",0,0,"BCDET",0,0);	/* Draw coordinate box */

   for (j=0;j<Nl;j++) {
      for (i=0;i<N;i++) {
         x[i] = drand48()*2.0 - 1.0;		/* Random (x,y,z) coordinates */
         y[i] = drand48()*2.0 - 1.0;
         z[i] = drand48()*2.0 - 1.0;
      }

      s2sci((j%15)+1);				/* Set colour */
      width = 2.0*(float)(j+1);			/* Line width */
      s2slw(width);				/* Set line width */
      s2line(N, x, y, z);   			/* Draw the poly-line */
   }
   
   s2show(1);					/* Open the s2plot window */
   
   return 1;
}
