C++ (Cpp) PostScriptFreeDash Examples

Example #1

int main(int argc,char *argv[]) {

  struct PostScript *ps=NULL;
  struct PostScriptDash *dash=NULL;

  float p[3]={5,2,3};


  float wdt=400,hgt=400;
  float xoff=50,yoff=50;

  unsigned int fgcol=0xff000000;

  ps=PostScriptMake();
  PostScriptSetText(ps,stream,stdout);   
  PostScriptMakePlot(ps,xoff,yoff,wdt,hgt,0);

  dash=PostScriptMakeDash(p,0,3);

  
  PostScriptRectangle(ps,NULL,10,10,wdt-20,hgt-20,
                      0,fgcol,0,dash,NULL);

  PostScriptFreeDash(dash);

  

  PostScriptEndPlot(ps);
  return 0;
}
