===== getaspectration =====


====Syntax of getaspectration ==== 
 <code c>
#include <graphics.h>
void getaspectratio(int *xasp, int *yasp);
  </code>


==== Description of getaspectration ==== 
<code c>
The y aspect factor, *yasp, is normalized to 10,000. On all graphics
adapters except the VGA, *xasp (the x aspect factor) is less than *yasp
because the pixels are taller than they are wide. On the VGA, which has
"square" pixels, *xasp equals *yasp. In general, the relationship between
*yasp and *xasp can be stated as
*yasp = 10,000
*xasp <= 10,000
getaspectratio gets the values in *xasp and *yasp.

<code c>
/* getaspectratio example */

#include <graphics.h>

#include <stdio.h>
#include <conio.h>

   /* initialize graphics and local variables */
   initgraph(&gdriver, &gmode, "");

   /* read result of initialization */
   errorcode = graphresult();
   if (errorcode != grOk) {  /* an error occurred */
printf("Graphics error: %s\n", grapherrormsg(errorcode));

printf("Press any key to halt:");
getch();
exit(1);   /* terminate with an error code */
   }

   midx = getmaxx() / 2;
   midy = getmaxy() / 2;
   setcolor(getmaxcolor());

   /* get current aspect ratio settings */
   getaspectratio(&xasp, &yasp);

   /* draw normal circle */
   circle(midx, midy, 100);
   getch();

   /* draw wide circle */
   cleardevice();
   setaspectratio(xasp/2, yasp);
   circle(midx, midy, 100);
   getch();


   /* draw narrow circle */
   cleardevice();
   setaspectratio(xasp, yasp/2);
   circle(midx, midy, 100);

   /* clean up */
   getch();
   closegraph();
