setcolor

Sets the current drawing color using the palette.

Defined in header <graphics.h>

Syntax

#include <graphics.h>
void far setcolor(int color);

Portability

Remarks

setcolor sets the current drawing color to color, which can range from 0 to getmaxcolor.

The current drawing color is the value to which pixels are set when lines, and so on are drawn. The following tables show the drawing colors available for the CGA and EGA, respectively.

Constantassigned to colornumber (pixel value) Palette

You select a drawing color by passing either the color number itself or the equivalent symbolic name to setcolor. For example, in CGACO mode, the palette contains four colors: the background color, light green, light red, and yellow. In this mode, either setcolor(3) or setcolor(CGA_YELLOW) selects a drawing color of yellow.

Return value

None.

   int gdriver = EGA, gmode = EGAHI, errorcode;
   int color, maxcolor, x, y;
   char msg[80];
   /* initialize graphics and local variables */
   initgraph(&gdriver, &gmode, "");

   /* read result of initialization */
   errorcode = graphresult();
   if (errorcode != grOk)    /* an error occurred */

      printf("Press any key to halt:");
      getchO ;
      exit(l);               /* terminate with an error code  */

   /* maximum color index supported */
   maxcolor = getmaxcolor();
   /* for centering text messages */
   settextjustify(CENTER„TEXT, CENTER_TEXT);
   X = getmaxx() / 2;
   y = getmaxy() / 2;
   /* loop through the available colors */
   for (color=l; color<=maxcolor; color++) {
      cleardevice();         /* clear the screen */
      setcolor(color);       /* select new background color */

      /* output a messsage */
   sprintf(msg, "Color: %d", color)
   outtextxy(x, y, msg);

/* clean up */
