fg_drawlinep


Usage

   #include <fg.h>
   void far fg_drawline(fg_color_t color, int mode, int mask, int
                        line_type, fg_const_pline_t line);
   void fg_drawlinep(fg_color_t color, int mode, int mask, int
                     line_type, fg_const_pline_t line);

Description

   Draws a line from (x1,y1) to (x2,y2) using the indicated line type,
   color, mode and mask. The line must have been previously clipped to
   fg.displaybox.

   fg_drawlinep differs from fg_drawline in that the end points of the line
   will be drawn regardless of the line type.

Example 


   {
   fg_line_t line_to_draw;
   /* A line from the upper left corner to the lower */
   /* right corner of the display.                   */
       line_to_draw [FG_X1] = fg.displaybox [FG_X2];
       line_to_draw [FG_Y1] = fg.displaybox [FG_Y1];
       line_to_draw [FG_X2] = fg.displaybox [FG_X1];
       line_to_draw [FG_Y2] = fg.displaybox [FG_Y2];
       fg_drawline(FG_WHITE, FG_MODE_SET, ~0,
           FG_LINE_SOLID, line_to_draw);
   }
