fg_fill

Usage

   #include <fg.h>
   void far fg_fill(fg_coord_t x, fg_coord_t y, fg_color_t
                    fillcolor, fg_color_t boundary);

Description


   fg_fill does a boundary fill. It starts at (x,y) and draws pixels with
   fillcolor in the left, right, up and down directions until pixels with
   color boundary are encountered.

   fg_fill is recursive in nature, and for complex fills it requires an
   arbitrarily large amount of memory to store the recursion data. fg_fill
   does dynamic memory allocation as required, so it does not suffer from
   stack overflows or require the amount of memory needed to be specified in
   advance. If it does run out of memory it will simply terminate without
   completing the fill.

Example 

   /*
       fill an area in green, as bounded by white starting
       at coords 100,100
   */
   fg_fill(100, 100, FG_GREEN, FG_WHITE);
