   integer,intent(in)          :: row
   integer,intent(in)          :: column
   integer,intent(in),optional :: indx

DESCRIPTION

Directly set a pixel to the current or specified color index. The ROW and COLUMN start at 1.

OPTIONS

ROW row number in P_pixel to set
0 < ROW < size(P_pixel,dim=1)-1.

COLUMN column number in P_pixel to set
0 < COLUMN < size(P_pixel,dim=2)-1.

INDX color index to set pixel array to. Optional

EXAMPLE

Sample program

   program demo_pixel
   use :: M_pixel
   implicit none
      call prefsize(10,10) ! set up drawing surface
      call mapcolor(0,255,255,255)
      call mapcolor(1,255,000,000)
      call mapcolor(2,255,255,000)
      call mapcolor(3,255,000,255)
      call mapcolor(4,000,255,255)
      call mapcolor(5,000,255,000)
      call mapcolor(6,000,000,255)
      call mapcolor(7,000,000,000)
      call vinit()
      call color(0)
      call clear()
      call color(1)
      call pixel(1,1)
      call color(3)
      call pixel(3,3)
      call pixel(5,5,5)
      call print_ascii()
      call vexit()
   end program demo_pixel
