graphic function ttg_line()
The Tool&Task graphic function ttg_line() draws a line between two points into the target bitmap (gTTG_Target:ttg_common). It uses the current definition of ttg_pen() and receives 4 numeric parameters.
The command ttg_line(0, 0, 0, 0) will set one pixel into the upper left corner.
Parameters:
1: X coord point 12: Y coord point 1
3: X coord point 2
4: Y coord point 2
