world.WindowArc
Draws an arc in a miniwindow
Prototype
long WindowArc(BSTR WindowName, long Left, long Top, long Right, long Bottom, long x1, long y1, long x2, long y2, long PenColour, long PenStyle, long PenWidth);
Description
This draws an arc from x1,y1 to x2,y2 inside the box (Left,Top,Right,Bottom) with the designated pen.
Note that changes to miniwindows will not become visible until the output window is redrawn. This happens when new (visible) lines arrive from the MUD, or if you call WindowShow, or Redraw.
Parameters:
WindowName - the name of an existing miniwindow.
Left, Top, Right, Bottom - describes the rectangle into which the arc must fit.
x1, y2 - the starting point for the arc - this point does not have to lie exactly on the arc.
x2, y2 - the ending point for the arc - this point does not have to lie exactly on the arc.
PenColour - the RGB colour for this pen
PenStyle - what style of pen to use:
0 - solid (an unbroken pen)
1 - dash: -------
2 - dot: .......
3 - dashdot: _._._._
4 - dashdotdot: _.._.._
5 - null (no pen)
6 - insideframe - a solid pen, drawn inside the shape
Also you can add into the style:
0x0000 - round ends (0 = the default)
0x0100 - square ends (256)
0x0200 - flat ends (512)
0x0000 - round joins (0 = the default)
0x1000 - bevel joins (4096)
0x2000 - miter joins (8192)
PenWidth - the width of the pen in pixels. For styles 1 to 4 only a width of 1 is valid.
For a particular shape, specify style 5 (no pen) if you only want to fill the shape, and not stroke it as well.

miniwin.pen_join_miter = 8192
-- how lines end (add this to the style)
