This draws an ellipse, rectangle, round rectangle, controlled by the Action parameter. The specified shape is filled with a previously-loaded image.

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.


WindowName - the name of an existing miniwindow.

Action - what sort of shape to draw, as follows:

1 = Ellipse
2 = Rectangle
3 = Round Rectangle

Left, Top, Right, Bottom - describes the rectangle into which the shape must fit.

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.

BrushColour - the colour used for drawing the background, when displaying monochrome bitmaps.

ImageId - an image id that you have loaded.

EllipseWidth, EllipseHeight - the dimensions of the ellipse in the corner of a round rectangle, if applicable.
