GRAPHIC ELLIPSE statement

Purpose

Draw an ellipse or a circle in the selected graphic target.

Syntax

GRAPHIC ELLIPSE (x1!, y1!) - (x2!, y2!) [, [rgbColor&] [,

[fillcolor&] [, [fillstyle&]]]]

Remarks

The graphic target must first be selected with GRAPHIC ATTACH. The Coordinates are specified in the same terms (pixels or dialog units) as the parent dialog (or world coordinates, if those were chosen with GRAPHIC SCALE). Line width can be set using GRAPHIC WIDTH. If line width is set to 1 (the default), the line style can be set with GRAPHIC STYLE. Because of the nature of an ellipse, which has no obvious beginning or end, GRAPHIC ELLIPSE neither uses, nor updates, the last point referenced (POS).

x1!, y1!

The upper left corner of the bounding rectangle.

x2!, y2!

The lower right corner of the bounding rectangle.

rgbColor&

Optional RGB color of the ellipse edge. If omitted (or -1), the edge color defaults to the current foreground color for the selected graphic window.

fillcolor&

Optional RGB color of the ellipse interior. If fillcolor& is omitted (or -2), the interior of the ellipse is not filled, allowing the background to show through. If fillcolor& is -1, the interior is painted with the same color as the edge. Otherwise, fillcolor& specifies the RGB color to be used.

fillstyle&

Optional fill style (pattern) to be used. If fillstyle& is omitted, the default fill style is solid (0). If a hatch pattern is chosen (1 to 6), the foreground color is specified by the fillcolor&, while the background is specified by the default background color for the selected graphic window. The optional fillstyle& may be:

0	Solid (default)
1	Horizontal Lines
2	Vertical Lines
3	Upward Diagonal Lines
4	Downward Diagonal Lines
5	Crossed Lines
6	Diagonal Crossed Lines
