LSL: string osDrawEllipse( string drawList, integer width, integer height )
C#: string osDrawEllipse( string drawList, int width, int height )

Appends an Ellipse drawing command to the string provided in drawList and returns the result.

The ellipse is drawn with the current pen size and color, with the specified width and height (in pixels), centered on a point which is (width/2) pixels to the right of the pen's current X position, and (height/2) pixels below the pen's current Y position. After the ellipse is drawn, the width and height values are added to the pen's X and Y position, respectively.

Example:

// Example of osDrawEllipse
default
{
    state_entry()
    {
        string CommandList = ""; // Storage for our drawing commands
 
        CommandList = osSetPenSize( CommandList, 3 );         // Set the pen width to 3 pixels
        CommandList = osSetPenColour( CommandList, "Blue" );  // Set the pen color to blue
        CommandList = osMovePen( CommandList, 28, 78 );        // Upper left corner at <28,78>
        CommandList = osDrawEllipse( CommandList, 200, 100 ); // 200 pixels by 100 pixels
 
        // Now draw the ellipse
        osSetDynamicTextureData( "", "vector", CommandList, "width:256,height:256", 0 );
    }
}
