Ellipse

Ellipse:

    Ellipse(XPixelPosition, YPixelPosition, XRadius, YRadius [,Optional LineColour] )

Explanation:

Draws an unfilled ellipse on a GLCD centred at XPixelPosition, YPixelPosition with the given XRadius and YRadius.

The constant GLCD_PROTECTOVERRUN can be added to prevent ellipses from re-drawing at the screen edges. Ensure the GLCD_WIDTH and GLCD_HEIGHT constants are set correctly when using this additional constant.

Example:

    #include <glcd.h>

    Ellipse(63, 31, 20, 10)          ' <<< the Ellipse instruction

Key line: Ellipse(63, 31, 20, 10) — draws an ellipse centred at the middle of a 128x64 display, 40 pixels wide and 20 pixels tall (XRadius/YRadius are each half the full width/height).
