7.4.18 Oval
Similar to an arc ( section 7.4.20 ) with an arc angle of 360 degrees, but arcs cannot be fi lled,
If the height and width of the oval are de fi ned in the default ‘percentage units’, then entering equal values for
height and width will result in an oval with the same aspect ratio as that of the screen, not a circle as might be
expected. Because the screen height is approximately 2/3 the width, the oval height should be 3/2 its width
to produce a circle. (The actual height/width ratio = 0.669).
7.4.19 Line
This causes a straight line of user-de fi nable thickness to be drawn between the points (X position; Y position)
and (X po width; Y po height)
Notes:
1 Y increases downwards; X increases rightwards
2 Height = 2/3 width if measuring in percent
X position;

EXAMPLE
To draw an approximation to a St.Andrew’s cross (saltire):
Access the component property editor page as described in
section 7.2.3 :
Select Advanced Edit level , then in the component property editor page
1. touch the ‘Add’ key at the top of the screen. In the ‘List of Component types’ page, press ‘Line’, ‘Add’,
‘Line’, ‘Add’, then ‘Close’
2. In ‘main_1.2’ - set background colour to 6
4. In ‘line_2.3’ Set Width to 100, Height to 100. Set Foreground colour to 55 and Line thickness to 35
5. In ‘line_3.4’ - Set X position to 100, Width to -100, Height to 100. Set Foreground colour to 55 and Line
thickness to 35
6. Press ‘Save’, then ‘Close’.
Note: because of the thickness of the lines takes the corners beyond the display area, an error mes-
sage may appear in the ‘Last error’ fi eld for the lines : position maybe out of bounds. This should not
prevent the screen being drawn correctly.
