How to draw arcs (ellipses with angle)

Create a library with the background image

Create a style for page with the image as background
Create a style for the ellipse1 - colour yellow, border orange with 5px width, alignment to bottom-left.
Create a style for the ellipse2 - colour springgreen, border saddlebrown - colours written with hex values
Create a style for the ellipse3 - without background colour - we get only the arc instead of piece of a circle, border red - width=7px, alignment to top-right.
Create a style for the ellipse4 - colour black,  without border - width=0px, alignment to center.

Define a page named "pageName" with style "pageStyle"
Set current position to X=10px, Y=260px
Draw the piece of circle we have to use here to two parameters for circle height and width equal to 150px (diameter), we use start angle=110 and arc angle=300
Set current position to X=240px, Y=236px
Draw the piece of ellipse width=200px, height=300px, start angle=330, arc angle=100
Draw arc named "ellipse3" - only border without background colour
Draw small black circle without border (Pacman eye)

After loading show the page named "pageName"

LIB(background,"SDHC/bground.png");

STYLE(pageStyle, Page) { image = background; }
STYLE(drawStyle1, Draw) { type = Ellipse; back = yellow; col = orange; width = 5; currel=BL; }
STYLE(drawStyle2, Draw) { type = Ellipse; back = \\00FF7F; col = \\8B4513; width = 3; currel=CC; }
STYLE(drawStyle3, Draw) { type = Ellipse; col = red; width = 7; currel=TR; }
STYLE(drawStyle4, Draw) { type = Ellipse; back = black; col = white; width = 0;currel=CC; }

PAGE(pageName, pageStyle)
{
POSN(10, 260);
DRAW(ellipse1, 150, 150, 110, 300, drawStyle1);
POSN(240, 236);
DRAW(ellipse2, 200, 300, 330, 100, drawStyle2);
DRAW(ellipse3, 100, 150, 200, 240, drawStyle3, 460, 100);
POSN(90, 150);
DRAW(ellipse4, 15, drawStyle4);
}
SHOW(pageName);
