How to draw colour vectors

Add background image to library
 
 Create a style for page with the image as background
 Create a vector style col=gold, width=2, currel=OC
 Create a vector style col=red, width=5, currel=OC, opacity=80
 Create a vector style col=maroon, width=9 currel=OL
 Create a line style col=blue, width=15, currel=CC, opacity=40;
 Create a line style col=green, width=15, currel=SC,  opacity=40
 
 Define a page named "pageName" with style "pageStyle"
 
 Set current position to X=240, Y=150
 Draw line1, 150 long angle of 30 with offset of 20
 Draw line2, 150 long angle of 60 with offset of 20
 Draw line3, 130 long angle of 90 with offset of 20
 Draw line4, 220 long angle of 135
 Draw line5 , 110 long angle of 225
 
 After loading show the page named "pageName"

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

STYLE(pageStyle, Page) { image = background; }
STYLE(drawStyle1, Draw) { type = Vector; col = gold; width = 2; currel=OC;}
STYLE(drawStyle2, Draw) { type = Vector; col = red; width = 5; currel=OC; opacity=80; }
STYLE(drawStyle3, Draw) { type = Vector; col = maroon; width = 9; currel=OC; opacity=80; }
STYLE(drawStyle4, Draw) { type = Vector; col = blue; width = 15; currel=CC; opacity=40; }
STYLE(drawStyle5, Draw) { type = Vector; col = green; width = 15; currel=SC; opacity=40; }

PAGE(pageName, pageStyle)
{
POSN(240, 150);
DRAW(line1, 150, 30, 20, drawStyle1);
DRAW(line2, 150, 60, 20, drawStyle2);
DRAW(line3, 130, 90, 20, drawStyle3);
DRAW(line4, 220, 135, drawStyle4, 240, 150);
DRAW(line5, 110, 225, drawStyle5, 240, 150);
}
SHOW(pageName);
