stroke.space
Property; a string that specifies the spacing of a hatched line. This property is available only if the stroke.style property is set to hatched (see stroke.style). Acceptable values are "very close", "close", "distant", and "very distant".
The following example sets the space property to close for a stroke style of hatched:
var myStroke = fl.getDocumentDOM().getCustomStroke();
myStroke.style = "hatched";
myStroke.curve = "straight";
myStroke.space = "close";
myStroke.jiggle = "wild";
myStroke.rotate = "free";
myStroke.length = "slight";
myStroke.hatchThickness = "thin";
fl.getDocumentDOM().setCustomStroke(myStroke);
