CHAPTER 5: Scripting with JavaScript Creating paths and shapes 50

//set stroked to true so we can see the path

myLine.stroked = true;

var newPoint = myLine.pathPoints.add();

newPoint.anchor = [220, 475];

//giving the direction points the same value as the

//anchor point creates a straight line segment

newPoint.leftDirection = newPoint.anchor;

newPoint.rightDirection = newPoint.anchor;

newPoint.pointType = PointType.CORNER;

var newPoint1 = myLine.pathPoints.add();

newPoint1.anchor = [375, 300];

newPoint1.leftDirection = newPoint1.anchor;

newPoint1.rightDirection = newPoint1.anchor;

newPoint1.pointType = PointType.CORNER;

var newPoint2 = myLine.pathPoints.add();

newPoint2.anchor = [220, 300];

//giving the direction points different values

//than the anchor point creates a curve

newPoint2.leftDirection =[180, 260];

newPoint2.rightDirection = [240, 320];

newPoint2.pointType = PointType.CORNER;

Combining path point types

The following script sample creates a path with three points:

var myDoc = app.activeDocument;

var myLine = myDoc.pathItems.add();

myLine.stroked = true;

myLine.setEntirePath( [[220, 475], [375, 300]]);

// Append another point to the line

var newPoint = myDoc.myLine.pathPoints.add();

newPoint.anchor = [220, 300];

newPoint.leftDirection = newPoint.anchor;

newPoint.rightDirection = newPoint.anchor;

newPoint.pointType = PointType.CORNER;

Shapes

To create a shape, use the pathItems method that corresponds to the shape’s name (like ellipse,

rectangle, or polygon), and use the parameters to specify shape’s position, size, and other information

like the number of sides in a polygon.

Remember:

X All measurements and page coordinates are processed as points by the scripting engine. For details,

see “

Measurement units” on page 30.

X x and y coordinates are measured from the bottom-left corner of the document, as indicated in the

Info panel in the Illustrator application. For details, see “

Page-item positioning and dimensions” on

page 30.
