6. Batch scaling shapes

        Batch scaling your shapes when needed.

    Although you can zoom in/zoom out all shapes anytime, but actually you may want to resize all the shapes as a specified x coordinate scale or y coordinate one. You may want to batch scale these all shapes under different x and y coordinates scale percentage. But how you can do this?

    Now we added a new scaleBy method for all AbstractShapes and its subclasses.

         Sample codes of a batch scaling.

public void scaleCurrentLayer(double xScale, double yScale){

//set a base point to up-left corner
JFPoint basePoint =new JFPoint(0,0);

//scale all shapes in current layer.
JFLayer layer =getDrawCanvas().getDrawPage().getCurrentLayer();
Iterator it =layer.getShapeList().getList().iterator();
while (it!=null && it.hasNext()){
AbstractShape shape=(AbstractShape)it.next();
shape.scaleBy(basePoint,xScale,yScale);
}

         Screenshot of this sample.

    Now you can take a look at the effects of this batch scaling method.

(Scale percentages for demonstration)
