Get Started

• Install svg.resize.js using bower:

    bower install svg.resize.js
  

• Include the script after svg.js and svg.select.js into your page

    <script src="svg.js"></script>
    <script src="svg.select.js"></script>
    <script src="svg.resize.js"></script>
  

• Select a rectangle and make it resizeable:

    <div id="myDrawing"></div>
  
    var drawing = new SVG('myDrawing').size(500, 500);
    drawing.rect(50,50).selectize().resize()
  

Usage

Activate resizing

var draw = SVG('drawing');
var rect = draw.rect(100,100);
rect.selectize().resize();

Deactivate resizing

rect.resize('stop');

Keep element within constrained box

var draw = SVG('drawing');
var rect = draw.rect(100, 100);
var opt = {
	constraint: {
		minX: 0,
		minY: 0,
		maxX: 200,
		maxY: 300
	}
};
rect.selectize().resize(opt)

Set minimum size

var draw = SVG('drawing');
var rect = draw.rect(100, 100);
var opt = {
	resizeLimits: {
		width: 20,
		height: 20,
	}
};
rect.selectize().resize(opt)

Options

• snapToGrid: Snaps the shape to a virtual grid while resizing (default 1)
• snapToAngle: Snaps to an angle when rotating (default 0.1)
• constraint: Keep element within constrained box (see usage above); The box snaps to the grid defined by snapToGrid.
• resizeLimits: Keep element with minimum size (default { width: 0, height: 0 })
• saveAspectRatio: Save aspect ratio of the element while resizing with left-top, left-bottom, right-top, right-bottom points.
