Image which is drawn on canvas, disappears when i try to draw a path on canvas

[Rishi Khandelwal]

Hello,

I tried to draw a path on a canvas. That canvas has a image drawn already . As i press mouse to draw a path, that image disappears.

I am not getting the way, how to do this ??

My scenario : image drawn on canvas , then i want to draw paths over the canvas.

Thank You

Look this code, it work's.

paper.install(window);

paper.setup('draw');

var tool = new Tool();

    

tool.minDistance = 10;

    

var backgroundImg = new Raster({

            source: 'images/myBackImg.jpg',

            position: view.center

        });

var path;

tool.onMouseDown = function(event) {

// Create a new path and give it a stroke color:

path = new Path();

path.strokeColor = '#00000';

// Add a segment to the path where

// you clicked:

path.add(event.point);

}

tool.onMouseDrag = function(event) {

// Every drag event, add a segment

// to the path at the position of the mouse:

path.add(event.point);

}

Sounds like you're drawing directly to the canvas, using the Canvas API?

Paper.js will regularly clear the canvas, so you will loose things you're drawing outside of the Paper.js APi.
