What is wrong in my code - wrong strokeStyle applied?

[eaglehopes]

Hi, I am preparing a canvas program. I prepared a code for drawing lines by below code :

 

 draw(g,x0,y0,x1,y1) {  // draw line on canvas
        g.save();
        g.strokeStyle = "red";
        g.lineWidth = 1;
        g.moveTo(x0,y0);
        g.lineTo(x1,y1);
        g.stroke();
        // go back to origin 0,0 coordinates
        gotoOrigin();
        g.restore();
}

Although I used save() and restore() methods above, after this method, all strokes become red eventhough I explicitly changed strokeStyle to "#000000". I need some help about what is my mistake? Thanks.

You need to use beginPath() before you start to draw something.  Add a call to beginPath after you save the context.
