How to translate and rotate drawing in html5 without effecting another drawing.
When I try to translate first drawing and keep second drawing fixed second drawing also moves so I am trying to keep second drawing fixed at specified position and only translate first drawing when I change value of first translate function . My Code : - <!DOCTYPE html> <html> <body> <canvas id="myCanvas" width="300" height="150" style="border:1px solid #d3d3d3;"> Your browser does not support the HTML5 canvas tag. </canvas> <script> var c = document.getElementById("myCanvas"); var ctx = c.getContext("2d"); ctx.translate(10,10); ctx.fillRect(70,40,44,30); ctx.fillRect(10,10,40,30); </script> </body> </html>

<!DOCTYPE html>
<html>
<body>
<canvas id="myCanvas" width="300" height="150" style="border:1px solid #d3d3d3;">
Your browser does not support the HTML5 canvas tag.
</canvas>
<script>
var c = document.getElementById("myCanvas");
var ctx = c.getContext("2d");
var gtx = c.get context("2d");
ctx.translate(10,10);
ctx.fillRect(70,40,44,30);
gtx.fillRect(10,10,40,30);
</script>
</body>
</html>

hi! you can use save() and restore():
ctx.save(); // saves the context's transform/state
ctx.rotate(...);. // changes the transform
ctx.fillRect(...);
ctx.restore(); // restores last saved transf/state
ctx.fillRect(...); // works as if rotate was nvr called
