I have a canvas which is 800 * 400px used to do signature, and how can I resize the canvas and signature together?

ctx.scale method only resize the canvas but the painted content will disappear.

thx!

  • Maybe use zoom? https://css-tricks.com/almanac/properties/z/zoom/ Can you add some example code to try it on? –  Nov 16 '17 at 10:08
