We can use the quadraticCurveTo method that comes with the canvas context object to draw a curve through n points. Then we can use it by writing: const points = [{ x: 1, y: 1 }, { x: 20, y: 30 }, { x: 30, y: 40 }, { x: 40, y: 20 }, { x: 50, y: 60 }] const canvas = document. querySelector('canvas') const ctx = canvas.
For drawing straight lines, use the lineTo() method. Draws a line from the current drawing position to the position specified by x and y . This method takes two arguments, x and y , which are the coordinates of the line's end point.
There are the following methods to draw a straight line on the canvas. beginPath(): This method is used to begin the path that we are going to draw. It does not take any arguments. moveTo(): This method takes two arguments which will be the starting point of any path.
I'm using <canvas> to capture user input in the form of a signature and am trying to figure out how to smooth the input from the mouse.
I think I need to process the user's mouse movements chunk by chunk and smooth each chunk, I'm not after super smoothing but any improvement on the jagged input would be good.
Thanks, Mark
