问题 I want to put image on canvas. initially I used image as background. But whenever I convert canvas to image, background image is not getting copied. Hence I tried to draw image on canvas. I am choosing image from device image gallery. Storing the image url as string and passing to next component. I checked, able to get the value. Please see below code and let me know what I did wrong. 1. HTML <canvas no-bounce id="canvas" (touchstart)='handleStart($event)' (touchmove)='handleMove($event)'
