@@dcode-software Question if I may? I have a jpg displayed on an html canvas, and I'm trying to use moveTo, and lineTo to draw on top of that image, but the image is overwriting the lineTo. I see it trying to draw the line, but it disappears as the jpg takes over, any thoughts ?
Was it for a whiteboard project 😊

Thanks for doing this video. but png saves in white and jpg saves in black. I want to keep the background color of the canvas that I assign. Any idea how to get around this?
It's because PNG usually supports transparent background but JPEG don't , you can set custom colors in background of canvas to get desired volor
