I'm trying to scale an image proportionately to the canvas. I'm able to scale it with fixed width and height as so:
context.drawImage(imageObj, 0, 0, 100, 100) But I only want to resize the width and have the height resize proportionately. Something like the following:
context.drawImage(imageObj, 0, 0, 100, auto) I've looked everywhere I can think of and haven't seen if this is possible.

You can scale your canvas with content by "bouncing" the content off a temporary canvas while you resize the original canvas. This save+redraw process is necessary because canvas content is automatically cleared when you resize the canvas width or height.
context.drawImage(imageObj, 0, 0, 100, 100 * imageObj.height / imageObj.width) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
