Canvas undefined when using .getResult()

[edshen17]

Hello, I was playing around with the Twitter showcase and wanted to get the canvas from getResult(). However, it returns undefined.

Please check this fork. It's basically the same code, but I print the result in onChange().

I know that the documentation says that this example uses undocumented/unreleased features, but is there any way I can get the canvas, or the cropped image after zoom/movement? My end goal is to construct a blob with canvas.toBlob().

Thanks, Edwin.

Hello, @edshen17!

The props canvas is false, that's the reason why the canvas from getResult is undefined.

You can enable canvas, but in this case I recommend to get the result not on change, but on some action. For example, clicking the button continue.

See the second method of the getting result.

Thank you for the quick reply! It works now once I set canvas to false.

Ah yes, I was just trying to show that it was undefined since it was easy to do in the onChange method. Thanks again!
