Part of my app need to have a signature, I am able to have it signed on the screen and show in the image of the signature on the screen. But I need to put the signature to Cloudinary and can keep the link in variable. I can not do the upload to Cloudinary. Anyone can help how to do it? Thanks.

How are you having someone sign on the screen?

Are you able to assign that to an Image component?

If so, you can use the url from uploaded file block in the Files drawer:

Thanks for reply
So far, I have an image on the screen by using Canvas to drawn a signature. But it is 64 bits text. I don’t know how to make it as .jpg to send to Cloudinary?
