I wish to know if a QR code can be generated from an image input, like how one can generate QR code from a text input. So that, when I scan the QR code, I should be able to get the image as the scan result.
Can someone please let me know if this is possible?
It would have to be either an incredibly small bitmap, or a link to the image hosted somewhere else. The map of a QR code expands depending on data size, and while I am unsure if there is a technical upper limit, there is almost assuredly a practical upper limit with camera resolution being unable to decipher the massive code.
