Question: Download QR code as an image #117

Closed charindukavishan closed 3 years ago

charindukavishan commented 3 years ago

Is there an API for download QR code as an image in this library?

Cordobo commented 3 years ago

Hi @charindukavishan

thanks for your question. Could you let me know

1) what's the purpose of downloading the image and 2) how's the users process to download the website/app, e.g. clicking on the image or having a separate button "download as image"? 3) what do you as a developer expect from the API?

  1. I want to print the QR code image
  2. Yes. I need to download the QR code image by clicking a separate button
  3. I expect a function for download the QR code as an image file (png/jpg)

Directly download is not available, but you can achieve it using file saver.

this package creates the QR code inside the canvas. so you can

  1. get the canvas element
  2. convert it to blob
  3. use file saver to save the file
