Image download from webviewer

[Lokesh_Samarth]

I want to download the image that I have viewed using the WebViewer URL in this block so that I can print it. Please provide the process for doing this. I have tried many times, but it's not working

From your URL, I see your QR creation server API is documented at
https://goqr.me/api/doc/

From your blocks, I see you expect a file to arrive within the same event where you call upon that server to make you a QR code image file.

There is no instantaneous response to a Web Get.

Let's take a moment to read the server docs, so we can we can see what kind of hoops they want you to jump through to get a file back.

Thanks for the reply. Actually, I need to download the QR code image. I need the process for this. I am getting error 908. I have tried all methods, but it’s not working. Can you help me with this?

I did a little doc reading, and reviewed your blocks, and I came to these conclusions:

• You don't need a WebViewer for this. The Web component is all you need.
• You have to set your Web component to expect a file response, not text.
• You need the Web event block that catches that incoming file, and grabs its file name, then sets up the Image component to show that image file.
• The text you send needs to be cleaned by one of the Web blocks that cleans text to allow it to ride along in a URL...Look for the URI-encoding block, as I recall.

If you export and post your aia file, that would facilitate testing.

Never mind, I whipped up my own test app for the board:

P.S. Thanks for the link to that nice web site.

In this, I need to download the generated QR code to my mobile for printing and after clicking the 'Scan QR Code' button, I want to read the printed QR code and display the result in a label. Can you please help me with this?

What kind of printer do you have connected to your phone, and what are its specifications for receiving and printing images?

[Lokesh_Samarth]

I am going to use a 3" portable thermal printer to print the QR code. It has an app and I will open the generated QR code in that app and print it.

[ABG]

I'm confused.

Why aren't you using the AI2 Scanner component?

Also, where is the BlueTooth component you would most likely use to communicate with a BlueTooth printer?
