This app allows you to generate QR code image and Scan any QR image (& open in browser).

Core tech. of this app is using Google Chart API to generate image.

hi,

I'm new to power apps , pls suggest me the steps to create / Generate QR Code or bar code Image .

Hello @Gautham99 ,

In this app, I have used Google Charts API, https://developers.google.com/chart/infographics/docs/qr_codes

Simply set Image property as 

https://chart.googleapis.com/chart?cht=qr&chl=someVariable

where someVariable is defined by Text Input control.

Thanks,

Using this I developed my own layout but I'd like to save the QR Code that is generated. How would I do that?

Hello,
If you would like to save image file to some datasource, you need to use HTTP action in flow and Get image data from generated Url.
Or, you can use OneDrive for business connector with Action : “Upload file from URL”.
With this, temporary save image file to OneDrive and save appropriate directory/datasource 🙂
Thanks
Hiro

This is great and very useful!

Does anyone know how I may be able to print my generated QR code? I know you can print HTML text from PowerApps via PDF creation or via email to a specified user but printing images still seems to be near impossible, any suggestions welcomed!

For context I am essentially using powerapps to create an inventory list, the user adds items to a crate and the crate is given a unique ID. I am then using the QR generator to change the unique crate ID to a QR code which I would then like to print and physically stick on the crates ready for shipping.

Many thanks,

Jaz

Hi @Crossman,

Have you thought of inserting your QR code image into the HTML and generate the PDF to be printed out?

Hi, thanks for your reply.

I'm not sure I follow. PowerApps only allows for HTML text therefore when the bar code is added to the HTML no image is displayed and again with the PDF there is no image.

Unless I'm missing something?

Ok, here is the global process...

To generate a PDF file from an HTML containing images, you need to use a Flow. Call the Flow from PowerApps, sending your QR code image through the call (and other data if needed). Then in the Flow, build a string containing the needed HTML with your <img> tag that should look like this (convert your image data to Base64 first):

Still in the Flow, create an HTML file on a OneDrive and convert it to PDF using the adequate Flow operator.

Then, once you have the PDF file, I don't know how you want to print it...

Do you need more help on this? Is using the Flow process worth considering for your?
