I have an inventory list on microsoft lists with a barcode column. The barcodes shows up as both image and number in Lists fine. I can click it and it previews in the browser as an image. However, I can't get that barcode image to show up in Power Apps. The image field in Power App allows me to set the Barcode column from Lists but it won't show the image.

Unfortunately I was unable to test this further on my end, but the resources below might be of help. The YouTube link shows a way in which you can display the barcode image by using the SP image URL as the input. The second link makes use of barcode APIs in which you can provide the barcode value and you receive the barcode image in return.
To do this, you will first need to retrieve the URL of the barcode image from the barcode column in your Microsoft Lists inventory. You can do this by using the LookUp function to find the row in your list that corresponds to the current item in your gallery, and then using the ThisItem function to retrieve the value of the barcode column for that row.
Once you have the URL of the barcode image, you can set the Image property of your Image control to that URL. Make sure to set the Image property to the result of the Concat function, which combines the URL with the image file extension (.png, .jpg, etc.) to create a valid image URL.
In this example, 'Barcode' is the name of your barcode column in Microsoft Lists. The Url property retrieves the URL of the barcode image, and the ?RenditionID=1 parameter ensures that the image is rendered in its original size.
LaurensM WarrenBelz JohnM86 Thanks for your comments. The youtube link LaurensM provided seems like the closest thing I could follow to get it to work. However, I am unsure of what to change the code to in my use case to get the result he has. He seems to be pulling the barcode image from lists and then from a form in power apps called "DataTable3". In my scenario, I am wanting to pull the barcode image directly from a Lists column called Barcodes. Which seems possible using the technique in the video. Any suggestions on what I would change this portion of the code to?
You will have to reference the SP list record's ID field of which you want to display the barcode image, within the YouTube video the users wants to view the barcode image of the selected item from the Data Table control.
I am also following similar approach but this approach works for me only when if any sharepoint instances open in the tab but then barcode shows but when i open my app in incognito mode where no sharepoint instances are open then I am not getting any barcode image displayed

Anyone using the Barby gem ( ) to generate and print barcodes? I'm generating and printing png barcode files and they are coming out fuzzy. Note that the generated PNG files look great, even when zooming way in on the bars, yet when it's printed the edges are fuzzy. I'm printing barcodes of the same size and format I got elsewhere on the same printer and they look nice and crisp.
Basically, define a read-only note for each individual with their name and an embedded image (ie media::image), and use relevant logic to only show the one who's id matches the userid captured from your barcode/QR code scanner. See -styling/
Yes, I had thought about instead making a long choice list with all the pictures and names (see -question-types/#select-widget-with-image-choices) and using a calculation to effectively programmatically select the option corresponding to the scanned id. But the issue is that it'll still show all the pictures (but only one will be selected).
You might need to customize the letter: there will be .png image files referenced in the XSL. For the fix, you will just need to prefix each PNG with "cid:" (for example: "Barcode.png" will become "cid:Barcode.png").
Here's what's happening:
For all of the barcode information, it is sent in the e-mail as image attachments. Most e-mail clients will read the XSL of the letter and know to embed these images in the body of the email. But some clients do not (which can often include printers), and the barcodes stay as attachments. Adding the 'cid' prefix as described above "forces" the images into the body

This barcode to image guide shows off how you can chain multiple Label LIVE features to achieve a dramatic improvement in workflow. Building off our previous Barcode Duplication guide, we take it a step further to show how you can scan a barcode and save a high DPI PNG image of that barcode's data, or something else entirely.
A Barcode Image API, takes a raw barcode value and converts it into a barcode image that can printed, added to labels, and scanned using a barcode scanner. The free barcode image API makes it easy to add the ability to generate barcodes to your applications using a single URL.
Note: some barcodes require a specific type of data. If you provide invalid data, the image returned will explain the issue, for example barcode.orcascan.com/?type=upca&data=hello produces:
The goal of this blog post is to demonstrate a basic implementation of barcode detection using computer vision and image processing techniques. My implementation of the algorithm is originally based loosely on this StackOverflow question. I have gone through the code and provided some updates and improvements to the original algorithm.
Then, we use the Scharr operator (specified using ksize = -1 ) to construct the gradient magnitude representation of the grayscale image in the horizontal and vertical directions on Lines 19-21.
From there, we subtract the y-gradient of the Scharr operator from the x-gradient of the Scharr operator on Lines 24 and 25. By performing this subtraction we are left with regions of the image that have high horizontal gradients and low vertical gradients.
Notice how the barcoded region of the image has been detected by our gradient operations. The next steps will be to filter out the noise in the image and focus solely on the barcode region.
Luckily, this is the easy part. On Lines 41-44 we simply find the largest contour in the image, which if we have done our image processing steps correctly, should correspond to the barcoded region.
