GenerateQRCode | Custom QR code generation : general QR code

Case: I have a UISwitch button in view. When switch is off, the imageView will display a QRCode image generated from a string. When on, it will display a barcode image generated from string. I copied the QRCode and barcode generation functions from https://www.hackingwithswift.com/ and they are working fine.

The problem is the imageView displays the generated image only for the first time. When switching between QRCode and barcode, the imageView won't update anymore. I am 100% sure the UISwitch is working, the functions are called and returning the generated image. I have tested multiple times with break points and printing, the functions are not returning nil or empty images.

Here is QRCode generation code

I've been having a problem with updating a picture in python using Tkinter. This program is creating a QR code and is displaying it on the window. I have no idea how to update it when it changes, the file name stays the same it just changes. This is what activates the creation of a QR code

I want to mask a linear gradient with a Image initialized with Image(uiImage: ...). This kind of masking can clearly be done with Images initialized as systemName but when done with a UIImage there is no "masking" performed. Note that I need to use UIImage because my intention is to use a generated qrcode as the mask.

Correctly Masked sf image:

there I am facing a problem with barcode scanned data. I am creating an app where I need to get barcode scanned data into an HTML input element. The app works in development and the HTML input receive data from the barcode but in production, the HTML input does not receive data.

NOTE: i am using barcode to pc app for testing.

here is the code:

I am working on FrappeFramework 'ERPNext' customization.

I need to display QR code in sales invoice and also show it in print invoice.

Current flawed solution: Right now, I fetch an encoded string from server side. On the client side, I have a QR image HTML field as such:

Then in js, I use a js library ‘QRious’ to render HTML into that field and the QR code is displayed.

Describe the problem I am trying to call a JavaScript function but only when a if condition evaluates to True in Python. I'm working on a Music player project with Pygame and Eel, I want to call the JS function to change Song cover image automatically without a button click as the previous song ends, which am finding using pygame.mixer.music.get_busy() in python, during when I want to call the 'eel.fine()' but I'm sure why it's not working or how to get this done as am new to Eel

Expected When if condition becomes True function find should be called from python code i.e just want to change cover image when one song ends Code snippet(s) Here is some code that can be easily used to reproduce the problem or understand what I need help with. Note: I have removed most part of the code just to make to understand and have only added the portions that relate to the flow of the code what I need help with.

I'm practicing on how to generate a QR code based on the userID of the current user. And once the QR code of the specific user is scanned, it will display the account details of that user. I'm just practicing so I could be familiar with how this process works.

I have two classes, App and qrCode. The qrCode class returns a image of the qrcode based on the address provided in that classes state. The app class displays the qrcode component. In the method getSessionID, the app makes a request to the server, then should call updateQrCode to update the qrcode that is being shown.

How can I call the method updateQrCode from App.js? I can't instantiate a new QrCode, because that is not the instance that is being displayed.
