HTML-Standalone QR-code generator for websites

Sometimes you need a QR-code generator in your website (which is working together with B4x). I searched for a standalone creator which is easy to handle. I came to this site: QR-code generator. I uses Javascript to generate the QR-code. I''ve modified the example (removed all inputfields and replaced them with simple variables).

Resize Bitmap with a maximum Byte limit

Sometimes the images we use in our Apps are overly large. In some cases, images are entered by the user and therefore we do not know the size. And to manage them we need them to fall within a certain Byte limit. How to reduce them within the limit? Here is a code that allows you to redimension the images while maintaining the proportion and returning within the Byte mitie that serves us
