PSStringToQRCode

PowerShell-module for converting text strings to QR-code and display it on screen, or save it as a .PNG-image.

All the heavy lifting is done these Git-hub projects:

• Net.Codecrete.QrCodeGenerator by Manuel Bl. (https://github.com/manuelbl/QrCodeGenerator)
• SkiaSharp by Mono Project (https://github.com/mono/SkiaSharp)
• Svg.Skia by Wiesław Šoltés (https://github.com/wieslawsoltes/Svg.Skia)

All credits to the respectfull creators of the assemly-code used. I simply pieced it together, so that it will perform a very specific task in PowerShell :)
