Demonstrates the capabilities operation, which describes what the installed version of Chilkat can do: the range of QR versions, the error-correction levels, the operations, the image formats and the limits. A program can check for a feature here instead of testing for a Chilkat version number. The request can be an empty JSON object. PowerShell
