AutoIt Requires Chilkat v11.7.0+

Validate a QR Code Request

See more QR Code Examples

Demonstrates the validate operation, which examines a request without producing anything. The scope says how far to look: definition checks the options, capacity also checks that the data fits a QR symbol, and layout also checks the rendered size against the limits. The response has a validationStatus of valid or invalid, a list of checks, and findings[] describing what is wrong. A request that cannot be understood at all, such as one with a misspelled option, still makes the call fail in the usual way. AutoIt
