TTMSFNCWXCustomQRDecoder Class

Base class that decodes QR codes from images using an embedded web control. Provides the decoding methods, library location selection, and result dispatching that the published decoder component exposes.

API unit family: TMSFNCWXQRDecoder Inherits from: TTMSFNCWXCustomBarcodeDecoderBase

Syntax

TTMSFNCWXCustomQRDecoder = class(TTMSFNCWXCustomBarcodeDecoderBase)

Remarks

Decoding runs asynchronously inside the hosted web view; results are delivered through the supplied callback or the decoded event rather than being returned synchronously.

Methods

Name	Description
DecodeFromBase64	Decodes a QR code from a base64-encoded image and reports the result through the supplied callback.
DecodeFromBase64WithFilename	Decodes a QR code from a base64-encoded image while associating the result with a file name, so callers can correlate the outcome with the source image.
