- Handling errors
- Decoding QRCode
BCDecode (Function) In french: CBDécode Decodes the information contained in a bar code. This bar code is contained in an image (image displayed in an Image control, file of an image or image in memory). The type of bar code to be decoded depends on the execution platform:  Only QR Codes can be decoded.
Attention The strikethrough code must cover a sufficiently large area of the source image, with sufficient contrast and sharpness for decoding.
Syntax
<Result> = BCDecode(<Image>)
<Result>: BarCode variable BarCode variable initialized with the information read in the bar code. <Image>: Character string Image of bar code to decode. This parameter can correspond to: Remarks Handling errors To find out whether the retrieval failed, use: - the ErrorOccurred variable,
- the TypeBarCode property of the BarCode variable. If this property differs from BC_QRCODE, the bar code was not detected or decoded.
