Reading a bar code in an image

In WEBDEV sites, it is also possible to read the characteristics of a bar code in an image.
To read a bar code found in an image:
  1. Select the image that contains the bar code to decode. This image can be:
    • an image in an Image control.
    • an image file.
    • an image in memory.
  2. Declare a BarCode variable if necessary. The characteristics of the bar code will be saved in this variable.
  3. Use BCDecode to decode the bar code.
Example: Reading a bar code in an Image control:
// Decode a QR Code found in an Image control
bc is BarCode
bc = BCDecode(IMG_BarCode)
IF ErrorOccurred = False _AND_ bc.TypeBarCode = BC_QRCODE ...
_AND_ bc.TypeContent =  bcTypeEmail THEN
Info("Email address: " + bc.Content)
END
