- The bitmap image for recognition.public void setBarCodeImage(java.lang.String filename)
Sets image file for recognition. Must be called before ReadBarCodes() method.

filename
- The image file for recogniton.public void setBarCodeReadType(SingleDecodeType... barcodeTypes)
Sets SingleDecodeType
type array for recognition.
Must be called before ReadBarCodes() method.
