A callback method that is used to process deblurred images generated by BarCodeReadPreprocessCommand object.
public delegate bool BarCodeReadPreprocessCallback(
RasterImage binarizedImage,
LeadRect barcodeZone
)
Public Delegate Function BarCodeReadPreprocessCallback( _
ByVal binarizedImage As RasterImage, _
ByVal barcodeZone As LeadRect _
) As Boolean
typedef BOOL (^LTBarCodeReadPreprocessCallback)(LTRasterImage * __null_unspecified binarizedImage, LeadRect barcodeZone)
- (BOOL)run:(LTRasterImage *)image
progress:(nullable LTRasterCommandProgress)progressHandler
preprocess:(nullable LTBarCodeReadPreprocessCallback)preprocessCallback
error:(NSError **)error
public void removePreprocessListener()
public void setPreprocessListener(BarCodeReadPreprocessListener value)
public delegate bool BarCodeReadPreprocessCallback(
RasterImage^ binarizedImage,
LeadRect barcodeZone
)
binarizedImage
A RasterImage that represents the Barcode Read Preprocessed (Binarized) image.
barcodeZone
A LeadRect that represents the zone in the image where barcode data has been found.
true to continue, false to abort.
Barcode analyzer engine generates eight deblurring possibilities of the processed image. If barcode reader does not find barcode data, this callback should return a false value in order to get the next deblurred image, otherwise true value should be returned.
