Aspose::BarCode::BarCodeRecognition::BarCodeReader::SetBarCodeImage method

BarCodeReader::SetBarCodeImage(System::SharedPtr<System::Drawing::Bitmap>) method

Sets bitmap image for recognition. Must be called before ReadBarCodes() method.

void Aspose::BarCode::BarCodeRecognition::BarCodeReader::SetBarCodeImage(System::SharedPtr<System::Drawing::Bitmap> value)

Parameter	Type	Description
value	System::SharedPtr<System::Drawing::Bitmap>	The bitmap image for recognition.

Remarks

This sample shows how to detect Code39 and Code128 barcodes.
