Parameters

fileFullPath: A string defining the file path.
templateName: The template name.

Return Value

All barcode text results decoded successfully.

Exceptions

BarcodeReaderException

Code Snippet

BarcodeReader reader = new BarcodeReader();
/*Init DBR license before decoding*/
TextResult[] result = reader.decodeFile("your file path", "");
reader.destroy();

decodeFileInMemory

TextResult[] result = reader.decodeFileInMemory(fis, "");
reader.destroy();

decodeBuffer

Decode barcodes from the memory buffer containing image pixels in defined format.

TextResult[] decodeBuffer(byte[] buffer, int width, int height, int stride, int enumImagePixelFormat, String templateName) throws BarcodeReaderException

Parameters

buffer: The array of bytes which contain the image data.
Width: The width of the image in pixels.
