Class GenericMultipleBarcodeReader
java.lang.Object
com.google.zxing.multi.GenericMultipleBarcodeReader
- All Implemented Interfaces:
- MultipleBarcodeReader
public final class GenericMultipleBarcodeReader
- extends java.lang.Object
- implements MultipleBarcodeReader
Attempts to locate multiple barcodes in an image by repeatedly decoding portion of the image.
After one barcode is found, the areas left, above, right and below the barcode's
ResultPoint
s are scanned, recursively.
A caller may want to also employ ByQuadrantReader
when attempting to find multiple
2D barcodes, like QR Codes, in an image, where the presence of multiple barcodes might prevent
detecting any one of them.
That is, instead of passing a Reader
a caller might pass
new ByQuadrantReader(reader)
.
