java.lang.Object

com.google.zxing.qrcode.detector.FinderPatternFinder

com.google.zxing.multi.qrcode.detector.MultiFinderPatternFinder

public final class MultiFinderPatternFinder
extends FinderPatternFinder

This class attempts to find finder patterns in a QR Code. Finder patterns are the square markers at three corners of a QR Code.

This class is thread-safe but not reentrant. Each thread must allocate its own object.

In contrast to FinderPatternFinder, this class will return an array of all possible QR code locations in the image.

Use the TRY_HARDER hint to ask for a more thorough detection.
