Class Barcode

java.lang.Object
com.codename1.ai.vision.Barcode
public final class Barcode extends Object
Portable barcode observation with normalized geometry. Format names are backend-neutral constants such as QR_CODE, DATA_MATRIX, CODE_128, and EAN_13; unknown symbologies use UNKNOWN. Corner points are ordered around the code when supplied by the backend and may be empty when geometry is unavailable.

      public Barcode(String value, String format, byte[] rawBytes, VisionRect bounds, VisionPoint[] corners)
      Creates a barcode without backend metadata.
      Parameters:
      value - decoded display value, or null
      format - normalized symbology name
      rawBytes - original payload bytes when available
      bounds - normalized top-left-origin bounds
      corners - normalized corner points

      public Barcode(String value, String format, byte[] rawBytes, VisionRect bounds, VisionPoint[] corners, VisionMetadata metadata)
      Creates a complete barcode observation.
      Parameters:
      value - decoded display value, or null
      format - normalized symbology name
      rawBytes - original payload bytes when available
      bounds - normalized top-left-origin bounds
      corners - normalized corner points
      metadata - backend identity and optional diagnostic values
