Barcode
Defined in library scandit_datacapture_barcode
- Barcode
class BarcodeAdded in version 6.7.0
A recognized barcode.
- data
String? get data
Added in version 6.7.0
The data of this code as a unicode string.
For some types of barcodes/2d codes (for example Data Matrix, Aztec, Pdf417), the data may contain non-printable characters, characters that cannot be represented as unicode code points, or nul-bytes in the middle of the string. data may be null for such codes. How invalid code points are handled is platform-specific and should not be relied upon. If your applications relies on scanning of such codes, use rawData instead which is capable of representing this data without loss of information.
- rawData
String get rawData
Added in version 6.7.0
The raw data contained in the barcode.
Use this property instead of data if you are relying on binary-encoded data that cannot be represented as unicode strings.
Unlike data which returns the data in Unicode representation, the rawData returns the data with the encoding that was used in the barcode. See encodingRanges for more information.
The raw data is base64 encoded as a string and might need to be decoded to be used.
- addOnData
String? get addOnData
Added in version 6.7.0
If present, this property returns the add-on code (also known as extension code) associated with this barcode. See Scan Add-On/Extension Codes to understand how add-ons can be enabled.
- compositeRawData
String? get compositeRawData
Added in version 6.7.0
The raw data is base64 encoded as a string and might need to be decoded to be used.
- encodingRanges
List<EncodingRange> get encodingRanges
Added in version 6.7.0
Array of encoding ranges. Each entry of the returned encoding array points into bytes of rawData and indicates what encoding is used for these bytes. This information can then be used to convert the bytes to unicode, or other representations. For most codes, a single encoding range covers the whole data, but certain 2d symbologies, such as Symbology.qr allow to switch the encoding in the middle of the code.
The returned encoding ranges are sorted from lowest to highest index. Each byte in rawData is contained in exactly one range, e.g. there are no holes or overlapping ranges.
- location
Quadrilateral get location
Added in version 6.7.0
The location of the code. The coordinates are in image-space, meaning that the coordinates correspond to actual pixels in the image. For display, the coordinates need first to be converted into screen-space using the data capture view.
The meaning of the values of Quadrilateral.topLeft etc is such that the top left point corresponds to the top left corner of the barcode, independent of how the code is oriented in the image.
Note
If you use BarcodeTracking you should not use this location at all. Instead use the always up-to-date TrackedBarcode.location.
Warning
In case the feature is not licensed, a quadrilateral with all corners set to 0, 0 is returned.
- isGS1DataCarrier
bool get isGS1DataCarrier
Added in version 6.7.0
True for codes that carry GS1 data.
- compositeFlag
CompositeFlag get compositeFlag
Added in version 6.7.0
Flag to hint whether the barcode is part of a composite code.
- isColorInverted
bool get isColorInverted
Added in version 6.7.0
Whether the recognized code is color inverted (printed bright on dark background).
