BarcodeImageParams class

Optional barcode image parameters.

Constructors

BarcodeImageParams([BarcodeImageFormat? imageFormat, CodeLocation? textLocation, String? foregroundColor, String? backgroundColor, GraphicsUnit? units, double? resolution, double? imageHeight, double? imageWidth, int? rotationAngle])

Constructor

BarcodeImageParams.fromJson(Map<String, dynamic> json)

Creates a BarcodeImageParams instance from a JSON representation.

Properties

backgroundColor ↔ String?

Background color of the barcode image. Value: Color name from https://reference.aspose.com/drawing/net/system.drawing/color/ or ARGB value starting with #. For example: AliceBlue or #FF000000. Default value: White.

getter/setter pair

foregroundColor ↔ String?

Specify the display color for bars and content. Value: Color name from https://reference.aspose.com/drawing/net/system.drawing/color/ or ARGB value starting with #. For example: AliceBlue or #FF000000. Default value: Black.

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

imageFormat ↔ BarcodeImageFormat?

Barcode output image format. Default value: png.

getter/setter pair

imageHeight ↔ double?

Height of the barcode image in the specified units. Default units: pixels. Decimal separator is a dot.

getter/setter pair

imageWidth ↔ double?

Width of the barcode image in the specified units. Default units: pixels. Decimal separator is a dot.

getter/setter pair

resolution ↔ double?

Resolution of the barcode image. One value for both dimensions. Default value: 96 dpi. Decimal separator is a dot.

getter/setter pair

rotationAngle ↔ int?

Barcode image rotation angle, measured in degrees. For example, RotationAngle = 0 or RotationAngle = 360 means no rotation. If RotationAngle is not equal to 90, 180, 270, or 0, it may increase the difficulty for the scanner to read the image. Default value: 0.

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

textLocation ↔ CodeLocation?

Specify the displayed text location. Set to CodeLocation.None to hide CodeText. Default value depends on BarcodeType: CodeLocation.Below for 1D barcodes and CodeLocation.None for 2D barcodes.

getter/setter pair

units ↔ GraphicsUnit?

Common units for all measurements. Default units: pixels.

getter/setter pair
