Class Barcode

Namespace

TwBlazor.Services.Encoding

Assembly

TwBlazor.dll

An encoded one-dimensional barcode: a row of dark and light modules (the narrowest bar width), ready to be drawn by any renderer.

public sealed class Barcode : IEncodedSymbol

Inheritance

object

Implements

IEncodedSymbol

Extension Methods

SymbolSvg.GetSvgPath(IEncodedSymbol, int?, int)

SymbolSvg.GetSvgViewBox(IEncodedSymbol, int?, int)

SymbolSvg.ToSvg(IEncodedSymbol, SymbolSvgOptions?)

SymbolSvg.ToSvgDataUri(IEncodedSymbol, SymbolSvgOptions?)

Remarks

The barcode is immutable, so it can be cached and shared freely. It does not include the quiet zone; a renderer adds that margin itself, using QuietZone as the recommended width. Draw it with the SymbolSvg methods.
