BlazorBarcodes 1.0.2

BlazorBarcodes

Provides blazor component for rendering 1D & 2D codes.

This is a really simple wrapper around huysentruitw´s Barcoder and as such supports the same barcode types, which at this time are:

• 2 of 5
• Aztec Code
• Codabar
• Code 39
• Code 93
• Code 128
• Code 128 GS1
• Data Matrix (ECC 200)
• Data Matrix GS1
• EAN 8
• EAN 13
• KIX (used by PostNL)
• PDF 417
• QR Code
• RM4SC (Royal Mail 4 State Code)
• UPC A
• UPC E

Targets

.Net 5

Install

PM> Install-Package BlazorBarcodes

Usage

Add the following using statements.

@using BlazorBarcodes
@using BlazorBarcodes.Barcodes
@using BlazorBarcodes.Encoders

Pass a string content and either a BarcodeType(enum), Encoder or encoding function to the component.

<BarcodeComponent Style="width:200px;height:200px"
                    BarcodeType="@BarcodeTypes.DataMatrix"
                    Content="Hello World!">
</BarcodeComponent>

The codes are renderer as SVG by default.

If you´d like to quickly play around with the different barcodes, you create an easy selection like this.

<div style="display:flex; flex-direction:column">

    <input type="text" @bind="Content">

    <select @bind="Type">
        @foreach (var barcode in BarcoderWrapper.Barcodes.Barcode.All)
        {
            <option value="@barcode.Type" disabled="@(!barcode.Encoder.CanEncode(Content, out string error))">
                @(string.Format("{0}{1}", barcode.Name, error is not null ? $": {error}" : ""))
            </option>
        }
    </select>

    <BarcodeComponent Style="width:200px;height:200px"
                      BarcodeType="@Type"
                      Content="@Content">
    </BarcodeComponent>
</div>

@code {
    public BarcodeTypes Type { get; set; }

    public string Content { get; set; } = "";
}

Options

Passed to the Barcoder renderer

bool IncludeEANContentAsText

Shows exception message instead of the rendered code, in case the content is not compatible with the encoder

bool ShowExceptionMessages

Encoders

The encoding functions in Barcoder have been wrapped in classes implementing my own IEncoder interface, since I wanted to be able to pass encoders around and also saw it as an opportunity to play around with C# source code generators.

You can still use pass the pre-existing encode methods to the component though.
