Q: Is this agent skill safe to install?

Review the displayed partner audits, complete source, permissions, dependencies, and exact revision before installing.

Implement Syncfusion ASP.NET Core Barcode components including BarcodeGenerator (1D codes like Code39, Code128, Codabar), QR Code Generator, and DataMatrix Generator. Use this when rendering barcodes, implementing QR codes with logo embedding, or generating DataMatrix codes. This skill covers barcode type selection, color and dimension customization, display text configuration, and export functionality (JPG, PNG, Base64).

⚠️ STRICT USAGE RULES — MANDATORY FOR ALL CODE GENERATION

These rules are non-negotiable. They must be followed for every code generation request using this skill.

Rule A — Use Only Provided Reference Files

You must always read references/getting-started.md for every request
Read other reference files only if they directly match the user's query:
- barcode-types.md → 1D linear barcodes (Code39, Code128, Codabar, etc.)
- qr-code.md → QR codes with optional logo embedding
- data-matrix.md → DataMatrix barcodes
- customization.md → color, size, display text properties
- export.md → PNG/JPG/Base64 export functionality
No external knowledge is allowed:
- ❌ Do NOT use internet documentation
- ❌ Do NOT use training-data assumptions
- ✅ If a feature cannot be confirmed from reference files, apply Rule B

Rule B — No Guessing, No Inference

If a feature, property, API, or behavior is not explicitly documented in the reference files:

You must NOT:

Invent properties or methods
Infer missing APIs or parameters
Assume deprecated or undocumented features exist
Generalize from other Syncfusion components

Instead, respond with:

⚠️ NOT DOCUMENTED: [feature name] is not covered in the reference files.
Skipping this feature to avoid generating incorrect code.

Barcode Components Overview

Syncfusion EJ2 ASP.NET Core provides three barcode components via tag helpers:

Component	Tag Helper	Best For	Key Properties
BarcodeGenerator	`<ejs-barcodegenerator>`	Linear 1D barcodes (Code39, Code128, Codabar, etc.)	`type`, `value`, `foreColor`, `width`, `height`
QR Code Generator	`<ejs-qrcodegenerator>`	2D QR codes, URLs, large payloads	`value`, `width`, `height`, `foreColor`, `logoUrl`
DataMatrix Generator	`<ejs-datamatrixgenerator>`	2D labels, print media, compact storage	`value`, `width`, `height`, `foreColor`

All three support:

✅ Custom colors (foreColor)
✅ Dimension control (width, height)
✅ Display text customization
✅ Export to PNG/JPG/Base64

Navigation Guide

Always read references/getting-started.md first, then read only files relevant to the request.

Reference File	Read When the Query Involves
📄 getting-started.md	Every request — NuGet setup, tag helper registration, CDN, script manager
📄 barcode-types.md	1D barcodes, Code39, Code128, Codabar, Code11, Code32, Code93, barcode selection guidance
📄 qr-code.md	QR code rendering, logo embedding, error correction, versioning (v1–v40)
📄 data-matrix.md	DataMatrix overview, rendering, use cases
📄 customization.md	Color (`foreColor`), dimensions (`width`/`height`), display text, rendering mode
📄 export.md	Image export (PNG/JPG), Base64 export, export methods

Quick Start

1. Install NuGet Package

Install-Package Syncfusion.EJ2.AspNet.Core

2. Register Tag Helper (`~/Pages/_ViewImports.cshtml`)

@addTagHelper *, Syncfusion.EJ2

3. Add CDN Resources (`~/Pages/Shared/_Layout.cshtml`)

<head>
    <link rel="stylesheet" href="https://cdn.syncfusion.com/ej2/{{ site.ej2version }}/fluent.css" />
    <script src="https://cdn.syncfusion.com/ej2/{{ site.ej2version }}/dist/ej2.min.js"></script>
</head>
<body>
    ...
    <ejs-scripts></ejs-scripts>
</body>

4. Basic Examples

BarcodeGenerator (Code128)

<ejs-barcodegenerator id="barcode"
    width="200px"
    height="150px"
    type="Code128"
    value="SYNCFUSION"
    mode="SVG">
</ejs-barcodegenerator>

QR Code

<ejs-qrcodegenerator id="qrcode"
    width="200px"
    height="200px"
    value="https://syncfusion.com"
    mode="SVG">
</ejs-qrcodegenerator>

DataMatrix

<ejs-datamatrixgenerator id="datamatrix"
    width="200px"
    height="150px"
    value="Syncfusion"
    mode="SVG">
</ejs-datamatrixgenerator>

Common Patterns

Choose Barcode Type by Content

Use Case	Recommended Type	Reason
Numeric only, short data	Codabar or Code11	Compact, simple
Alphanumeric, uppercase	Code39	Industry standard for labels
Full ASCII, variable length	Code128	Most versatile, widely supported
Pharmaceutical (Italian)	Code32	Specialized regulatory requirement
Dense alphanumeric data	Code93	Better compression than Code39
URL or large payload	QR Code	Handles complex data, scannable by phones
Label/print media with compact storage	DataMatrix	Industry standard for logistics

Customize Colors (All Generators)

<ejs-barcodegenerator id="barcode"
    width="200px" height="150px"
    type="Code128" value="SYNCFUSION"
    foreColor="red" mode="SVG">
</ejs-barcodegenerator>

Embed Logo in QR Code

<ejs-qrcodegenerator id="qrcode"
    width="200px" height="200px"
    value="https://syncfusion.com"
    logoUrl="logo.png"
    mode="SVG">
</ejs-qrcodegenerator>

Export Barcode on Button Click

<button onclick="exportBarcode()">Export as JPG</button>

<script>
  function exportBarcode() {
    var barcode = document.getElementById("barcode").ej2_instances[0];
    barcode.exportImage('MyBarcode', 'JPG');
  }
  
  function exportAsBase64() {
    var barcode = document.getElementById("barcode").ej2_instances[0];
    var base64String = barcode.exportAsBase64Image('PNG');
    console.log(base64String);
  }
</script>

Hide Display Text

<ejs-barcodegenerator id="barcode"
    width="200px" height="150px"
    type="Code128" value="SYNCFUSION"
    displayText.visibility="false"
    mode="SVG">
</ejs-barcodegenerator>

When to Use This Skill

✅ Rendering any barcode type in ASP.NET Core
✅ Choosing between BarcodeGenerator, QR Code, and DataMatrix
✅ Customizing barcode appearance (color, size, text)
✅ Embedding a logo in a QR code
✅ Exporting barcodes as images or Base64 strings
✅ Selecting appropriate barcode type for use case
