三.使用说明

本库基于 SkiaSharp 与 ZXing.Net 提供标签设计与渲染功能，支持文本、二维码、条形码等元素的标签模板设计与图像生成。

3.1 主要类与接口

| 名称 | 类型 | 描述 | | ---------------------- | ------ | -------------------------------------------------------------------------------- | | Label | 类 | 标签对象，包含标签尺寸与元素集合。 | | LabelElement | 抽象类 | 标签元素基类，包含 ID、名称、坐标(Location)、尺寸(Size)。 | | LabelText | 类 | 标签文本元素，包含文本内容、字体、对齐方式等。 | | LabelQrCode | 类 | 标签二维码元素，包含内容值、尺寸等。 | | LabelBarcode | 类 | 标签条形码元素，包含内容值、条码格式。 | | LabelRenderer | 类 | 标签渲染器，将 Label 对象渲染为图片字节数组。 | | ILabelRenderer | 接口 | 标签渲染器接口，定义 GenerateImage / GenerateImage64 方法。 | | ILabelElement | 接口 | 标签元素接口。 | | BarcodeFormatType | 枚举 | 条码格式类型。 |

3.2 使用方法

  1. 创建标签并添加文本元素
using JCoder.Label4Net;
using System.Drawing;

// 创建标签，宽 400 x 高 300 像素
var _label = new Label
{
    Size = new Size(400, 300),
    ImageSize = new Size(800, 600),  // 输出图像放大2倍
};

// 添加文本元素
var _text = new LabelText
{
    Location = new Point(20, 20),
    Size = new Size(360, 40),
    Content = "Hello, Label!",
    FontSize = 18,
};
_label.Elements.Add(_text);
  1. 添加二维码元素
using JCoder.Label4Net;
using System.Drawing;

var _label = new Label { Size = new Size(400, 300) };

// 添加二维码元素
var _qr = new LabelQrCode
{
    Location = new Point(140, 80),
    Size = new Size(120, 120),
    Content = "https://www.example.com",
};
_label.Elements.Add(_qr);
  1. 添加条形码元素
using JCoder.Label4Net;
using System.Drawing;

var _label = new Label { Size = new Size(400, 200) };

// 添加条形码元素
var _barcode = new LabelBarcode
{
    Location = new Point(20, 60),
    Size = new Size(360, 80),
    Content = "123456789012",
    Format = BarcodeFormatType.CODE_128,
};
_label.Elements.Add(_barcode);
  1. 渲染标签为图片
using JCoder.Label4Net;

var _label = new Label { Size = new Size(400, 300) };
// ... 添加元素 ...

var _renderer = new LabelRenderer();

// 生成图片字节数组 (JPEG)
byte[] _imageBytes = _renderer.GenerateImage(_label);
File.WriteAllBytes(@"C:\Output\label.jpg", _imageBytes);

// 生成 Base64 字符串
string _base64 = _renderer.GenerateImage64(_label);
  1. 使用数据字典动态渲染
using JCoder.Label4Net;

var _label = new Label { Size = new Size(400, 300) };
// ... 添加包含占位符的元素 ...

// 传入数据字典替换标签中的变量
var _data = new Dictionary<string, string>
{
    ["Name"] = "Jack",
    ["OrderNo"] = "SO20260924001",
};

var _renderer = new LabelRenderer();
byte[] _image = _renderer.GenerateImage(_label, _data);
