EasilyNET.Images 1.5.5

EasilyNET.Images

包含 QRCode 工具,由于绘图等一些操作需要平台依赖包支持,所以会较大,因此单独打包. 简化二维码生成,一般仅需使用 Encode 就够了.

使用 QRCode 功能

• 使用 Nuget GUI 工具添加至项目
• Install-Package EasilyNET.Images
• 若包含中文推荐安装 System.Text.Encoding.CodePages
• 并在程序入口处添加注册代码. Programe.cs

var builder = WebApplication.CreateBuilder(args);

System.Text.Encoding.RegisterProvider(System.Text.CodePagesEncodingProvider.Instance);

QRCode 生成以及解析

• 1.生成二维码.

/// <summary>

/// </summary>
/// <param name="text">文本内容</param>
/// <param name="keepWhiteBorderPixelVal">白边处理(负值表示不做处理，最大值不超过真实二维码区域的1/10)</param>
/// <param name="width">二维码边长</param>

QrCode.Encode(string text, int keepWhiteBorderPixelVal = -1, int width = 320, string background = "FFF", string foreground = "000")

/// <returns></returns>
QrCode.Decode(Stream stream)

QrCode.Decode<T>(Stream stream)

/// <summary>
/// 从byte数组中解析二维码
