图像操作库 Magick.NET

ImageMagick 是一个很强大的图像操作库，支持超过 100 种的文件格式。而 Magick.NET 可以让你在 .NET 环境中使用 ImageMagick ，而无需在系统中单独安装 ImageMagick。

示例代码：

// Read first frame of gif image
using (MagickImage image = new MagickImage("Snakeware.gif"))
{
  // Save frame as jpg
  image.Write("Snakeware.jpg");
}
 
// Write to stream
MagickReadSettings settings = new MagickReadSettings();
// Tells the xc: reader the image to create should be 800x600
settings.Width = 800;
settings.Height = 600;
 
using (MemoryStream memStream = new MemoryStream())
{
  // Create image that is completely purple and 800x600
  using (MagickImage image = new MagickImage("xc:purple", settings))
  {
    // Sets the output format to png
    image.Format = MagickFormat.Png;
    // Write the image to the memorystream
    image.Write(memStream);
  }
}
 
// Read image from file
using (MagickImage image = new MagickImage("Snakeware.png"))
{
  // Sets the output format to jpeg
  image.Format = MagickFormat.Jpeg;
  // Create byte array that contains a jpeg file
  byte[] data = image.ToByteArray();
}
