推荐答案

你有使用ImageMagick的？您可以使用GDI +，如果你的目的是要在其他尺寸重新发货的图像。 <一href=\"http://www.switchonthe$c$c.com/tutorials/csharp-tutorial-image-editing-saving-cropping-and-resizing\" rel=\"nofollow\">http://www.switchonthe$c$c.com/tutorials/csharp-tutorial-image-editing-saving-cropping-and-resizing使此功能调整。我用这个教程在过去的水印：的http：// WWW。codeproject.com / KB / GDI加/ watermark.aspx

Do you have to use ImageMagick? You can use GDI+ if your aim is to redeliver an image in another size. http://www.switchonthecode.com/tutorials/csharp-tutorial-image-editing-saving-cropping-and-resizing gives this function for resizing. I've used this tutorial in the past for watermarking: http://www.codeproject.com/KB/GDI-plus/watermark.aspx

private  static Image resizeImage(Image imgToResize, Size size)
{
  int sourceWidth = imgToResize.Width;
  int sourceHeight = imgToResize.Height;

  float nPercent = 0;
  float nPercentW = 0;
  float nPercentH = 0;

  nPercentW = ((float)size.Width / (float)sourceWidth);
  nPercentH = ((float)size.Height / (float)sourceHeight);

  if (nPercentH < nPercentW)
    nPercent = nPercentH;
  else
    nPercent = nPercentW;

  int destWidth = (int)(sourceWidth * nPercent);
  int destHeight = (int)(sourceHeight * nPercent);

  Bitmap b = new Bitmap(destWidth, destHeight);
  Graphics g = Graphics.FromImage((Image)b);
  g.InterpolationMode = InterpolationMode.HighQualityBicubic;

  g.DrawImage(imgToResize, 0, 0, destWidth, destHeight);
  g.Dispose();

  return (Image)b;
}
