我正在寻找将近一个小时的示例，以在C#中使用imagemagick.net，但我找不到任何东西。

我所需要的只是将图像(.jpg)调整为新的尺寸图像(jpg，也是如此)，如果您知道如何添加水印，那就太好了。

我从下载了imagemagick.net

最佳答案

您必须使用ImageMagick吗？如果您要重新传送其他尺寸的图像，则可以使用GDI +。 http://www.switchonthecode.com/tutorials/csharp-tutorial-image-editing-saving-cropping-and-resizing提供此功能来调整大小。我过去曾将本教程用于加水印: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;
}
