Question

嘿所有我有以下命令行，它非常适合我想要做的但无法将其转换为C＃Magick.net版本：

convert YnTf9.png ^
( -clone 0 -blur 0x5 -gravity center -crop 400x300+0+0 +repage ) ^
( -clone 0 -resize x300 ) ^
-delete 0 ^
-gravity center -compose over -composite ^
result.png

到目前为止，我有这个c＃代码：

using (MagickImage image = new MagickImage(@"C:\Users\David\Pictures\YnTf9.png"))
{
     using (MagickImage backgroundImg = (MagickImage)image.Clone())
     {
          backgroundImg.Blur(0, 5);
          backgroundImg.Crop(400, 300, Gravity.Center);
          backgroundImg.RePage();
          backgroundImg.Resize(0, 300);

          image.Composite(backgroundImg, Gravity.Center, CompositeOperator.SrcOver);
          image.Write("CODETest.png");
     }
}

刚刚做完之后，我就把它运行了，它就像普通的图像一样出现了：

什么时候看起来像这样：

所以我知道我没有用以太正确的顺序和/或正确的命令。

如果有人能为我翻译它会很棒！：）

Answer 1

括号之间的-clone会创建一个单独的图像：

convert YnTf9.png ^
# Creates a copy of YnTf9.png.
( -clone 0 -blur 0x5 -gravity center -crop 400x300+0+0 +repage ) ^
# Creates another copy of YnTf9.png
( -clone 0 -resize x300 ) ^
# Removes YnTf9.png from the image list, you now only have the two clones
-delete 0 ^
-gravity center -compose over -composite ^
result.png

但在您的情况下，您不需要创建第二个克隆。您的命令可以转换为：

using (MagickImage image = new MagickImage("i:/YnTf9.png"))
{
    using (IMagickImage backgroundImg = image.Clone())
    {
        backgroundImg.Blur(0, 5);
        backgroundImg.Crop(400, 300, Gravity.Center);
        backgroundImg.RePage();

        // Resize the original image instead of creating a clone, resizing it and then
        // delete the original.
        image.Resize(0, 300);

        backgroundImg.Composite(image, Gravity.Center, CompositeOperator.SrcOver);
        backgroundImg.Write("i:/result.png");
    }
 }

搞定了

using (MagickImage image = new MagickImage(bitmap))
    {
        using (IMagickImage backgroundImg = image.Clone())
        {
            backgroundImg.Blur(0, 5);
            backgroundImg.Crop(400, 300, Gravity.Center);
            backgroundImg.RePage();

            image.Resize(0, 300);

            IMagickImage _shadow = new MagickImage(MagickColor.FromRgb(0, 0, 0), image.Width + 20, 400);
_shadow.Shadow(backgroundImg.Width, 400, 10, (Percentage)90);

            backgroundImg.Composite(_shadow, Gravity.Center, CompositeOperator.Atop);
            backgroundImg.Composite(image, Gravity.Center, CompositeOperator.SrcAtop);
            backgroundImg.Write(@"C:\Users\David\Pictures\NEWest.png");
        }
    }

ImageMagick命令行到Magick.net C＃
