C# 中的 GIMP 过滤器

Question

我整天都在尝试获取此代码运行，但没有机会。我想对图像执行 GIMP 过滤器，然后将其保存到特定路径。使用此代码：

string choosenFile = "D:\here\is\the\image";
string gimpFile = "D:\here\is\my\gimp exe";



void seamlessFilter() {
    try {
        if (!string.IsNullOrEmpty(choosenFile)) {
            string a = @"-b ""(script-fu-tile \""" 
            + choosenFile
            + "100 100 0 TRUE 70"  
            + @")"" -b ""(gimp-quit 0)""";
            string result = ExecuteCommandSync(a);
            Texture2D newTex = loadImage (new Vector2(200, 200), Path.GetFullPath(choosenFile));
            newTex = null;
        } else {
            UnityEngine.Debug.Log("Please select a image");
        }
    } catch (Exception ex){
        UnityEngine.Debug.Log (ex.ToString ());
    }
}

public string ExecuteCommandSync(string command) {
    ProcessStartInfo processStartInfo = new ProcessStartInfo (gimpFile, command);
    processStartInfo.RedirectStandardOutput = true;
    processStartInfo.UseShellExecute = false;
    processStartInfo.CreateNoWindow = true;

    Process process = new Process ();
    process.StartInfo = processStartInfo;

    process.Start ();
    StreamReader reader = process.StandardOutput;
    string result = reader.ReadToEnd ();
    Console.WriteLine (result);
    return result;
}

我尝试执行过滤器，但每次都出现错误，无法读取字符串。这是.scm:

如果有人能提供帮助，我会很高兴，因为我很绝望。谢谢！

Answer 1

也许去看看here试试这个方法

但是从外观上看你的：

 string a = @"-b ""(script-fu-tile \""" 
        + choosenFile
        + "100 100 0 TRUE 70"  
        + @")"" -b ""(gimp-quit 0)""";

应该看起来更像这样：

string a = @"gimp-2.6.exe -i -b ""(script-fu-tile \""" +
               choosenFile + @"\""0 100 100 0 TRUE 70)"" -b ""(gimp-quit 0)""";

或本质上：

    string draw = "0";
    string blendx = "100";
    string blendy = "100";
    string overlap = "0";
    string sqrText = "TRUE";
    string adjBright = "70";
    string a = @"gimp-2.6.exe -i -b ""(simple-unsharp-mask \""" +
              path + @"\"" " + draw + " " + blendx + " " + blendy + " " + overlap + " "+ sqrText + " " + adjBright +
              @")"" -b ""(gimp-quit 0)""";

从错误信息来看，您提供的代码中的上述字符串存在问题。试试那几个，然后给我评论。

Answer 2

我自己弄明白了 - 问题是，第一个参数 img 需要一个对象，但我写了一个字符串作为第一个参数。所以我编辑了我的 scm 脚本以将对象包装为字符串并且效果很好。
