C# 中的 GIMP 筛选器

Question

我整天都在努力运行这段代码，但没有机会。我想在图像上执行 GIMP 过滤器，稍后将其保存到某个路径。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，但每次出现错误时都出现无法读取字符串的错误。这是 .scm：

如果有人能帮忙，我会很开心，因为我绝望了。谢谢！

Answer 1

也许去这里看看并尝试一下这种方法

但从事情的外观来看，你：

 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)""";

或者本质上：

    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)""";

从您提供的错误所说的内容来看，您的代码中的上述字符串存在问题。试试这几个人，然后给我评论。

我自己想通了 - 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，效果很好。
