NGUI图集切割代码

原地址：http://blog.csdn.net/u011440375/article/details/9707491

因为最近工作用NGUI比较多，修改图集时还没原图，有时候需要把图集重新切割开来，用代码会比较方便，一下贴出主要代码

首先读取NGUI图集的信息

[csharp] view plaincopy
UIAtlas mAtlas  ;
         GameObject[] SelectedAsset=Selection.gameObjects;
         if (SelectedAsset.Length == )
         {
             mAtlas = SelectedAsset[].GetComponent<UIAtlas>();  

             if (mAtlas != null)
             {
                 string atlasFile = string.Format("{0}.txt", mAtlas.name);
                 string atlasPng = string.Format("{0}.png", mAtlas.name);
                 char[] ch = { '.' };
                 string path = AssetDatabase.GetAssetPath(SelectedAsset[]);
                 FileInfo aFileinfo = new FileInfo(path);
                 string th = aFileinfo.DirectoryName;
                 string[] strs = path.Split(ch);  

                 if (File.Exists(atlasFile))
                 {
                     File.Delete(atlasFile);
                 }
                 StreamWriter sw = new StreamWriter(strs[] + ".txt");
                 StringBuilder sb = new StringBuilder();
                 foreach (UIAtlas.Sprite sprite in mAtlas.spriteList)
                 {
                     sb.AppendLine(string.Format("name:{0}, coordinate:{1}", sprite.name, sprite.outer));
                 }  

                 sw.Write(sb.ToString());
                 sw.Close();  

                 string[] arg = new string[];
                 arg[] = atlasPng;
                 arg[] = th;
                 //print(arg[0]);
                 //print(arg[1]);
                 string path_2 = AssetDatabase.GetAssetPath(Resources.Load("CutAltas/output"));
                 FileInfo aFileinfo_2 = new FileInfo(path_2);
                 string th_2 = aFileinfo_2.DirectoryName;
                 print(th_2);
                 string s = th_2 + "\\Start.exe";
这是主要的代码，接下来用vs编写一个程序切割图集，主要代码如下
[csharp] view plaincopy
namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        string[] p;
        string path = string.Empty;
        public Form1(string[] s)
        {
            InitializeComponent();
            p = s;
            ImageName.Text = p[];
            path = p[];
        }  

        private void button1_Click(object sender, EventArgs e)
        {
            CutImage(path);
            Application.Exit();  

        }  

        void CutImage(string p)
        {
            string path=@"c:\Documents and Settings\Administrator\桌面\";
            string savePath=string.Empty;
            string imagePath = p + "\\"+ImageName.Text;
            string textPath = string.Empty;
            Image img = Image.FromFile(imagePath);  

            char[] c = { '.' };
            string st= ImageName.Text;
            string[] sts = st.Split(c);
            savePath = path + sts[];
            if (!Directory.Exists(savePath))
            {
                Directory.CreateDirectory(savePath);
            }
            textPath = p + "\\"+sts[]+".txt";
            StreamReader sr = new StreamReader(textPath);  

            while (!sr.EndOfStream)
            {
                string newLine = sr.ReadLine();
             //   Regex reg = new Regex(@"name:(?P<name>.+), coordinate:\(x:(?P<x>\d+)\.00, y:(?P<y>\d+)\.00, width:(?P<width>\d+)\.00, height:(?P<height>\d+)\.00\)");
             //   Regex regName = new Regex(@"\bname:\.*");
                string patternName = @"\bname:\w*";
                string patternX = @"\bcoordinate:\(x:\w*\.\d\d";
                string patternY = @"\by:\d*\.\d\d";
                string patternWidth = @"\bwidth:\d*\.\d\d";
                string patternHeight = @"\bheight:\d*\.\d\d";
                string name = savePath+"\\";
                float x=,y=,width=,height=;
                char[] maoHao = { ':' };  

                MatchCollection imageName = Regex.Matches(newLine, patternName, RegexOptions.ExplicitCapture);  

                foreach (Match nextMatch in imageName)
                {
                    int index = nextMatch.Index;
                    string result = nextMatch.ToString();  

                    string[] re = result.Split(maoHao);
                    name += re[re.Length - ];
                    name += ".png";
                  //  MessageBox.Show(re[1]);
                }
                MatchCollection positionX = Regex.Matches(newLine, patternX, RegexOptions.ExplicitCapture);
                foreach (Match nextMatch in positionX)
                {
                    int index = nextMatch.Index;
                    string result = nextMatch.ToString();  

                    string[] re = result.Split(maoHao);
                    x = float.Parse(re[re.Length - ]);
                //    MessageBox.Show(x.ToString());
                }
                MatchCollection positionY = Regex.Matches(newLine, patternY, RegexOptions.ExplicitCapture);
                foreach (Match nextMatch in positionY)
                {
                    int index = nextMatch.Index;
                    string result = nextMatch.ToString();  

                    string[] re = result.Split(maoHao);
                    y = float.Parse(re[re.Length-]);
                //    MessageBox.Show(y.ToString());
                }
                MatchCollection widths = Regex.Matches(newLine, patternWidth, RegexOptions.ExplicitCapture);
                foreach (Match nextMatch in widths)
                {
                    int index = nextMatch.Index;
                    string result = nextMatch.ToString();  

                    string[] re = result.Split(maoHao);
                    width = float.Parse(re[re.Length - ]);
                //    MessageBox.Show(width.ToString());
                }
                MatchCollection heights = Regex.Matches(newLine, patternHeight, RegexOptions.ExplicitCapture);
                foreach (Match nextMatch in heights)
                {
                    int index = nextMatch.Index;
                    string result = nextMatch.ToString();  

                    string[] re = result.Split(maoHao);
                    height = float.Parse(re[re.Length - ]);
                 //   MessageBox.Show(height.ToString());
                 //   MessageBox.Show("Name: " + name + "x :" + x.ToString() + "y :" + y.ToString() + "width :" + width.ToString() + "height :" + height.ToString());
                }
            //    MessageBox.Show("Name: "+name+"x :"+x.ToString()+"y :"+y.ToString()+"width :"+width.ToString()+"height :"+height.ToString());
                Bitmap bmp = new Bitmap(img);
                Rectangle rec = new Rectangle((int)x, (int)y, (int)width, (int)height);
                bmp = bmp.Clone(rec, bmp.PixelFormat);
                bmp.Save(name, System.Drawing.Imaging.ImageFormat.Png);
            }  

            MessageBox.Show("切割完成，返回桌面查看！");
        //    Bitmap bmp = new Bitmap(img, 100, 100);
          //  bmp.Save(path + "newImage.jpg");
        }
    }
}
最后unity要调用vs生成的程序，并且传进参数
static bool StartProcess(string filename, string[] args)
    {
        //print("wwww");
        try
        {
            string s="";
            foreach(string arg in args)
            {
                s += string.Format("\"{0}\" ", arg);
            }
            s = s.Trim();
            print(s);
            Process myprocess = new Process();
            ProcessStartInfo startInfo = new ProcessStartInfo(filename,s);
            myprocess.StartInfo = startInfo;
            myprocess.StartInfo.UseShellExecute = false;
            myprocess.Start();
            return true;
        }
        catch (Exception ex)
        {
            UnityEngine.Debug.Log("出错原因：" + ex.Message);
        }
        return false; 

    }
