Unity 로 컬 그림 가 져 오기 및 저장 후 사용

본 고 는 로 컬 폴 더 를 열 어 그림 을 가 져 온 다음 에 상대 적 인 경로 에 저장 하고 다시 호출 하 는 것 이 라 고 생각 합 니 다.
우선,로 컬 디 렉 터 리 를 열 고 경 로 를 가 져 옵 니 다:
 

/// 

    ///     
    /// 
    private void GetPather()
    {
        OpenFileName openFileName = new OpenFileName();
        openFileName.structSize = Marshal.SizeOf(openFileName);

        openFileName.filter = "    (*.jpg,*.png,*.bmp)\0*.jpg;*.png;*.bmp";
        openFileName.file = new string(new char[256]);
        openFileName.maxFile = openFileName.file.Length;
        openFileName.fileTitle = new string(new char[64]);
        openFileName.maxFileTitle = openFileName.fileTitle.Length;
        openFileName.initialDir = Application.streamingAssetsPath.Replace('/', '\\');//    
        openFileName.title = "    ";

        openFileName.flags = 0x00080000 | 0x00001000 | 0x00000800 | 0x00000008;

        if (LocalDialog.GetSaveFileName(openFileName))
        {
            texPath = openFileName.file;

            FileStreamLoadTexture();
        }
    }

그리고 가 져 온 이 경 로 를 통 해 그림 을 읽 습 니 다:

/// 

    ///        
    /// 
    private void FileStreamLoadTexture()
    {
        //          
        FileStream fs = new FileStream(texPath, FileMode.Open);
        byte[] buffer = new byte[fs.Length];
        fs.Read(buffer, 0, buffer.Length);
        fs.Close();
        originalTex = new Texture2D(2, 2);
        var iSLoad = originalTex.LoadImage(buffer);
        originalTex.Apply();
        if (!iSLoad)
        {
            Debug.Log("Texture     Texture  ");
        }
        GetTexture();
        File.WriteAllBytes(Application.dataPath + "\\Pictures//texture" + (sprites.Count).ToString() + ".png", originalTex.EncodeToPNG());
    }

그림 을 액세스 할 때 발표 수요 로 인해 폴 더 를 만 드 는 방식 을 사 용 했 습 니 다.
 
 

string dirPath = Application.dataPath + "/" + "Pictures";

        DirectoryInfo mydir = new DirectoryInfo(dirPath);
        if (!mydir.Exists)
            Directory.CreateDirectory(dirPath);

다음 에 폴 더 의 그림 을 읽 고 사전 에 저장 하 며 출력 rollview 에 grid 형식 으로 저장 하여 선택 적 으로 사용 합 니 다.
 
전체 코드 는 다음 과 같 습 니 다.
