c# - 屏幕截图捕获和显示

Question

我正在创建一个应用程序，我希望能够在其中存储屏幕截图，然后在之后显示它。我的代码运行良好，屏幕截图已存储并且似乎也被程序毫无问题地接收到。但是，它没有显示屏幕截图，这非常令人沮丧。这是我的代码:

void OnGUI(){
    if (GUI.Button (new Rect(940,y+25, Screen.width/30, Screen.height/14), Tex7)){
        Debug.Log ("Selfie-maker");

        folderPath = Application.persistentDataPath + "/screenshot.png"; 
        Application.CaptureScreenshot(folderPath);



        Debug.Log ("Screenshot number " + screenshotCount +" taken!");
        screenshotCount ++; 

    }
    if(GUI.Button (new Rect(940,y+65, Screen.width/30, Screen.height/14), Tex)){

        Debug.Log ("Anders");
        fileName = Path.Combine(Application.persistentDataPath, "screenshot.png");
        bytes = File.ReadAllBytes(fileName);
        screenshot = new Texture2D(0,0,TextureFormat.ATF_RGB_DXT1, false);
        screenshot.LoadImage(bytes);

        } 

    }

我希望我提供的信息足够了。如果没有，请随时询问。

Answer 1

尝试像这样加载图像:

string fullFilename = Path.Combine(Application.persistentDataPath, "screenshot.png");

然后，载入图片:

WWW www = new WWW(fullFilename);
Texture2D texTmp = new Texture2D(0,0,TextureFormat.ATF_RGB_DXT1, false);
www.LoadImageIntoTexture(texTmp);

这应该可以，我无法测试代码，因为我没有在这台电脑上安装 Unity。

代码取自此处，请不要犹豫!
