Taking screenshot

Hi guys,
Hoping someone can point me in the right direction with this as i'm running out of ideas. I'm unable to take a screenshot or store it in a metro app. I've tried the normal Applicaiton.CaptureScreenshot code which results in:

Code (csharp):

1. about to send file over playerconnection C:/Projects/ProjectName/Export/ProjectName/bin/x86/Debug/AppX/Data/Test_1887.png  with length 71053
2. Failed to store screen shot

/edit/
Problem solved, i ended up trying ReadPixels (has some problem with this as well, where using a render texture didn't include OnGUI textures, and plain ReadPixels on a Texture2D resulted in black pixels).
Turns out i didnt yield a frame before reading pixels.

That being said, any idea why Application.CaptureScreenshot won't work?

 

So the code I'm using now to capture the screenshot is simply:

Code (csharp):

1.  
2. string filename = "Test_" + Random.Range(0, 9999) + ".png";
3.         string fullpath = "";
4.  
5.         yield return new WaitForEndOfFrame();
6.         Texture2D tex = new Texture2D(Screen.width, Screen.height, TextureFormat.RGB24, false);
7.         tex.ReadPixels(new Rect(0, 0, Screen.width, Screen.height), 0, 0);
8.         tex.name = "ScreenScrape";
9.         tex.Apply();
10.         byte[] bytes = tex.EncodeToPNG();
11.         Destroy(tex);

After I have the bytes, I'm using the data writer to write it to the pictures library:

Code (csharp):

1.  
2.  
3. private static async void _ByteArrayToBitmapImage(string fileName, byte[] byteArray)
4.         {
5.             //Find the pictures folder
6.             Windows.Storage.StorageFolder picturesFolder = Windows.Storage.KnownFolders.PicturesLibrary;
7.  
8.             var imageFile = await picturesFolder.CreateFileAsync(fileName, Windows.Storage.CreationCollisionOption.ReplaceExisting);
9.             var fs = await imageFile.OpenAsync(Windows.Storage.FileAccessMode.ReadWrite);
10.             var writer = new Windows.Storage.Streams.DataWriter(fs.GetOutputStreamAt(0));
11.             writer.WriteBytes(byteArray);
12.             await writer.StoreAsync();
13.             writer.DetachStream();
14.             await fs.FlushAsync();
15.         }

Hope that all came through fine. I'm currently on my phone

 

I'm getting the same error message when I try Application.CaptureScreenshot... any news on this?

 

Thanks! I'll give that a try tomorrow.

Update: using that folder works, thanks!
