Camera Screenshot on mobile full of noise
I want to take a screenshot using another camera in Unity. I have read some sample project and watched this video.
And now, I can take screenshot and save it somewhere when using Unity Editor. But when I build it into my Android devices, the images become full of noise.
The image is too large so please view the image in my post on StackOverflow.
Here is my code:
void Awake()
{
myCamera = GetComponent<Camera>(); // Camera is disable in the scene
myCamera.targetTexture = new RenderTexture(Screen.width, Screen.height, 24);
}
public void takeScreenShot(){
myCamera.enabled = true;
StartCoroutine(Capture());
}
IEnumerator Capture(){
yield return new WaitForEndOfFrame();
Texture2D result = new Texture2D(myCamera.targetTexture.width, myCamera.targetTexture.height, TextureFormat.RGB24, false);
myCamera.Render();
RenderTexture.active = myCamera.targetTexture;
Rect rect = new Rect(0, 0, myCamera.targetTexture.width, myCamera.targetTexture.height);
result.ReadPixels(rect, 0, 0);
byte[] byteArray = result.EncodeToPNG();
string filePath = Application.persistentDataPath + "/ScreenShot.png";
System.IO.File.WriteAllBytes(filePath, byteArray);
Debug.Log("ScreenShot saved to: " + filePath);
Destroy(result);
myCamera.enabled = false;
}
