Take photo in unity
Hey, I'm trying to build a program that takes your photo and places it with a different background, like a monument or so. So far, I was able to turn the camera on when I start the project with this code
webcamTexture = new WebCamTexture();
rawImage.texture = webcamTexture;
rawImage.material.mainTexture = webcamTexture;
webcamTexture.Play();
Texture2D PhotoTaken = new Texture2D (webcamTexture.width, webcamTexture.height);
PhotoTaken.SetPixels (webcamTexture.GetPixels ());
PhotoTaken.Apply ();
However, I can't take a screenshot or photo because it always ends up all black. I've tried different codes but nothing is working. Can someone please help? Thanks
Try
RenderTexture PhotoTaken = new RenderTexture(webcamTexture.width, webcamTexture.height,0); Graphics.Blit(webcamTexture,PhotoTaken);
After that, convert the RenderTexture to Texture2D to save it.
I have this now, and it takes the screenshot, but it's all white:
void Start () {
webcamTexture = new WebCamTexture();
rawImage.texture = webcamTexture;
rawImage.material.mainTexture = webcamTexture;
webcamTexture.Play();
RenderTexture PhotoTaken = new RenderTexture(webcamTexture.width, webcamTexture.height,0);
Graphics.Blit(webcamTexture, PhotoTaken);
}
void Update(RenderTexture source) {
var width = 400;
var height = 300;
RenderTexture.active = source;
Texture2D texture = new Texture2D(width, height, TextureFormat.ARGB32, false);
texture.ReadPixels(new Rect(0, 0, width, height), 0, 0);
texture.Apply();
Texture2D PhotoTaken = new Texture2D (width, height);
// Encode texture into PNG
var bytes = PhotoTaken.EncodeToPNG();
Destroy(PhotoTaken);
File.WriteAllBytes(Application.dataPath + "/../SavedScreen.png", bytes);
}
