public class PhotoCaptureExample : MonoBehaviour { PhotoCapture photoCaptureObject = null; Texture2D targetTexture = null;

// Use this for initialization void Start() { Resolution cameraResolution = PhotoCapture.SupportedResolutions.OrderByDescending((res) => res.width * res.height).First(); targetTexture = new Texture2D(cameraResolution.width, cameraResolution.height);

// Create a PhotoCapture object PhotoCapture.CreateAsync(false, delegate(PhotoCapture captureObject) { photoCaptureObject = captureObject; CameraParameters cameraParameters = new CameraParameters(); cameraParameters.hologramOpacity = 0.0f; cameraParameters.cameraResolutionWidth = cameraResolution.width; cameraParameters.cameraResolutionHeight = cameraResolution.height; cameraParameters.pixelFormat = CapturePixelFormat.BGRA32;

// Activate the camera photoCaptureObject.StartPhotoModeAsync(cameraParameters, delegate(PhotoCapture.PhotoCaptureResult result) { // Take a picture photoCaptureObject.TakePhotoAsync(OnCapturedPhotoToMemory); }); }); }

void OnCapturedPhotoToMemory(PhotoCapture.PhotoCaptureResult result, PhotoCaptureFrame photoCaptureFrame) { // Copy the raw image data into our target texture photoCaptureFrame.UploadImageDataToTexture(targetTexture);

// Create a gameobject that we can apply our texture to GameObject quad = GameObject.CreatePrimitive(PrimitiveType.Quad); Renderer quadRenderer = quad.GetComponent<Renderer>() as Renderer; quadRenderer.material = new Material(Shader.Find("Custom/Unlit/UnlitTexture"));

quad.transform.parent = this.transform; quad.transform.localPosition = new Vector3(0.0f, 0.0f, 3.0f);

quadRenderer.material.SetTexture("_MainTex", targetTexture);

// Deactivate our camera photoCaptureObject.StopPhotoModeAsync(OnStoppedPhotoMode); }

void OnStoppedPhotoMode(PhotoCapture.PhotoCaptureResult result) { // Shutdown our photo capture resource photoCaptureObject.Dispose(); photoCaptureObject = null; } }

Static Variables

SupportedResolutionsA list of all the supported device resolutions for taking pictures.

Public Functions

DisposeDispose must be called to shutdown the PhotoCapture instance.
GetUnsafePointerToVideoDeviceControllerProvides a COM pointer to the native IVideoDeviceController.
StartPhotoModeAsyncAsynchronously starts photo mode.
StopPhotoModeAsyncAsynchronously stops photo mode.
TakePhotoAsyncAsynchronously captures a photo from the web camera and saves it to disk.

Static Functions

CreateAsyncAsynchronously creates an instance of a PhotoCapture object that can be used to capture photos.

Delegates

OnCapturedToDiskCallbackCalled when a photo has been saved to the file system.
OnCapturedToMemoryCallbackCalled when a photo has been captured to memory.
OnCaptureResourceCreatedCallbackCalled when a PhotoCapture resource has been created.
OnPhotoModeStartedCallbackCalled when photo mode has been started.
