Captures a photo from the web camera and stores it in memory or on disk.
Demonstrates how to take a photo using the PhotoCapture functionality and display it on a Unity GameObject.
using UnityEngine; using System.Collections; using System.Linq; using UnityEngine.Windows.WebCam;
public class PhotoCaptureExample : MonoBehaviour { PhotoCapture photoCaptureObject = null; Texture2D targetTexture = null;

SupportedResolutions | A list of all the supported device resolutions for taking pictures. |
Dispose | Dispose must be called to shutdown the PhotoCapture instance. |
GetUnsafePointerToVideoDeviceController | Provides a COM pointer to the native IVideoDeviceController. |
StartPhotoModeAsync | Asynchronously starts photo mode. |
StopPhotoModeAsync | Asynchronously stops photo mode. |
TakePhotoAsync | Asynchronously captures a photo from the web camera and saves it to disk. |
CreateAsync | Asynchronously creates an instance of a PhotoCapture object that can be used to capture photos. |
OnCapturedToDiskCallback | Called when a photo has been saved to the file system. |
OnCapturedToMemoryCallback | Called when a photo has been captured to memory. |
OnCaptureResourceCreatedCallback | Called when a PhotoCapture resource has been created. |
OnPhotoModeStartedCallback | Called when photo mode has been started. |
OnPhotoModeStoppedCallback | Called when photo mode has been stopped. |
