在 hololens 应用程序中将图像保存到照片文件夹
Saving an Image to Photos Folder In hololens App
我正在尝试在我的 hololens 应用程序中拍摄照片。它似乎在工作,但将图像保存到一个我无法访问或查看的不起眼的地方。我想将它保存到我的图片库 Described here I think。或者我应该将图像保存在哪里,以便我可以在全息镜头上的照片中看到它。
filePath = C:/Data/Users/JanikJoe/AppData/Local/Packages/HoloToolkit-Unity_pzq3xp76mxafg/LocalState\CapturedImage10.02831_n.jpg
filePath2 = C:/Data/Users/DefaultAccount/AppData/Local/DevelopmentFiles/HoloToolkit-UnityVS.Debug_x86.janik/Data\CapturedImage10.02831_n.jpg
using UnityEngine;
using UnityEngine.VR.WSA.WebCam;
using System.Linq;
public class PhotoCaptureFVTC : MonoBehaviour {
UnityEngine.VR.WSA.WebCam.PhotoCapture photoCaptureObject = null;
// Use this for initialization
void Start()
{
Debug.Log("snap pic taken");
PhotoCapture.CreateAsync(false, OnPhotoCaptureCreated);
}
public void OnPhotoCaptureCreated(PhotoCapture captureObject)
{
photoCaptureObject = captureObject;
//Resolution cameraResolution = PhotoCapture.SupportedResolutions.OrderByDescending((res) => res.width * res.height).First();
Resolution cameraResolution = PhotoCapture.SupportedResolutions.OrderByDescending((res) => res.width * res.height).First();
CameraParameters c = new CameraParameters();
c.hologramOpacity = 0.0f;
c.cameraResolutionWidth = cameraResolution.width;
c.cameraResolutionHeight = cameraResolution.height;
c.pixelFormat = CapturePixelFormat.BGRA32;
captureObject.StartPhotoModeAsync(c, false, OnPhotoModeStarted);
}
void OnStoppedPhotoMode(PhotoCapture.PhotoCaptureResult result)
{
photoCaptureObject.Dispose();
photoCaptureObject = null;
}
private void OnPhotoModeStarted(PhotoCapture.PhotoCaptureResult result)
{
if (result.success)
{
string filename = string.Format(@"CapturedImage{0}_n.jpg", Time.time);
string filePath = System.IO.Path.Combine(Application.persistentDataPath, filename);
string filePath2 = System.IO.Path.Combine(Application.dataPath, filename);
photoCaptureObject.TakePhotoAsync(filePath, PhotoCaptureFileOutputFormat.JPG, OnCapturedPhotoToDisk);
Debug.LogError("Saved That Image Somewhere" +"FileName: ="+ filename + " FilePath: = " + filePath + " FilePath2: = " + filePath2);
}
else
{
Debug.LogError("Unable to start photo mode!");
}
}
void OnCapturedPhotoToDisk(PhotoCapture.PhotoCaptureResult result)
{
if (result.success)
{
Debug.Log("Saved Photo to disk!");
photoCaptureObject.StopPhotoModeAsync(OnStoppedPhotoMode);
}
else
{
Debug.Log("Failed to save Photo to disk");
}
}
}
好像是不能直接保存到相册文件夹,而且HoloLens上没有图片库。
这里有同样的问题:https://forums.hololens.com/discussion/1458/capturing-photo-in-unity-and-saving-to-disk
我尝试了解决方法,效果很好。只需将保存的图像移动到相机胶卷文件夹即可。
#if !UNITY_EDITOR && UNITY_WINRT_10_0
var cameraRollFolder = Windows.Storage.KnownFolders.CameraRoll.Path;
File.Move(_filePath, Path.Combine(cameraRollFolder, _filename));
#endif
