Set Image.Source from photo in camera roll - c#

In my Windows Phone 8.1 App i take a photo with the camera and save this in the camera roll and save the image path in a temporary object:
var picture = library.SavePictureToCameraRoll(fileName, e.ImageStream);
geophoto.ImagePath = picture.GetPath();
In another page of my app i want to load this photo from the camera roll and set the saved path as the source of an Image object:
Uri uri = new Uri(App.Current.Geophoto.ImagePath, UriKind.Absolute);
ImageSource imgSource = new BitmapImage(uri);
this.ShutterImage.Source = imgSource;
The saved path of the image is e.g. "file:///C:/Data/Users/Public/Pictures/Camera Roll/201506191442443805.jpg"
In runtime the image goes blank when i try to set a new source. Is there something wrong with the path or with the code?

I figured out that i have no direct access to camera roll through the path. So i solved my problem with the following code:
private BitmapImage GetThumbnailFromCameraRoll(string path)
{
MediaLibrary mediaLibrary = new MediaLibrary();
var pictures = mediaLibrary.Pictures;
foreach (var picture in pictures)
{
var camerarollPath = picture.GetPath();
if (camerarollPath == path)
{
BitmapImage image = new BitmapImage();
image.SetSource(picture.GetThumbnail());
return image;
}
}
return null;
}

Now I have a Shape in word,Can I turn it into a image and save it?

I'm trying to use ConvertToInlineShape().
But it is not successful,because it is a GroupShapes, its type is msoGroup.
How do I turn it into image and save as?
foreach (Microsoft.Office.Interop.Word.Shape s in WordDoc.Shapes)
{
if (s.Type.ToString() == "msoGroup")
{
//First try:
s.ConvertToInlineShape();
//Second try
s.Select();
WordApp.ActiveWindow.Selection.CopyAsPicture();
Image image = Clipboard.GetImage();
Bitmap bitmap = new Bitmap(image);
bitmap.Save("d:\\test" + i + ".jpg");
//image in null
}
}

Fast way to check is image exists in assets in Windows Phone

My application for Windows Phone 8.1.
I need to find a way to check image aviability in assets resources in my application.
At first, I had following solution:
var package = Windows.ApplicationModel.Package.Current.InstalledLocation;
var folder = await package.GetFolderAsync("Assets\\Makes");
var files = await folder.GetFilesAsync();
var result = files.FirstOrDefault(p => p.Name == imageName);
if (result != null)
{
Uri imageUri = new Uri("ms-appx:///Assets/Makes/" + imageName);
Image img = new Image();
BitmapImage bi = new BitmapImage(imageUri);
img.Source = bi;
btn.Content = img;
}
else
{
TextBlock label = new TextBlock();
label.Text = text;
btn.Content = label;
}
It works. But, unfortunately, very very slow.
Anyway, next part of code working even in case if asset is not existing:
Uri imageUri = new Uri("ms-appx:///Assets/Makes/" + imageName);
BitmapImage bi = new BitmapImage(imageUri);
In case if file not existing, the image is empty, but not null.
Is there are any good way, to check, if image created empty from resource?
Or a really fast way to check existing of packaged resource file?
Thank you

Getting NotSupportedException when trying to set image from isolated storage

I'm trying to set image for my tile in the background agent for my application:
ShellTile t = ShellTile.ActiveTiles.First();
if (t != null)
{
var filePath = Path.Combine("Tiles", "test1.jpg");
StandardTileData tile = new StandardTileData();
tile.Title = "Title text here";
tile.BackgroundImage = new Uri(#"isostore:\" + filePath, UriKind.Absolute);
t.Update(tile);
}
but then on t.Update(tile) it throws NotSupportedException :-( Isnt the path ("isostore:\") correct?
new Uri(#"isostore:" + filePath, UriKind.Absolute);
Without the backslash.

Not getting image from Persistant path in Android using unity3d

I have a script to take screenshot and save that image and to show that image in a plane.
But not getting that texture.
private string path;
void Start () {
path = Application.persistentDataPath;
}
void captureScreeshot(){
Application.CaptureScreenshot(path + "/Screenshot.png");
alert.text = "saved";
StartCoroutine(saveScreenshot());
onetimeBool = false;
}
IEnumerator saveScreenshot(){
WWW imgfile = new WWW("file://" + path+ "/Screenshot.png");
yield return imgfile;
if(imgfile.error==null){
img = new Texture2D(200, 200, TextureFormat.RGB24, false);
imgfile.LoadImageIntoTexture(img);
alert.text = "got image";
GameObject.Find("plane").renderer.material.mainTexture = img;
}else{
print(imgfile.error);
}
}
Images gets saved.
But I cannot open (load) image in system and android.
Getting error in system :
Couldn't open file /Users/ether/AppData/LocalLow/Company/Project/Screenshot.png
How to get it ???
This is because your path is wrong, you should use: application.dataPath, instead of Application.persistentDataPath.

displaying picture from local folder or from net

imagesHello -
I want to display a picture from a local folder in a picturebox, however if that picture fails to load, I woud like to download the image from a website and display it. I have no idea how to do this, but what I have is this:
try
{
pictureBox1.Image = System.Drawing.Image.FromFile("images\\" + filename + "_0001.gif");
XmlIn1.Close();
}
catch
{
string downloadPath = "http://www.website.com/images/" + filename + "_0001.gif";
pictureBox1.Image = System.Drawing.Image.FromFile(downloadPath);
XmlIn1.Close();
}
Why not use the ImageLocation property?
pictureBox1.ImageLocation = "http://skins.gmodules.com/ig/images/logos/approved/beveled_white.png";
Above code will display Google Logo from Web.
try something like
WebClient wc = new WebClient();
MemoryStream ms = new MemoryStream(wc.DownloadData(<imgURL>));
pictureBox1.Image = Image.FromStream(ms);
