Using Isolated Storage Images in the HubTiles - isolatedstorage

Question

I let the users take images in my app and save the images in the Isolated Storage. I also use HubTiles in my app but the HubTiles use a Uri in their Source property but it can't recognize the isostore:/..... Uris..
Any idea how can I fix this issue?

Answer 1

You are not the only one experiencing that the isostore:/ URIs are not functioning in every place an URI is expected. So it seems like you need to take the more traditional approach and load the image by hand:
// define data array to hold image data to be read from isolated storage
byte[] imageBytes;
using (IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
{
// open image file
using (IsolatedStorageFileStream fileStream = myIsolatedStorage.OpenFile("MyPreviouslySavedImage.jpg", FileMode.Open, FileAccess.Read))
{
// allocate array large enough to hold the whole file
imageBytes = new byte[fileStream.Length];
// read all data to memory
fileStream.Read(imageBytes, 0, imageBytes.Length);
fileStream.Close();
}
}
// create memory stream and bitmap
MemoryStream memoryStream = new MemoryStream(imageBytes);
BitmapImage bitmapImage = new BitmapImage();
// memory stream is source of bitmap
bitmapImage.SetSource(memoryStream);
// finally assign image to hub tile
hubTile1.Source = bitmapImage;
This works well (if there is an image in the isostore of course).
