Avatar Service in Windows Runtime

Question

Hello,

I am trying to use the Avatar Service and/or the File Upload Service to create and save profile pictures for my app's users on Windows Runtime 8.1 (both Windows Phone and Windows) but I do not exactly understand how to do this. I have a default picture stored as a .png file in my app package that I would like to set as the profile picture when creating a new user. The API call for CreateAvatar says it requires a System.IO.Stream object but I am not sure how to obtain this after I am able to get the file like this:

StorageFile defaultProfilePic = await StorageFile.GetFileFromApplicationUriAsync(new Uri("ms-appx:///profilePic.png"));

So what is the next step to provide this file as a stream to the App42 CreateAvatar API call?

Also Is there a full example which retrieves a file from storage and uploads it and manages avatars for a user on Windows Runtime?

Hi,

 

Please try this below method

 

public static async Task<Stream> GetPhotoFromSDCard(String Imageurl)

        {

            try

            {

                StorageFile imgFile = await StorageFile.GetFileFromPathAsync(Imageurl);

                using (Stream fileStream = await imgFile.OpenStreamForReadAsync())

                {

                    StreamReader reader = new StreamReader(fileStream);

                    reader.BaseStream.Seek(0, SeekOrigin.Begin);

                    //BitmapImage bmp = new BitmapImage();

                    //bmp.SetSource(reader.BaseStream);

                    return reader.BaseStream;

                }

            }

            catch (Exception e)

            {

                return null;

            }

        }

Thanks for the help. I have another question though, is there anyway to delete all the avatar's for a user using the management console? I have tried deleting the user but then when I re-create a user with the same user name and try to add an avatar with the same avatar name as before it says the name still exists. So is there a way to manage the avatar service?

Also, using the App42 SDK for Windows Runtime I cannot seem to delete any avatars as it does not seem to have the methods  avatarService.DeleteAllAvatars() or DeleteAvatarByName() when I access my Avatar Service object.
