Introduction
While developing , we need sometimes to convert the Image in many types then we can modify them as we want or to store them in a Database...
Using the code
1-Convert File to Byte[]
byte[] fileBytes = null;
if (file != null)
{
using (IRandomAccessStreamWithContentType stream = await file.OpenReadAsync())
{
fileBytes = new byte[stream.Size];
using (DataReader reader = new DataReader(stream))
{
await reader.LoadAsync((uint)stream.Size);
reader.ReadBytes(fileBytes);
}
}
}
2-Convert Byte[] to BitmapImage
using (InMemoryRandomAccessStream ms = new InMemoryRandomAccessStream())
{
using (DataWriter writer = new DataWriter(ms.GetOutputStreamAt(0)))
{
writer.WriteBytes((byte[])fileBytes);
writer.StoreAsync().GetResults();
}
var image = new BitmapImage();
image.SetSource(ms);
}
3-Convert Byte[] to Stream
Stream stream = new MemoryStream(fileBytes);
4-Convert Stream to WriteableBitmap
WriteableBitmap writimage = new WriteableBitmap(1, 1);
BitmapPixelFormat format = BitmapPixelFormat.Unknown;
writimage = await WriteableBitmapExtensions.FromStream(writimage, stream, format);
writimage.SetSource(ms);
5-Convert File to BitmapImage
BitmapImage bmpImage = new BitmapImage(new Uri(file.Path));

these conversions can facilitate your work , you will find what you need with only one page ;)
