Answer 1

in xaml define a image:

<Image x:Name="imageElement" />

and in code

FileOpenPicker picker = new FileOpenPicker();
picker.FileTypeFilter.Add(".png");
var file = await picker.PickSingleFileAsync();
BitmapImage image = new BitmapImage();
IRandomAccessStream ram = await file.OpenAsync(FileAccessMode.Read);
await image.SetSourceAsync(ram);
imageElement.Source = image;

Hi,

I think you can begin with the XAML images sample
http://code.msdn.microsoft.com/windowsapps/0f5d56ae-5e57-48e1-9cd9-993115b027b9
Scenario4

You can try the PixelDataProvider Class

To operator the Pixel in Image.

Best regards,
Jesse
