The pixel data.
Remarks
PixelDataProvider doesn't retain a copy of the pixel data after a successful call to this method. This means that subsequent calls to the method will fail.
If you are using the Windows Runtime C++ Template Library (WRL), you are responsible for releasing the underlying memory for the pixel data. Call CoTaskMemFree after you are done with the data. If you are using a language projection such as C# or C++/WinRT, memory management is handled automatically.
The return value is an array of 8 bit unsigned values. However, depending on the requested pixel format, the pixel data may represent another type. For example, if the pixel format is Rgba16, then each color value is a 16 bit unsigned integer that takes up two 8 bit elements of the array. You must convert the array to the correct type before you use it.
