[Moonlight-list] BitmapSource dimension

[Tony Alexander Hild]

Hi,

I'm trying to implement the missing methods of WriteableBitmap, but I get stucked. Since WriteableBitmap must have a constructor public WriteableBitmap (BitmapSource source), I must know the dimension of source because WriteableBitmap permits pixel access. The current implementation, a pixel is accessed using Marshal.ReadInt32 direct on the indexer, but Silverlight 3 RTM change a little bit. Now, there is a property int[] Pixels.

Which the best way to cast from the buffer pointer to int[], due to security issues?
How can I get the dimension of a BitmapSource, since I have only the pointer to it? It seems that the implementation of BitmapSource is not complete.

Sorry about this silly question, but I started hacking moonlight yesterday only.

Tony
