Working with bitmap in WPF

Is there any sane way to work with bitmaps in WPF? I'd like similar functionality as System.Drawing.Bitmap: be able to load image from file and get and set the color of particular pixels.

I know about WriteableBitmap, but I don开发者_Go百科't want to work with Arrays of gods-know-what (I couldn't find that on MSDN), or pointers. I just want to read or write pixel, it shouldn't be that hard!

I also know that I can use Interop to work with System.Drawing.Bitmap in WPF, but that's not nice either.

Here's something on how to do get pixel info from a System.Windows.Media.Imaging.BitmapImage.

Although, if you'd prefer to work with a System.Drawing.Bitmap you might want to add a reference to System.Drawing.dll and use it instead.

Here's a somewhat-related forum post on image manipulation in WPF.
