Sorry to ask a question like that but I can't found a good answer :/

What is the difference between BitmapImage and Bitmap?

I want to work with TIFF image with any one of them I have to work. I found some tutorial that works with BitmapImage and another that works with Bitmap.

System.Windows.Media.Imaging.BitmapImage is a specialized BitmapSource that is optimized for loading images using Extensible Application Markup Language (XAML).

System.Drawing.Bitmap is a encapsulates a GDI+ bitmap which consists of the pixel data for a graphics image and its attributes.

The first is used with WPF/Silverlight (XAML), the second is used with Windows Forms (WinForms).

  • System.Drawing.Bitmap is not specific to winforms, it can just as easily be used in asp.net, a WCF service, a windows service etc. – Ben Robinson Sep 05 '11 at 13:31

    But it's generally used in WinForms. Specially in the context of his question. The MSDN links should clarify the rest. – Claus Jørgensen Sep 05 '11 at 13:32

    Sorry but i think it is misleading, it is used for manipulating bitmap images, and is unrelated to winforms, hence the System.Drawing namespace – Ben Robinson Sep 05 '11 at 13:36
  • I disagree. With Silverlight/WPF you would use WriteableBitmap for manipulating bitmap images. So I find System.Drawing to be technology specific. – Claus Jørgensen Sep 05 '11 at 13:42

    Bitmap only encapsulates GDI+ native object. GDI+ is not specific to WinForms. BitmapSource uses completely new set of APIs – NoviceProgrammer Sep 05 '11 at 13:54

Bitmap is a general purpose class in System.Drawing which can be used to manipulate images. Whereas the BitmapImage class is more geared toward use in the XAML / WPF world.
