How to give System.Drawing.Image data to System.Windows.Media.ImageSource (WPF) to display?

Question

Hi,

Can i get help on how to or can we give System.Drawing.Image data to a System.Windows.Media.ImageSorce in WPF/Xaml.

Basically I'm trying to display list of controls in my WPF application toolbox having images/icons in respective ToolboxBitmapAttribute . GetImage() method of ToolboxBitmapAttribute class gives me back a System.Drawing.Image, which cannot be directly set to System.Windows.Media.ImageSource. And that's the problem.

I do have an alternative ( or a hack  ) by writing the image to a file on the disk and give that path to my ImageSource (Yes, My application is a windows/desktop based application). But it looks like a desperate move and I don't want to do that.

Any better or correct way would really help. Thank You.

Hi Anil,

I answered a similar question yesterday... I dont know if there's a better way to do it, but you can make it a bit less hacky (and far more performant) by writing the image to a memory stream and not the file system.  The performance seems totally acceptable for the scenario I tried.  You'd want to do something like:

 

 

 

// Winforms Image we want to get the WPF Image from...

System.Drawing.Image imgWinForms = System.Drawing.Image.FromFile("test.png");

 

// ImageSource ...

BitmapImage bi = new BitmapImage();

bi.BeginInit();

MemoryStream ms = new MemoryStream();

// Save to a memory stream...

imgWinForms.Save(ms, ImageFormat.Bmp);

// Rewind the stream...

ms.Seek(0, SeekOrigin.Begin);

// Tell the WPF image to use this stream...

bi.StreamSource = ms;

bi.EndInit();

 

 

HTH.  Let me know if you figure out something less hacky, I'd love to know since this question has come up more than once...
