I've made the changes you've shown me but I'm still leaking memory.
Here is a snippit of code form my app - this is running at 30fps and I
update whenever I receive a new frame from my Video Camera
using( System.Drawing.Bitmap bmp = IMGManager.MainBitmap )
if (vidMain.Fill == null)
vidMain.Fill = new
IntPtr.Zero, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions()));
ImageBrush bmpSrc = vidMain.Fill as ImageBrush;
BitmapSource bsrc = bmpSrc.ImageSource as BitmapSource;
bsrc = null; //no dispose method.. how do i clean up?
IntPtr.Zero, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions());
I see a post on the MSDN forums quoting a simmilar issue - Our issue is
there is no visible way of manually disposing of the interopbitmapsouce http://forums.microsoft.com/MSDN/Sho...23409&SiteID=1 email@example.com
