Hii,

I have created a small effect using pixel shader and applied it to a image using WPF in c#.Everything works fine but now i am stuck with this final step. How to actually save the image ,after pixel shader effect is applied??

For E.g., I have applied a grayscale effect to a image in image control.Now I want to save it in some format, say jpeg. How to do it? moving further, I want to apply the same effect to a video also. I can manage to apply it but finally how to save that? Please some experts out there help me!!

Again I used WPF in c#... Thank you in advance!!

You can use following method to do the same for image rendering :-

public BitmapSource GetBitmapSourceFromVisual(FrameworkElement printCanvas)
{
RenderTargetBitmap renderBitmap = null;
try
{
System.Windows.Size size = new System.Windows.Size(printCanvas.Width, printCanvas.Height);

renderBitmap = new RenderTargetBitmap((int)(size.Width), (int)(size.Height), 96, 96, PixelFormats.Default);// PixelFormats.Pbgra32);

renderBitmap.Render(printCanvas);
return renderBitmap;
}
catch (Exception ex)
{
return renderBitmap;
}
}
