Question

I have a WPF Image control with attached blur effect. Is there a way to save the image (with blur) without using RenderTargetBitmap?

Thank you.

UPDATE: I’m using now new custom effect which derives from System.Windows.Media.Effects.ShaderEffect. I would like to save my image with shader effect applied.

the only way you can render the bitmap is using RenderTargetBitmap.

Have a look at this example:

BitmapSource bitmap=GetYourBitmap(); Rectangle r=new Rectangle(); r.Background=new ImageBrush(bitmap); r.Effect=yourEffect;  Size sz=new Size(bitmap.PixelWidth, bitmap.PixelHeight); r.Measure(sz); r.Arrange(new Rect(sz);  var rtb=new RenderTargetBitmap(); rtb.Render(r); return rtb;//here is your bitmap with effects applied 

Hope this helps
