在silverlight中將writeablebitmap保存爲JPG

Question

我有一個writeablebitmap對象，我想將它保存爲silverlight中的JPG，我該怎麼做？

Answer 1

我也將WriteableBitmap的對象爲圖像作爲

WriteableBitmap bitmap = new WriteableBitmap(Width,Height); 

//一些位圖繪製

然後

Image imageFHR = new Image(); 
imageFHR.Source = bitmap; 
imageFHR.Height = Height; 
imageFHR.Width = Width; 
myCanvas.Children.Add(imageFHR);
