Save Chart as an image on Hard Drive
I am looking for ways to save the output of a Chart control as an image on the hard drive. Is 开发者_JAVA技巧it possible in SL? as I am not sure so thought of putting a question here..
Thanks...
have a look here: Can I programmatically capture snapshot of a Silverlight User Control?
You can simply take a screenshot of your chart. If you want to put in on the HD with silverlight you need to open a SaveFileDialog. Then it is possible.
EDIT: If you want to save it in different formats use ImageTools. http://imagetools.codeplex.com/. If you use ImageTools you can get a stream like this:
var editBitmap = new WriteableBitmap(1024, 786);
editBitmap = new WriteableBitmap((int)(this.RenderSize.Width), (int)(this.RenderSize.Height));
editBitmap.Render(this, new MatrixTransform());
editBitmap.Invalidate();
var myImage = editBitmap.ToImage();
Stream stream = myImage.ToStreamByExtension("png");
Hope this helps.
BR,
TJ
