Screenshot from code

[saltminer]

Hi,
is there a way to get a chart screenshot from code?
I've tried the following with ChartPanel.PanelsAreaRectangle but only get a black rectangle. The code is first called like this:

// have to invoke on the thread that owns the chart panel, otherwise THIS thread has no access
	            	ChartPanel.Dispatcher.Invoke(new System.Action(() => GetScreenShot(...);

private void GetScreenShot(...)
{
			System.Windows.Media.Imaging.RenderTargetBitmap renderTargetBitmap = new System.Windows.Media.Imaging.RenderTargetBitmap(ChartPanel.W, ChartPanel.H, (double)RenderTarget.DotsPerInch.Width, (double)RenderTarget.DotsPerInch.Height, PixelFormats.Default);
			renderTargetBitmap.Render(ChartControl.PanelsAreaRectangle); 

// etc

Cheers,
saltminer

Hello saltminer, and thank you for your question. I will leave this question up on the forums to see if any member of the community can help, as this is outside the scope of the support we can provide directly.

LOL, I am a NinjaScript consultant. I put this post in the wrong forum though; it is an NT8 question.

Hi Saltminer, you can check out the script i shared here, has screen shot code within.

It you can only access the screenshot of the active tab in the window unfortunately, I am hoping for a way to screenshot tab specific.
