Adding Graphic Image to Chart

[reach4thelasers]

Hey there.

I'd like to add a graphic watermark on my charts. I have a PNG, is there any way to add this? Or a way to generate the SharpDX vectors to render it?

Thank you

Kevin

Hello reach4thelasers,

Thanks for opening the thread.

This can be done using SharpDX and drawing an image within OnRender().

Although created for bitmaps and not PNG's, we do have sample code that you can reference for how to do this. I will attach the sample to my post.

Please let me know if I may be of further assistance.

Hi Jim,

I know it's been just over two years!

How would you go about converting the image to grayscale? I tried changing PixelFormat but SharpDX was giving me a formatting error. I had a look over at SOF and read SharpDx will not render Grayscale (8dpp ??), but instead I have to use a shader. Any help on that would be great.

Hello sim22,

This would be more of a general C# concept than NinjaScript related and beyond the complexity of what we can support.

I would suggest you continue to search the sites you've linked to for the answer.

Please let us know if you need a third party to assist you with this.

Thank you. Don't expect much and you won't be disappointed.

is that available for NT7?

Hello TazoTadoa,

We don't have an example for drawing bitmaps in NinjaTrader 7 and we do not offer support for using System.Drawing or the Plot method which would be the parallel to NinjaTrader 8's OnRender().

A client previously was asking about drawing bitmaps in NinjaTrader 8 in reference to a script that already does this for NinjaTrader 7. Their attached script may help you out further, so I'll include a link below.
