Saving chart image to file from ninjascript.

[GaryAlbers]

Disclaimer: I know this is not supported by NinjaTrader.
I would like to hear if there are any other developers who may have some insight.

I am using the following lines of code:

Bitmap bmp = new Bitmap(chartControl.ChartPanel.Width, 
					chartControl.ChartPanel.Height, 
					PixelFormat.Format16bppRgb555);
chartControl.ChartPanel.DrawToBitmap(bmp, chartControl.ChartPanel.ClientRectangle);
bmp.Save(fileName, ImageFormat.Jpeg);

When it runs, I do get an output file, but it always shows an empty picture.

Can anybody suggest how to make this code save a valid image of the chart?

BTW, the 3 lines of code above were found in some old ninjascript code I found that attached the image to an email. I just want to save it to a file.

Thanks,
Gary Albers

As a follow up to my question...

I discovered that the code works when run from a strategy, just not from an indicator.

I can work with that.

However, if any one knows how to make the code work from an indicator as well I would appreciate the information.

Thanks,

Did you ever find a solution? I'm looking to create a toolbar button (I can already do that), that will save a screenshot to a temp folder (your code), then FTP it to my site (using this FTP code below (haven't tested it yet, but I hear it works)).

WebClient myWebClient = new WebClient();

Uri ftp_path = new Uri("ftp://FTPLOGIN:[email protected]/file.txt"); // file.txt
myWebClient.UploadFile(ftp_path.ToString(), @"/temp/anyfile.txt"); // anyfile.txt - 

I'm not sure if I can create a toolbar within a strategy, but I know I can in an indicator, so I'm curious if you've made any progress on this idea.

Thanks!

I have no further info on saving a chart image from an indicator.

I have used the same code in both indicators and strategies to add tool bar items.

Thanks for the reply. I created an indicator and it seemed to grab the screen shot just fine. The only difference I see from the Image > Save As... functionality is it doesn't put a nice header telling the instrument and time frame, but it does produce a higher quality image doing this programmatically.

I went a few steps further to upload the screenshot to Imgur and put the returned URL into the clipboard for the user. A single click gets you a URL to your screenshot! Works perfect, except it seems to freeze Ninjatrader while it is processing and communicating with Imgur. I put a timeout of 4s so it doesn't get too out of hand.

Thanks,

I think you could do most of that work on a separate, short lived thread.

Do you have a code snippet of how to implement that?

Thanks!

How do you turn off chart trader so that i can run a ninjascript from the chart?

There should be an icon on the toolbar.
