Chart to bitmap

[Vladimir]

Hi Telerik Team,

Thanks again for the work you have been doing.

I have a data series that is used to display a chart in the app.
I would like to render this data series into bitmap but I don't wanna to show the new chart.(It is a little bit different)
Finally I would like to generate a Bitmap on the fly and upload it to the Skydrive.
What Is the best way to achieve this?

best regards,
Vladimir.

Hello Vladimir,

You can use WriteableBitmap to create a snapshot of your chart like this:

WriteableBitmap bmp = new WriteableBitmap(this.chart, null);
bmp.Invalidate();
bmp.SaveJpeg();

For more info on how to use SaveJpeg() see here.

Hi Victor,

Thanks for the answer.
The things is that I don't have a UI chart control.
I only have the dataseries and want to generate chart in memory and save it into a bitmap file.
Is it possible?

Regards,
Vladimir.

Hi Vladimir,

Yes, of course, you don't need any xaml to create the chart. Just initialize a RadCartesianChart object in C# and use WriteableBitmap to render it to a bitmap.
