We have the source version of TeeChart. I've just encountered an error whilst experimenting with trying to create a higher resolution image for reporting purposes.

The function we called was DrawToBitmap which generated the following exception:

"Please register your version of TeeChart to export to Bitmaps"

Is there something we need to do in order to create a license file with the source version. It was automatically generated when we had the binary release.

Regarding the image resolution issue. Is there a recommended approach to generating a higher resolution output image? We need it for reporting etc and the standard export methods produce quite a low res image.

Hi Loz,

We have been able to reproduce this issue using DrawToBitmap with latest TeeChart for .NET v3 source code version. We will fix this issue for the next source code release. In the meantime, being a sourcecode client, you can remove the DrawToBitmap implementation that throws this exception in TeeChart.

Regarding the resolution issue, DrawToBitmap is a .NET Framework, we recommend you to use TeeChart's built in exporting features. For further information please read Tutorial 12 - Exporting and Importing Charts. You'll find the tutorials at the program group created by the binary installer.

Thanks for the quick reply.

I expected I probably could just remove that code but was worried there may be other licensing issues.

I'll take another look at the tutorial.

Thank you.

Hi Loz,

No, there shouldn't be other licensing issues since the source code version doesn't include license control. Moreover, we tried removing this method with current sourcecode release and worked fine.
