Steema Central

I have demonstrated an undesirable behavior when copying a chart image to clipboard.

I was able to reproduce the issue with the Program Files\Steema Software\TeeChart for .NET v3\Examples\DemoProject\bin\ExecutableDemo\TeeChartNetExamples.exe in the Welcome !\Miscellaneous\Clipboard\Single Chart example.

The call to tChart1.Export.Image.Bitmap.CopyToClipboard();

works as expected the first time it is called. The problem comes when you resize the chart control. If you then try to copy to clipboard, the new size is not copied to the windows clipboard. The call produces an image that has the original size when you 1st copied to the clipboard. All attempts from that point result in the same sized image on the clipboard.

Steps to reproduce issue in the TeeChartNetExample:
1. Started the TeeChartNetExample application and make sure the application is NOT maximized.
2. Size the window so it is wider than it is tall
3. Pressed the Copy to Clipboard button
4. Paste into your favorite paintbrush type application
5. Now resize the window so it is taller than it is wide
6. Press the Copy to Clipboard button
7. Paste into your favorite paintbrush type application
8. Notice that the aspect of the image captured is not the current aspect of window. Instead it is still the original aspect used in step 2.

Hi Mike,

Thanks for reporting. I've been able to reproduce the issue here and added it (TF02012751) to our defect list to be fixed for future releases.

In the release notes

Image Export Width and Height not
always correctly reading Chart Width
and Height. Fixed.


It appears this issue was addressed, however I am still able to reproduce the issue.

The interesting thing is I can't reproduce the problem in the binary that is provided with the Binary installer. I can reproduce the problem in the version I compile with the latest source code provided which is version 3.5.3105.20151. I built using the Release configuration.

I have uploaded my sample project for your review. The file was called ChartSimple.zip

Very strange. Anyhow, the source will be being rebuilt either today or tomorrow for the latest maintenance release and I'll try to remember to check this one for you.

I just reproduced the problem with the binary built by steema, version 3.5.3146.24805

Using the "Copy" button on the ChartController toolbar, that is where I see the problem. If I go to the Editor dialog, Export tab, select "As Bitmap" press the Copy button. That seems to work every time.

I still think there is a bug when using the Chart Control "Copy" button. Changing the aspect ration of a chart after pressing the copy button once will not capture the current aspect of the chart if it has changed.

Hi Mike,

I haven't been able to reproduce the issue here using latest TeeChart for .NET v3 sources. Would you be so kind to let us know the exact steps we should follow to reproduce the issue here?

Thanks in advance.

Ran the "C:\Program Files\Steema Software\TeeChart for .NET v3\Examples\DemoProject\bin\ExecutableDemo\TeeChartNetExamples.exe" that came with TeeChart Pro .Net v3, version 3.5.3146.24805. I believe this is the latest release version.

1. go to Welcome !\Components\ChartController
2. Press the "Copy" button on the ChartController toolbar
3. go to Start Menu | Accessories | Paint
4. Paste the image from the clipboard into Paint
5. Resize the TeeChartNetExamples window to make the chart be taller than it is wide
6. Press the "Copy" Button on the ChartController toolbar
7. Open another instance of Paint
8. Paste the contents of the Clipboard into the Paint application
9. Notice that the image pasted is the 1st image from step 4 above and not the 2nd image from step 6.


I verified that if I launch the TeeChart Editor from the ChartController and go to the Export Section and press the "Copy" button there, that it the proper image is copied. It seems the problem is with the "Copy" button on the ChartController.

Hi Mike,

Thanks for the information.

I understood which is the exact problem and was able to reproduce the issue here and added it (TF02013344) to the list to be fixed.
