SaveChartAsImage method problems

[blastdoman]

Good morning.

I am working with version 10.1.0 of FreeSpire.XLS and I have noticed that the SaveChartAsImage method only returns images up to the third sheet of the book. If I have charts from the fourth sheet, the method returns 0 elements. Is this an error or the behavior is as expected? I don't see sense in this version to create the sheets you want but this function only returns images of graphs only up to the third.

A greeting.

Hello,

Thanks for your inquiry.
I tested the following code with Free Spire.XLS for .NET Version:10.10 but did not encounter the issue you mentioned. To help us investigate further, please provide your input file. Thanks in advance.

Code: Select all

            Workbook workbook = new Workbook();
            workbook.LoadFromFile("ChartSample.xlsx");
            foreach (Worksheet sheet in workbook.Worksheets)
            {
                for (int i = 0; i < sheet.Charts.Count; i++)
                {
                    Image image = workbook.SaveChartAsImage(sheet, i);
                    image.Save(sheet.Name + "-" + i + ".png", ImageFormat.Png);
                }
            }

Sincerely,

I have upgraded to version 10.10 and the problem is still happening. I've attached the input file although I don't know if you'll be able to open it so it's commented here https://www.e-iceblue.com/forum/error-loading-with-loadfromfile-t9790.html and the reason why the issue SPIREXLS-3002 was opened.

Thanks.

Hello,

Thanks for your response.
Unfortunately, I'm unable to open your file with our Spire.XLS. Are you testing another file? If so, please provide the appropriate file that could reproduce your issue to help us investigate further. You could send it to us (support@e-iceblue.com) via email. Thanks in advance.

Also, I have attached my input file for you to test, all charts in that file can be saved successfully.
