Dear support:
I'm trying to convert a Excel chart to image with the following codes.
- Code: Select all
Workbook workbook = new Workbook();
workbook.LoadFromFile("test.xlsx");
Worksheet sheet = workbook.Worksheets[0];
if (sheet.Charts.Count > 0)
{
Image[] imgs = workbook.SaveChartAsImage(sheet);
}
It throw a NullReferenceException on this line: Image[] imgs = workbook.SaveChartAsImage(sheet),but sheet and workbook are not null.
please help,thank you.

Hello,
Thanks for your inquiry.
If you were using an old version, I suggest that you upgrade to the latest commercial version (
Spire.XLS Pack(Hotfix) Version:8.9.3) to have a test. If the issue still troubles you, please provide your Excel file so that we can do further investigations. You could send it to our email (
support@e-iceblue.com).
Sincerely,
Nina
