Dear Thao,

Thanks for your inquiry.
After an initial test with the latest version Spire.XLS Pack(Hotfix) Version:9.1.22, I can convert your Excel file to image successfully. Attached is my resultant image. If you were using an old version, I would suggest that you give the latest one a try. If the issue still occurs after trying, please provide your system configuration (E.g. Windows 7, 64-bit) along with the region setting (E.g. China, Chinese) for further testing.
My testing code is given as follows, if your code is different from mine, please also share it with us.

Code: Select all

Workbook wb = new Workbook();
wb.LoadFromFile(@"Business Process  Flowchart Revenue and AR.xlsx");
Worksheet sheet = wb.Worksheets[0];
Image image=sheet.ToImage(1, 1, sheet.LastRow, sheet.LastColumn);
image.Save("result.png", System.Drawing.Imaging.ImageFormat.Png);

Hi,

Thanks for your feedback.
The version I provided in previous post is our commercial version, which will produce the evaluation message without apply a valid license of Spire.XLS. Unfortunately, currently our latest free version (Free Spire.XLS for .NET Version:8.3) has a problem when converting your Excel to image. Sorry for the inconvenience. Since we don't update our free version regularly, I prefer to recommend that you keep using our commercial version, our sales team just sent you a one-month-free license via email to help remove the evaluation and better evaluate our commercial version. If there is any question, welcome to write back.

Dear Anindya,

Thank you for contacting us and sorry for late reply as weekend.
Our Spire.XLS supports converting Excel sheet to image directly, but we don't provide a method to capture image using webcam, which is not the category of our products and we don't have much knowledge about it, please look for the solution online. If you need other helps related to our products, just feel free to write back.

Sincerely,
Nina
