GDI+ error on conversion to Jpeg

I got “A generic error occurred in GDI+.” when trying to convert the sample Excel file to Jpeg. Please help to investigate. Thank you.

Environment: Aspose.Cells 22.3, .NET Core 6.0, CentOS 7

Sample: xlsx_sample.zip (596.0 KB)

Code sample:
using (var workbook = new Aspose.Cells.Workbook(inputFile))
var options = new ImageOrPrintOptions
OnePagePerSheet = false,
ImageType = ImageType.Jpeg,
PrintingPage = PrintingPageType.Default

foreach(var sheet in workbook.Worksheets)
var sr = new SheetRender(sheet, options);
for(int j = 0; j < sr.PageCount; j++)
var imgOut = $“Page_{j}”;
sr.ToImage(j, imgOut);


Thanks for the sample files.

Your issue might be due to environment problem, please confirm whether libgdiplus is installed under CentOS, it is required by the graphics library to render images. It can be installed by running the following command:

sudo yum install libgdiplus
cd /usr/lib
sudo ln -s libgdiplus.so gdiplus.dll

libgdiplus is indeed installed, conversion to Jpeg succeeded with other files. Can you please check again from your side?

Hi @dunghnguyen
We investigated and found that some special characters could not be drawn correctly under Linux by gid+,
We can only choose to skip these special characters to draw the whole picture. This will take effect in next version.
