Aspose cells usage leads to high cpu utilisation

Dear Team,


I am using aspose cells for thumbnail generation from xls file.It leads to high cpu usage.
Here is my code


Workbook workbook=new Workbook();
workbook.open(fis);
ImageOptions imagePrintOptions=new ImageOptions();
imagePrintOptions.setHorizontalResolution(100);
imagePrintOptions.setVerticalResolution(100);
imagePrintOptions.setImageFormat(ImageFormat.JPEG);
Worksheet workSheet=workbook.getWorksheets().getSheet(0);
SheetRender sheetRender=new SheetRender(workSheet,imagePrintOptions);
sheetRender.toImage(0,“excelthumbnail.jpg”);//No I18N


And our stack trace is

Hi,


Thank you for using Aspose products.

I believe you are using some older version of Aspose.Cells for Java release. I would request you to please try our latest version Aspose.Cells for Java v7.5.3.2 on your end and see if this works for you. In case you face the exception again, please share your sample excel file to replicate the problem on our end for rectification purposes.

Looking forward to your response.
