Hello,

Thank you for your inquiry.

We have tested your document with such code :

ImageSaveOptions imageSaveOptions = new ImageSaveOptions();
imageSaveOptions.setSaveFileType(ImageSaveOptions.PNG);
imageSaveOptions.setAsListItems(true);
imageSaveOptions.setSavePath("save path");
ArrayList list;
imageSaveOptions.setSaveName("file_name");
imageSaveOptions.setSplitWorksheetIntoPages(false);
imageSaveOptions.setWorksheetIndex(1);
list = conversionHandler.convertToImage("path to file", imageSaveOptions);

and your document was converted well, as you can see on a screenshot.

Could you please share with us your code example of the conversion. Seems that you use incorrect configuration for Cells formats.

We will wait for your details.

Hello,


This is the code that I used:
ImageSaveOptions options = new ImageSaveOptions();
options.setSaveFileType(FileType.PNG);
options.setResolution(300);
options.setPage(pageNum);

Thank for you helping me solving the issue.

Hello,

Thank you for your code.

Please add this code line options.setWorksheetIndex(0) to your code . It should resolve your issue.

This parameter is required , because the Conversion library should know which worksheet it will convert.

If you will have more questions please feel free to contact us.
