@lsl,

Please share your source and output files so that we can investigate it on our end and help you accordingly.

code.zip (5.8 MB)
I also upload an mp4 int the zip, you can see the wrong row height and worksheet.AutoFitRows() will show the hide rows

@lsl,

Thanks for the sample code, sample video and template file.

Please update your code as following, it will work fine as I tested:
e.g
Sample code:

var workbook = new Workbook(“fail_detail_statistics___sms__2018-07-11_.xlsx”);
Worksheet worksheet = workbook.Worksheets[0];
// Set the print area with your desired range
// Set all margins as 0
worksheet.PageSetup.LeftMargin = 0;
worksheet.PageSetup.RightMargin = 0;
worksheet.PageSetup.TopMargin = 0;
worksheet.PageSetup.BottomMargin = 0;

//
worksheet.AutoFilter.Custom(0, FilterOperatorType.Equal, 3);
worksheet.AutoFilter.Refresh();

AutoFitterOptions autofitterOptions = new AutoFitterOptions();
autofitterOptions.IgnoreHidden = true;
worksheet.AutoFitRows(autofitterOptions);

        // Set OnePagePerSheet option as true
        ImageOrPrintOptions options = new ImageOrPrintOptions();
        options.OnePagePerSheet = true;
        options.ImageType = ImageType.Jpeg;
        options.HorizontalResolution = 100;
        options.VerticalResolution = 100;
      
        // Take the image of your worksheet
   
        SheetRender sr = new SheetRender(worksheet, options);
        sr.ToImage(0, "ww.jpg");
        workbook.Save("123.xlsx");
        Process.Start("ww.jpg");
