Error While converting Presentation slides to Image


While converting Presentation to Image using ConvertToImage(ExportImageFormat.Jpeg) , for one of the slides I am getting the following error.

  Message=Object reference not set to an instance of an object.
   at Syncfusion.Presentation.TableImplementation.Table.UpdateHeightOfRow(Int32 rowIndex, Single height)
   at Syncfusion.Presentation.TableImplementation.Table.Layout()
   at Syncfusion.Presentation.SlideImplementation.Slide.Layout(Shape shape)
   at Syncfusion.Presentation.SlideImplementation.Slide.Layout()
   at Syncfusion.Presentation.SlideToImageConverter.SlideToImageConverter.ConvertToImage(ISlide slide, ExportImageFormat imageFormat)
   at PptToImage.Program.Main(String[] args) in C:\PptToImage\Program.cs:line 36

Note : The slide contains table with some data, When I tried removing few values from the table , then it worked fine.
Is there any limit on the size of data, allowed  on a slide that can be convert to image?
