Hi Tom,

Thanks for your inquiry.

I was unable to reproduce this exception on my side. I would suggest you please upgrade to the latest version of Aspose.Words i.e. v11.0.0. Moreover, please read the following article on How-to: Migrate to Aspose.Words 10.5 or Higher:

Moreover, in case you want the pages of the document to be rendered as black and white images, please try using ImageColorMode property .

I hope, this will help.

Best Regards,
