Thank you for contacting support.

Please note that the origin (0,0) of page is bottom left corner. Likewise, top left corner is (0,H) where H is the height of page. Moreover, basic measuring unit in Aspose.PDF for .NET is point, where 1 inch = 72 points. If you still think the coordinate value is incorrect then please share source file so that we may investigate accordingly. Also ensure using Aspose.PDF for .NET 19.11.

Thanks for the quick response. We will check it out and comeback, if required any further clarifications.
