Conversion of Visio to PNG


1. Conversion of Visio to PNG

In word document, we have Visio drawing 6 and 11.
The diagram dll throws error during the conversion of Visio to PNG.
(ERROR:Visio files with versions below 11 are not supported. Please convert the file to Visio 2003/2007/2010 format.)

2. How to update the older version of visio(binary, VSD) to latest version of (VSDX) in word document?

The word document contains an Oleobject with the older version of Visio drawing(like Visio.Drawing.6 and Visio.Drawing.11). Programmatically we need to convert them into latest version of Visio drawing(VSDX).

We have attached the word document.

Please guide us in this regard.

Hi Raj,

Thank you for contacting support. Unfortunately, there is no way to convert the old Visio drawing 6 to the latest Visio format using Aspose.Diagram API. You can convert it manually using Microsoft Office Visio application.

In reference to the Visio drawing 11, we have tested DOCX file against the latest Aspose.Words and Aspose.Diagram 16.12.0 APIs. It throws a page out of index error while saving the VSD drawing into the PNG format. It has been logged under ticket ID DIAGRAMNET-51125 in our bug tracking system. Your post has also been linked to this ticket. We’ll keep you informed regarding any available updates. We’re sorry for the inconvenience caused.
