Check the attached .vsd file and the output .png file. It seems that there is a problem with rendering text.
Hi Victor,Thanks for your inquiry. Could you please try it with latest Aspose.Diagram for .Net v2.9.0? Because I did not observe any problem with latest version. I have attached Output image file for your reference. Please visit the download page to get the latest version here:
Please let me know in case of further assistance or comments.
Thanks you right the problem was in old dll`s.
