Thank you for your inquiry.
Autoshapes conversion has some known restrictions. For instance work art is converted as ordinary text, callouts and organizational charts are not supported. For the first two shapes which should be placed on the same vertical level we’ll consult with Aspose.Pdf Team. Each of them belong to inline canvases, they go one after another. But Aspose.Pdf in this case arranges second one in a new line.
Full support of all autoshapes is very difficult and time expensive. Usually we implement features related to autoshapes by demand. If you have some particular requirements we can consider them. Let’s be more specific. Of course the less you request the faster we’ll implement that.
