Image with transparent background render issue when save in pdf format

Hi,

I use Aspose.Words for generate docx and pdf file dinamically.
These files are generated by pasting together several word documents and adding some parts dynamically by code.
In some cases, however, the images that have a transparent background (whether they are already present in other documents or added dynamically by code) are not rendered properly in pdf. The background from transparent becomes black. If I save in docx format che images are perfect.

See attachaments.

How can I render properly this images also in pdf?

Thanks.

Regards,
Davide
