Loss of transparency when printing a PDF file.

[JulienMalossane]

Hello,

We are trying to print pdf file which contains multiple overlapping images with transparency.

When we open the pdf with "Adobe Reader" for example, the preview looks good.

But when we print with "Spire.PDF" library, the print result is not good because the images included in the document lose their transparency.

If there are parameters to do that, could you please send us an example to do it ?

Thanks and Regards.
