olivier the problem with transparency is that it often depends on the printer driver (no joke) I once asked the people from omingraffle and they told me that there is no standard. Stef Le 11/1/15 21:23, olivier auverlot a écrit :
In fact, the PNG is converted to JPEG image before to be included in the PDF file. But the conversion process doesn't support transparency and sets a black background. I think that is a limitation in the JPEG writer but someone have perhaps an idea to fix it.

Thanks - but that was not my question. PNG graphics format can - but must not include transparency. When I understand the mail correct only non-transparent PNG images are supported with the new addition.
That's why I ask about transparent PNG.
