A PNG with transparency displays fine in PgS, but when the documented is printed or saved as a PDF the PNG becomes a black box.
This is still true in the latest version (188.8.131.52)

Alpha channel is now supported in PDF output, but care must be taken to use a PDF viewer which supports alpha channel images.

Opps. Fixed in PDF. PostScript flat out does not support alpha mask images.

Understood that PostScript doesn't, but is there no chance of outputting such that the black would instead by white (or some other workaround)?

Shame this system doesn't let you split the bug into two bugs. Guess I need a feature request for that...
I will add code to preblend the alpha masked image with white before outputting to PostScript in 184.108.40.206.
So PDF fixed in 220.127.116.11, and PostScript "hacked" in 18.104.22.168.
