Embedding PNGs in PDFs

Ruby
1

Hello,

is there a Ruby library for embedding PNGs and other images in existing
PDF files?

I’ve found Haru (http://libharu.sourceforge.net/) which seems to be
supported on many platforms, but I’d prefer to go with plain Ruby.

Greetings
Ralph

Does PDF Writer actually support manipulating existing PDFs? If I recall
correctly, it can only generate new ones.
