[poppler] About pdf to image

[suzuki toshiya]

Hi,

I guess poppler should have something you want, at least
internally, because the bindings for other frameworks (Qt,
GLib, cpp etc) may deal with the images without creating/
cleaning temporary image files.

BTW, before searching such, I want to ask an off-topic question;
your target operating system does not support memory-based
file system?

Regards,
mpsuzuki
