Q:
I was hoping you
could help me understand the group begin and group end tags. Do they correspond to a particular token in
the PDF spec? I'm trying to figure out
if I can ignore them for my purposes or not, can I skip processing them, or do
they have some special sub elements I need to descend into to traverse the full
pdf content? I'm particularly interested
in extracting text and font information.

A:
Element::e_group_begin is same as 'q' operator (i.e. graphics state save)
Element::e_group_end is same as 'Q' operator (i.e. graphics state pop)
