What's the descriptive technical terminology information professionals
use to distinguish the kind of pdf that can't be used with cut paste,
an image of the page of an article versus the format in pdf where it's
not an image of a page and can be used with the cut paste
mechanism?... What is the
I would just say image-based or text-based. Sorry if you wanted something
more hifalutin.
There is another level of granularity though, inasmuch as you can publish a
text-based PDF that attempts to prevent copy/paste. Like websites with
their javascript hacks, it isn't really secure, it just
I've also heard many people use the term searchable PDF for a text-based PDF.

I often employ the word 'raster', along with some other foul language, for any
PDFs that don't have manipulate-able text.

Generally PDFs are capable of displaying two types of information: Vector
and Raster.
Vector information is composed of lossless data that describes points,
smooth lines, gradients, and curves. Vector information is lossless and has
no native resolution, it can be infinitely scaled. Text data is
I should also remark that vector information and raster information may
exist in the same PDF file. For example, a PDF of a magazine or newspaper
will probably vector text and column borders while photography will be
raster at ~300dpi.

Neither vector nor raster information describes the actual embedded
_text_ we're talking about though. The stuff that lets you
copy-and-paste _text_ (not images), or search text. PDFs can also have
that. And even know what portions of a raster displayed image correspond
to what characters.

When will people realize that they should never use two simple words when
six technical terms will suffice?
