cutting and pasting from a pdf - both text and image - is fairly easy

Under X I can drag my mouse over the _text_ in a pdf file. Then in an
xemacs window I can double click and the text is pasted in there. (A
very useful facility.)
How come ? Surely the text in the pdf file is not ascii ? Surely
even the text is stored as a "graphic" in the pdf file ?
I am obviously misunderstanding something.

PDF is just a stripped down and compressed version of PS. Thus, the
text is certainly copyable. It may not be stored directly in ASCII
format in the PDF (as in I am not sure if this is the case or not), but
it is accessible as some kind of text.
