When you get to the second half of the list, getAnnot(x) probably fails
because you don't have as many items in the list. You should either
traverse the annotation list in reverse order (from n_annots to 0), or
always remove annotation 0 in your "for" loop.

Dear All,
my code snip below suggests that ‘a.pdf’ is copied to ‘b.pdf’ AFTER
removing all annotations of a.pdf. However, b.pdf still contains all
annotations seen in a.pdf.
Am I missing something obvious here?
Thanks,
J.
