  1 +Document-level work
  2 +===================
  3 +
  4 +* See also issues tagged with "pages"
  5 +
  6 +* There is going to be a lot of duplicated code for doc-level stuff
  7 + between pages and split pages. That should be refactored. Perhaps
  8 + some kind of general method should be added to
  9 + QPDFPageDocumentHelper for copying a page from one file to another
  10 + and preserving document-level features. I will need to think about
  11 + how to make it efficient for bulk operations. Probably making it
  12 + work from qpdf.cc will be sufficient. I also need to think about how
  13 + to selectively turn on or off specific document-level features,
  14 + perhaps using flags or something.
  15 +
  16 +* Add flags to CLI to select which document-level options to
  17 + preserve or not preserve. We will probably need a pair of mutually
  18 + exclusive, repeatable options with a way to specify all, none, only
  19 + {x,y}, or all but {x,y}.
  20 +
  21 +* If a page contains a reference a file attachment annotation, when
  22 + that page is copied, if the file attachment appears in the top-level
  23 + EmbeddedFiles tree, that entry should be preserved in the
  24 + destination file. Otherwise, we probably will require the use of
  25 + --copy-attachments-from to preserve these. What will the strategy be
  26 + for deduplicating in the automatic case?
  27 +
  28 +* When I get to tagged PDF, note that the presence of /Artifact and
  29 + /Standard (and maybe others?) causes a false positive on detection
  30 + of unresolved names. Example: form-fields-and-annotations.pdf. This
  31 + used to give a warning (never in a released version), but the
  32 + warning was removed. See comments about tagged pdf in
  33 + QPDFPageObjectHelper::removeUnreferencedResourcesHelper. Another
  34 + potential solution is to recognize names that refer to fonts and
  35 + xobjects but only looking at names used with Tf and Do operators.
