James R. Barlow b52eb95cf8 optimize: use pikepdf to save PIL images
Eliminates another usage of PyMuPDF in the main path.

James R. Barlow b06ef03aac pipeline: use the resolution of the OCR image rather than recalculating
(Recalculating would fail if the image is not centered.)

James R. Barlow 35cb416563 pipeline: remove fitz-based attempt to repair table of contents
Prior to unsplit, if we were rebuilding the PDF we'd lose the
table of contents. With unsplit we keep the original file and patch
the table of contents as necessary, adn that works fine.
This remaining bit of code from PyMuPDF actually damages the
table of contents and removing it fixes the test suite. G'bye.

James R. Barlow d5fb275e9e Travis: hack in qpdf appimage version
qpdf from appimage does not report its version with --version if renamed
or accessed via symlink. Use an environment variable to supply it
where needed.

MuPDF/fitz changed some font references to point to table of contents
entries, corrupting the page.  It no longer gets to save.

James R. Barlow 36a53a7b37 Weave: Unconditionally rotate and scale the text layerThis solves two issues. First, the text layer can end up being adifferent size, probably if the DPI is not an integer; scaling helps itfit slightly better. Second, other printable text on the page can end uphorizontally scaled or misaligned if we don't all of our drawing in aq/Q pair. 2018-05-10 19:03:31 -07:00
James R. Barlow 0a5982a902 PyMuPDF tweaks: don't clean
In MuPDF 1.13 clean might be unreliable, so explicitly don't do it,
even though it doesn't cause trouble in 1.12.
