James R. Barlow 9bb6fa04cb Return logging to a semblance of normalcy 2016-02-08 00:09:31 -08:00
James R. Barlow afb6f6f5c9 Render preview as .jpg instead of .png 
Smaller file size of JPEG seems to help performance, although the
difference is only about 1%.

James R. Barlow fe89232a30 Fix autorotate for some lossless cases 2016-02-07 05:59:46 -08:00
James R. Barlow 4b51b521e2 Implement autorotate (provided lossless reconstruction is disabled) 
Works for a single page file, probably

Although arguably rotation is not quite lossless, and the two could be
mutually exclusive anyway, so maybe this is it. Did not check in some
debugging changes (lossless=False, text debugging=True)

PyPDF seems to get merging wrong when one of the pages is rotated.

James R. Barlow 54b0ddd787 ghostscript: don't try to "help" autorotation 
It uses text direction alone -- unreliable guide.

James R. Barlow 599d889703 Implement "perfect reconstruction" - transfer page and watermark OCR layer 
Works, does not account for changes to clean/deskew, etc.
Surprisingly, it works. PyPDF2 fixes since last attempt?

James R. Barlow b485a1ef78 Override ruffus' handling of --jobs 
Ruffus treats omitted parameter as -j1. For our purposes it makes more
sense for omitting the parameter to mean "use all CPUs". As such we
must be able to distinguish -j1 from the parameter -j being omitted.

Telling ruffus to ignore the argument actually just makes it not auto
generate the argument. We can add an argument back with the same name.

James R. Barlow 61b3ccb57c Place ruffus database in temporary folder 
Because we don't really use ruffus checkpoint feature, putting the
database in a permanent location does not help anything, but does cause
large database files and problems if the .ruffus_history.sqlite wanted
to be in a writable location.

James R. Barlow 276f421c44 Did a quick test of Ghostscript vs QPDF at PDF page splitting 
qpdf won so hard it wasn't funny, even though it must be called once
per page to do the job. Perhaps Ghostscript interprets it as a call to
render the page?
