James R. Barlow c8a4cbcf17 Fix test suite breakage after sidecar feature added 
Forgot to update tesseract spoofers to account for change in tesseract
parameters.  Also the change to outputting multiple files in the collate
steps affected how ruffus passes information into downstream consumers
of those files.

Jakub Wilkandjbarlow83 2846fb4e31 Remove misplaced flags from re.sub() call (#153) 
The 4th argument of re.sub() is maximum number of substitutions,
not flags.

Moreover, re.MULTILINE affects only semantics of ^ and $,
so it wouldn't have any effect on this regular expression.

James R. Barlow 7b7e3a3e03 Enable lossless reconstruction for —pdf-renderer tess4 where appropriate 2017-03-29 23:44:12 -07:00
James R. Barlow 1e7fbd4202 Fix issues with —pdf-renderer tess4 page skipping 
If tess4 renderer needed to skip OCR on a page it would end up
duplicating the page contents onto the new page, rather than creating
a blank OCR layer and placing it on the output page. This created
duplicated content in output files.

James R. Barlow 88ef2718f1 Reject high Unicode metadata at command line 
Ghostscript 9.21 does not seem to accept Unicode above U+FFFF. Previous
versions did, but it now exits with a rangecheck error (-15).

Reject on the command line for now. Complete fix would also need to
check input PDF’s metadata.

James R. Barlow e71e8ca3ad Workaround for GS VMerror -25 bug 
Avoid inserting docinfo keys that would be translated to null strings,
to avoid running afoul of

James R. Barlow 45e9257d6e Don’t use filename “pdfa_def.ps” for GS file 
At recommendation of Artifex people, don’t use the filename pdfa_def.ps
because if given without a full path Ghostscript will prioritize
searching its own resources over the current directory, and will pick up
 the example file pdfa_def.ps instead.  We used the full path anyway,
but this is a prudent defensive change to avoid odd Ghostscript behavior.

James R. Barlow 99afebd033 tesseract jobs_limit(2) 
At least on macOS with my quadcore performance improves with two
tesseracts in parallel (20% gain). Hard to say how this will affect
Linux, but stepping up to 2 jobs seems justifiable.
