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 4a9e9e9db2 v4.5.3 release notes 2017-03-29 13:19:34 -07:00
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 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.

attention.

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.

James R. Barlow 18b6f05657 Resolve issue #124 - poor performance with Tesseract v4 
It seems that Tesseract v4 on a platform with OpenMP working correctly
while perform poorly with ocrmypdf because each will also soak up all
available CPUs. Running N^2 processes/threads on a N-core CPU where
each wants 100% of CPU turns out to be detrimental.

So, we restrict ocrmypdf w/tessv4 to a single Tesseract process at a
time, for now. Alternative may be to limit OpenMP threads if throughput
is higher.

James R. Barlow c42d9baa26 tesseract: for v4, use --psm while keeping -psm for v3 
At the moment v4 accepts both but who knows if this will get dropped,
so do as document for each version.
