Merge pull request #4244 from stweil/buildfix 
Use AM_CPPFLAGS also for compilation of all sources
 2024-05-19 20:47:31 +02:00
Stefan Weil
d72567ad45 Use AM_CPPFLAGS also for compilation of all sources 
It was not used for all sources before. Therefore some parts of the
code (especially the code for training) used different compiler
options. For example NDEBUG was not defined, and so the training
code was built with debug assertions (resulting in potentially
slower execution).

Fix FP exception in Wordrec::angle_change (issue #4242) (#4243) 
std::asin only allows arguments in [-1, 1], but rounding errors can
produce values which are slightly outside of this range and which
would cause a FP exception (or wrong calculation results).

Rename also the internally used function `TPOINT::length` to `TPOINT::length2`
because it calculates the square of the length.

Improve CCUtil::main_setup (fixes issue #4230) 
Conda installations patch TESSDATA_PREFIX in the binary.
That does not work for std::string because the length
won't be patched, so use a normal C string which can be
patched.

Simplify also the code which checks the last character
of datadir.

577e8a8b93 Add PAGE XML renderer / export (#4214) 
Add PAGE XML export and documentation.
To generate PAGE XML output just add 'page' to the tesseract command.

The output is outputname + '.page.xml' to avoid conflicts with ALTO export.

The output can be customized with the flags:
tessedit_create_page_polygon and tessedit_create_page_wordlevel.
