Any chance to get this update for Windows too? I'm trying to compile the wrapper, but without success because the library is old and the referenced packages have been deleted from mirrors. |

#1448 (comment):
libtesseract-dev
from the default source of Ubuntu 22.04 and 20.04 is still in 4.1.1, and the latest version provided by @AlexanderP 's PPA is 5.3.0Note any end user who using
libOpenCvSharpEx.so
will have to install the corresponding version oflibtesseract-dev
from PAA too even if they haven't any usages onOpenCvSharp.Text.OCRTesseract
sincelibtesseract.so.5
is not statically linked intolibOpenCvSharpEx.so
.I'm not touching windows build since not familiar with MSVC.
This also fixes #881
