tesseract-recognize's Issues

Error on building from source ... better documentation?

Won't build on Ubuntu 20.04

Documentation doesn't state any dependencies. If dependencies are required it makes sense to include that in the documentation/information provided. Assumptions are bad.

docker pull - manifest issues

Hi. Eager to try out your package. Getting the following errors from docker hub:

docker pull mauvilsa/tesseract-recognize
Using default tag: latest
Error response from daemon: manifest for mauvilsa/tesseract-recognize:latest not found: manifest unknown: manifest unknown

I can pull "normal" stuff from docker, so I don't think that's the issue.

Thanks

After compiling

I get now, when I run it:

./tesseract-recognize -o out.xml --oem 2 page.png

terminate called after throwing an instance of 'std::runtime_error' what(): PageXML.newXml: either pagens needs to be provided or a schema be loaded Aborted (core dumped)

This picture is

If you try it to parse this picture, do you get all the rows and columns? I have problems with the layout, that tesseract can detect the most, but for instance 'Hormones' it can't read.

Output option bug in tesseract_recognize_api.py

I think, I found a little bug in your python wrapper. In your curl sample is an output file named. The script tesseract_recognize_api.py places the value in the command, but forgets the -o (which seems to expected by tesseract-recognize.cc)

I received the following error

execution failed: command=/usr/local/bin/tesseract-recognize /DATA/img.png /DATA/img3.xml output=tesseract-recognize: error: only a single page xml allowed as input

The flag can be included in the value to workaround it like curl -s -X POST -H "Content-Type: application/json" -d '{"input_file":"/DATA/img.png","output_file":"-o /DATA/img3.xml"}' http://localhost:5000/tesseract-recognize

failed to install on osx 10.12.5

On macOS Sierra

install xcode for g++
brew install tesseract --all-languages
brew install leptonica

Here is the error after I ran cmake -DCMAKE_INSTALL_PREFIX:PATH=$HOME ..

Linker cant detect language

I ran into this error after installing the required libraries ob ubuntu 18.04.02. I googled around and tried in 'CMakeLists.txt' to set the language, but I have no idea, what I'm doing there and it didn't work. Can you help me?

`CMake Error at CMakeLists.txt:15 (add_executable):
Cannot find source file:

with --save-crops got error std::runtime_error: PageXML.crop: opaque_coords not implemented for __PAGEXML_LEPT__

On macOS Sierra

test_rec.xml is the file generated by tesseract-recognize.
tesseract-recognize test_rec.xml --save-crops got error:
