or download here the .exe file

If you have any problem downloading the executable file, download the .zip that contains the PyAeroCounter.exe

./dist/PyAeroCounter.zip

This standalone application requires MikTeK and Tesseract OCR in order to execute properly, see item 3 of this file.

When the download is complete, it is recommended to create a folder and move the downloaded file to it.

2) PyAeroCounter.exe default inputs and outputs

It is necessary to place the .pdf file you want to count in the folder created earlier, together with the PyAeroCounter.exe file

PyAeroCounter.exe default input is to read a PDF document named 'pdffile.pdf'.

The default outputs include a log file containing the final result as well as text files with the extract text.

PyAeroCounter.exe also extract images from the PDF document and save them into 'PDFFILE' folder.

To start counting, just run the PyAeroCounter.exe file and wait for it to finish counting. When the console closes, the count is finished and the logfile.txt file can be opened to check the count values.

For different options, use the command line:

Example 1:

PyAeroCounter.exe -i EXAMPLE.pdf -d EXAMPLE_IMAGES
