when i call Capture2 Text with a .jpg of 2 Mb, i have the impression that the program hangs...
what is the maximum size ?
the command line from my application is :
cmd /C "C:\Program Files\Capture2Text\Capture2Text_CLI.exe" -i D:\DropBox\MgData\SOS\Talon\BV-24-TAP.JPG -b -o texte.txt
Anything wrong in that ?
thanks in advance for your help

    Thank you for providing a detailed description of the issue.

    The problem is that Capture2Text is unable to clean the rather busy background of that image resulting in a lot of noise that causes OCR to struggle. To see this for yourself, use the --debug and look at the "debug_enhanced.png" image that gets generated. Capture2Text works best for less complex images. In addition, Capture2Text is optimized for 96 DPI, so when attempting to OCR an image scanned with a high DPI, it may help to reduce the --scale-factor option from the defaut of 3.5 to something lower.

      Thanks for your response…

      Sad that this will not be my solution, glad that I (tried) to use it
      correctly…

      And again, thanks for your work…
