pngtotxt is a simple bash script that is based on the Tesseract Open Source OCR Engine (main repository)

https://tesseract-ocr.github.io/

https://github.com/tesseract-ocr/tesseract

• tesseract: You can either Install Tesseract via pre-built binary package or build it from source. C++17 support is required for building.

• rename, zenity, imagemagick

  sudo apt install rename zenity imagemagick

Git clone this repo :

git clone https://gitlab.com/christosangel/pngtotxt.git

Change directory to pngtotxt:

cd pngtotxt

Make pngtotxt file executable:

chmod +x pngtotxt

You may copy this file to your /usr/local/bin if you like:

sudo cp pngtotxt/usr/local/bin/

In order to be able to convert images of text in specific languages :

1. Go to this link to see whether this specific language is supported by tesseract, and if yes,

2. Change /add lines to the pngtotxt script (lines 56 to 65), adding name and code of wanted language(s).

$ pngtotxt

Gather all the numbered images that you wish to convert at your desktop.

CAUTION: Remove all other irrelevant images from the desktop directory.

Images can be either png or gif.

Run pngtotxt, and you will be welcome with this message:

After you press Enter, you will be asked to give the name you wish for the final text:

After naming the final text, you will be asked for the language of the text:

After language selection, the conversion commences:

Finally, you get a message when the conversion is complete:

In the desktop you will find a folder named by the text name, that will contain:

1. The final text .txt file
2. an image scroll with the images concatenated.
3. a folder that contains all the png images.
4. a folder that contains all the txt files from the conversion.
