Generate box file for JPN_VERT?

[Seokbong Choi]

Hello,

I am a Japanese comic book fan. Recently, I come to learn about tesseract, which is awesome.

There are many challenges around Japanese - it has millions characters, so that millions of iteration are required to train.

Another challenge is vertical text. Most of comic books use vertical alignment for the text.

I am trying to train tesseract based upon JPN_VERT (I already successfully trained JPN).

However, I am not able to find a way to generate "box" file, which is aligned vertically to train JPN_VERT further.

Any idea?

Thanks in advance.

Greg.

I found myself.

Please see language-specific.sh

VERTICAL_FONTS(= \

    "TAKAoExGothic" \ #for jpn

    "TAKAoExMincho" \ #for jpn

    "WHAT_EVER_FONT_YOU_WANT_TO_ADD"

)

when you execute tesstrain.sh \

  --font_dir /usr/share/font

  --lang jpn

...

  --fontlist "WHAT_EVER_FONT_YOU_WANT_TO_ADD"

You will see the box file and tiff file where characters are vertically aligned.

Thanks!
