When using text2image for training, I get the error: Could not find font named... how can I know the correct name of a font?

[Ernesto Borio]

When using text2image for training, I get the error:

 

$ text2image --text=charset.txt --outputbase=[eng].[HeroicCondensedBoldRegular].exp0 --font='Heroic Condensed Bold Regular' --fonts_dir=.

(process:29818): Pango-WARNING **: couldn't load font "Heroic Bold Condensed", modified variant/weight/stretch as fallback, expect ugly output.

Could not find font named Heroic Condensed Bold Regular.

Pango suggested font Helvetica.

Please correct --font arg.

The font is Heroic Condensed Bold Regular

At least, that's the full name that MacOS returns when I get info on the font.

What's wrong here? Am I naming the font incorrectly?

I'm following this documentation:
https://github.com/tesseract-ocr/tesseract/wiki/Training-Tesseract#questions-about-the-training-process

Thanks!

You can check available fonts on your system by using --find_fonts with text2image, to find font names used by tesseract

example command with output - please modify path to match your setup

text2image --find_fonts --text ./langdata/eng/eng.training_text --outputbase ./langdata/eng/  --min_coverage 0.999  --fonts_dir=./fonts/
