'ptsize' is not respected when '--find_fonts' and '--render_per_font' are used

[Shreeshrii]

It is possible that this is by design and that the find_fonts feature is just to be used as a sample of what the different text faces look like.

$ ./text2tif --fonts_dir= --text ../langdata/san/san.training_text --font Kokila  --outputbase san.Kokila.exp0 --ptsize=32

Rendered page 0 to file san.Kokila.exp0.tif
Rendered page 1 to file san.Kokila.exp0.tif
Rendered page 2 to file san.Kokila.exp0.tif
Rendered page 3 to file san.Kokila.exp0.tif
Rendered page 4 to file san.Kokila.exp0.tif

creates the image at text of 32pt.

But when --find_fonts and --render_per_font is used --ptsize=32 does not have any effect and only one page is output at default size of 12 pt.

$ ./text2tif --fonts_dir= --text ../langdata/san/san.training_text  --outputbase san.exp-1 --ptsize=32 --strip_unrenderable_words --fontconfig_refresh_config_file=false --leading=32 --char_spacing=0.0 --exposure=-1 --find_fonts --min_coverage=.9 --degrade_image=1 --underline_start_prob=.05 --underline_continuation_prob=.01

Please note the first line in English (mingw64 is giving error regarding this line, I think)

Yes, I believe it's by design.

./text2tif --text=../langdata/eng/eng.training.txt --outputbase=../langdata/gen/eng --fonts_dir=/usr/share/fonts --find_fonts --min_coverage=1.0
ls ../langdata/gen | sed 's/eng.//' | sed 's/.tif//'

Or, even better:

./text2tif --text=../langdata/eng/eng.training.txt --outputbase=../langdata/gen/eng --fonts_dir=/usr/share/fonts --find_fonts --min_coverage=1.0 --render_per_font=false

This will produce 'eng.fontlist.txt' file.

I added the second command form to TrainingTesseract wiki page.

This will be very useful. Thanks!
