Re: list_available_fonts.

[Sriranga(80yrs)]

Hello members,
Thanks to Nick for his patches for text2image - under issues - now works fine for kannada project - for me. Only  cheluvi font out of kannada fonts installed could not find by the program. I have successfully generated box/tif files(upto 47 pages at a time) using text2 image without using box editor - since box file generated are 100% correct. Anyway I am happy with wonderful text2image program.

 Attached  cheluvi.tff  for testing and find solution for my problem - for which i shall be thankful to you.

I am using only in unbuntu 14.04(daily build) and downloaded tesseract-ocr  r-1054.from SVN. 

With regards,

sriranga(80)

It could clearly be seen that "list_available_fonts"-  has listed font  'cheluvi Bold' also along with other fonts. I could not understand why program unable to  find font "Cheluvi Bold"? Where I made mistake? waiting for your valuable guidance.

How to add fonts(extra/missing, if any) to the "list_available_fonts"  - request for valuable solution

With Warmest Regards,

Hi Zdenko, I have this font, look at what I have on my system:


fone...@foneworxtest.foneworx.co.za:/usr/share/fonts/truetype$ cd dejavu/

Good day Zdenko, maybe I am misunderstanding this part.

with this command:


 text2image --text=training_text.txt --outputbase=eng.FiraSans-Italic.exp0 --font='TimesNewRomanBold' --fonts_dir=/usr/share/fonts/truetype/FiraSans

and on this directory with this files:

fone...@foneworxtest.foneworx.co.za:/usr/share/fonts/opentype/FiraSans$ ls
FiraSans-BoldItalic.otf   FiraSans-ExtraBoldItalic.otf   FiraSans-HairItalic.otf   FiraSans-Light.otf           FiraSans-ThinItalic.otf        FiraSans-UltraLight.otf

FiraSans-Eight.otf        FiraSans-Four.otf              FiraSans-LightItalic.otf  FiraSans-SemiBold.otf        FiraSans-UltraLightItalic.otf


is it not the file name referring to the font name? on the specified directory?

I am a bit confused here.

please help.

font name and font file are independet. E.g. font named "Abraca dabra" could have filename "123654987.ttf"
