the requirement of the font

[simbadu1999]

Is it necessary that the font I use must be a true type or an open type one? There is an error when I input a font made by other organizations into the get_chars_from_ttfs.py.

ps： the font I use is "xxxx.TTF" and there is a mistake, too. Is that illegal? THANKS!

Our code only treats '.ttf' files (ttf should be lower cases!).
If you still have problems after changing "TTF" to "ttf", please show the error message to me.
Thanks!

I found that my own ttf.sfontversion is #$ as shown in pic1, while your given ttf is [] as shown in pic2.

To correct the description above, the given ttf's sfontversion is "\x00\x01\x00\x00" ,which equals to" � ". Thus, the code judges the sentence is false and didn't raise the error, while my ttf's sfontversion is not in ("\x00\x01\x00\x00", "OTTO", "true"). So, may I delete the judgement sentence? THANKS!

1. Actually, I don't know well about the .ttf files, but the code I uploaded worked well for my font files.
   If you can define the available character list from the ttf file with your own method, it is okay to use that method.
   Please see here for the example.

2. I checked the mean of the rendered picture to filter blank images because there were some characters with blank images in my font files.
