Tutorial Mi Band 4/5 | How to modify Font file

[pizarro77]

Hi guys, I'm new, I tried to use this guide but I can't in any way install the pillow. Then I didn't understand if the font files are already modified (enlarged) or I have to do it after installing everything. Thanks for the help.

I created BMP font creator program in PHP language.
This will create font from TTF (font file) to 1bit Bitmap.

after hours of dealing with XAMPP, I finally converted a ttf font to bmp files, thanks a million for this useful application, (checked out the codes too, amazing job ! )

so now I have one question, in the file "font_array.txt", if we add other characters for other languages and their specific codes, then we can be able to convert any ttf file for any language to bmp files, correct ?

Yes.

 

[kavehhn]

Yes.

there's only one problem,
this text file is LTR, and when you try to write Persian/Arabic/Hebrew characters on it, it gets mixed up and it won't create working bmp files.

can you make it work for other languages too ?
maybe developing a simple UI to write UTF-8 codes and numbers and also the character inside it
in a txt files, writing RTL characters next to LTR characters, mixes everything up

I try to add your character and don't modify any code. It's can generate font without problem or I understand wrong.

This seems interesting but don't have the expertise to use it. I hate the notifications font (which is also used in other places like weather place name, etc) but the default UI font is fine. Do you guys have any font packs made using this tool that you could share? I think any replacement will do because the notifications font is just hideous.

I will create a tutoring how to use it.

Edit means that we have to edit the images like we do for customizing resources^^.(you will not understand until you know the basics of them

you have to forces language to herbew(or in short on the language file the developer has changed the lang. to herbew.
