arizuu / ttf2ugui Goto Github PK

Dear AriZuu,
When I use ugui, I can't support simplified Chinese. I try to use ttf2ugui to convert font, and I can't convert Chinese to C array. Do you have any good suggestions?
Thank You。

I'm trying to use the tool to convert fonts, but get errors when I include them.
In uGUI v0.3, the structure definition for a font is:

typedef struct { unsigned char* p; UG_S16 char_width; UG_S16 char_height; } UG_FONT;

But ttf2ugui creates a structure definition with the following format:
const UG_FONT font_NAME_SIZE = { (unsigned char*)pointer_to_font, FONT_TYPE_1BPP, charWidth, charHeight, startChar, endChar, Name };

Did you modify ugui to use the extra parameters or do I have the wrong version?

Many thanks.

I've compiled it for windows, it might be a good idea to add it, not everybody knows how to setup a cygwin envirnment, also it's time-consuming.

The utility runs on Mac (surprise!), but one needs to install freetype:

brew install freetype

When running, use the full path to the font ttf, e.g.:
./ttf2ugui --font /System/Library/Fonts/Supplemental/Arial.ttf --dpi 140 --size 14 --dump

uint8_t b = bits[(i*bpp_mul+i_idx) * face->glyph->bitmap.pitch + ((j*bpp_mul+j_idx) / 8)];
The logic is hard to understand. i_idx, j_idx is possible in the range [0, 16), the first part i_idx* pitch, the second part j_idx/8 ， I feel it is strange.

Is it possible to explain the meaning of the code? I feel it tries to change the pixel pitch from 16bit to 8bit bpp. the i_idx, j_idx is [0, 16) loop, the b value got from the buffer is not understandable.

Dear AriZuu,
you've done a great job in this project; I 've just wanted to ask you how to make this project work for Arabic or Persian fonts?
