Tiny TTF font engine

Usage

Allow using TrueType fonts LVGL. Based on https://github.com/nothings/stb

When enabled in lv_conf.h with LV_USE_TINY_TTF lv_tiny_ttf_create_data(data, data_size, line_height) can be used to create a TTF font instance at the specified line height. You can then use that font anywhere lv_font_t is accepted.

By default, the TTF or OTF file must be embedded as an array, either in a header, or loaded into RAM in order to function.

However, if LV_TINY_TTF_FILE_SUPPORT is enabled, lv_tiny_ttf_create_file(path, line_height) will also be available, allowing tiny_ttf to stream from a file. The file must remain open the entire time the font is being used.

After a font is created, you can change the size by using lv_tiny_ttf_set_size(font, line_height).
