Changing character size in Lcd.draw_number() Arduino

I’ve been playing with the Arduino IDE and the rephone and I was wondering if there was a way to change character size, font or anything else (bold, italic, etc). I haven’t found anything looking through the .h file so I was wondering if there was something I missed, or if I’d have to try implementing it on my own.

Thanks for the help.

These is a api “vm_graphic_set_font_size()” in file " …\Arduino_IDE_for_RePhone\hardware\arduino\mtk\system\libmtk\include\vmgraphic_font.h "
can change font size. You can check it in file"…\Arduino_IDE_for_RePhone\hardware\arduino\mtk\libraries\LDisplay\utility\Display.cpp" on line 141 and 194.
