class lvfontio.OnDiskFont(file_path: str, max_glyphs: int = 100)

A font built into CircuitPython for use with LVGL

Create a OnDiskFont by loading an LVGL font file from the filesystem.

Parameters:

• file_path (str) – The path to the font file

• max_glyphs (int) – Maximum number of glyphs to cache at once

bitmap: displayio.Bitmap

Bitmap containing all font glyphs starting with ASCII and followed by unicode. This is useful for use with LVGL.

get_bounding_box() → Tuple[int, int]

Returns the maximum bounds of all glyphs in the font in a tuple of two values: width, height.
