Image Font

Render images as glyphs inside labels, useful for emoji and icon sets.

Image glyphs inside label text

Replace private-use code points with PNG images rendered by lv_imgfont.

lv_imgfont_create builds an 80 px image font whose path callback returns an embedded emoji_F617 image for U+F617 and a file path for U+F600 (prefixed with "A:" unless LV_USE_FFMPEG is enabled). The font's fallback is set to LV_FONT_DEFAULT so ASCII characters fall through. A centered label renders "12\uF600\uF617AB", mixing the two emoji images with normal text.
