비트맵 이모지

폰트 파일 내에 고정 해상도의 픽셀 기반 이미지로 저장되는 이모지.

Bitmap emoji store pre-rendered images at specific pixel dimensions. Common resolutions are 128×128, 96×96, and 64×64 pixels. When scaled beyond their native resolution, they become blurry.

Apple Color Emoji (sbix) and Google Noto Color Emoji (CBDT) both use bitmap approaches. Apple includes multiple resolutions per glyph to handle different display sizes, which is why the font file is over 100MB.

While bitmap emoji reproduce the intended design perfectly at their native size, the industry is gradually moving toward vector formats for better scalability and smaller file sizes.
