Sobre los archivos PBMComparativa de ventajas
GIF Ventajas
- Universal animation support — every browser, every chat app, every social network.
- Transparent backgrounds for compositing against any page color.
- Lossless for its limited palette — pixel-perfect at 256 colors.
- Self-contained: no codec, no browser plugin, no third-party player needed.
PBM Ventajas
- Extreme simplicity — a 20-line parser handles every PBM.
- Ideal as pipeline intermediate format.
- Plain ASCII variant is human-readable and diff-able.
- 37+ years of unchanged stability.
Limitaciones
GIF Limitaciones
- Limited to 256 colors per frame — looks posterized on photographs.
- Dithering for color-rich images makes files huge (often 10× an MP4 equivalent).
- No audio track.
- Transparency is 1-bit (on/off) — no smooth alpha blending.
- Poor compression compared to modern formats (WebP, MP4, AVIF).
PBM Limitaciones
- No compression — files are huge compared to PNG or JPEG.
- No color profile, no metadata, no transparency.
- Not a delivery format — strictly for pipelines.
- ASCII variant is 8× larger than binary for the same image.
