Reference

Just a quick refresher on different features.

Resampling

Always use Lanczos 3 (non-separable) for the best quality. Processing speed is irrelevant.

• Nearest Neighbor — Simple resampling which has the fastest processing time. Use for hard-edge images.
• Bilinear — Algorithmic resampling for use when shrinking images.
• Bicubic — Algorithmic resampling for use when enlarging images. Resampling is smoother than bilinear but has a slower processing time.
• Lanczos 3 (separable) — Complex algorithmic resampling which gives the best results but with the longest processing time.
• Lanczos 3 (non-separable) — The best results, but slightly slower than separable.
