Pixel Art Scaler

Deterministic algorithms for upscaling pixel art that preserve aesthetics by adding valid sub-pixels through edge detection and pattern matching.

When to Use

✅ Use for:

• Upscaling retro game sprites, icons, and pixel art
• 2x, 3x, 4x scaling with edge-aware interpolation
• Preserving sharp pixel art aesthetic at higher resolutions
• Converting 8x8, 16x16, 32x32, 48x48 pixel art for retina displays
• Comparing deterministic vs AI/ML approaches

❌ NOT for:

• Photographs or realistic images (use AI super-resolution)
• Simple geometric scaling (use nearest-neighbor)
• Vector art (use SVG)
• Text rendering (use font hinting)
• Arbitrary non-integer scaling (algorithms work best at 2x, 3x, 4x)
