Format Overview
PNG (.png) is a lossless raster image format supporting truecolor, palette, interlacing, and alpha transparency. Use sample .png files to test decoder compliance, color profile handling, and transparency rendering.
Validation Methodology
- Validate MIME sniffing against extension and file signatures.
- Test transparency, color profile, and resize pipelines.
- Benchmark decode speed and memory use for larger dimensions.
