Format Overview
HEIC (.heic) is a high-efficiency image format commonly used on mobile devices. Use sample HEIC files to test decoder support, conversion behavior, and metadata extraction pipelines.
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.
