PNG package reference

BinaryParsec.Protocols.Png exposes zero-copy chunk tokenizers and a validated file-level parser.

What this shows

The PNG package keeps the signature, chunk envelope, chunk stream, and owned file model separate. That makes the binary structure visible while still giving callers a clean file-level entry point.

Core shape

• Png
• PngChunkEnvelope
• PngSlice
• PngChunkStream
• PngImageHeader
• PngChunk
• PngFile

What you can do

• Match the PNG signature and read the first chunk without copying.
• Walk chunk envelopes through IEND.
• Materialize a validated PNG file model from a contiguous datastream.
