png-chunks-extract
Extract the data chunks from a PNG file.
Useful for reading the metadata of a PNG image, or as the base of a more complete PNG parser.
Usage
chunks = extract(data)
Takes the raw image file data as a Uint8Array or Node.js Buffer, and returns an array of chunks. Each chunk has a name and data buffer:
[
{ name: 'IHDR', data: Uint8Array([...]) },
{ name: 'IDAT', data: Uint8Array([...]) },
{ name: 'IDAT', data: Uint8Array([...]) },
{ name: 'IDAT', data: Uint8Array([...]) },
{ name: 'IDAT', data: Uint8Array([...]) },
{ name: 'IEND', data: Uint8Array([]) }
]
