Return a fresh PNG buffer given a set of PNG chunks
npm install png-chunks-encode
Return a fresh PNG buffer given a set of PNG chunks. Useful in combination with png-chunks-encode to easily modify or add to the data of a PNG file.
By adding your own tEXt or zEXt chunks you have a useful alternative to LSB steganography for making "magical" images with "secret" data available for your applications: the data is hardly hidden this way, but you can store as much as you like. If you really wanted to, you could probably get away with sneaking a 300MB 3D model in there without too much trouble 👻
Takes an array of chunks, each with a name and data:
`` javascript`
[
{ name: 'IHDR', data: Uint8Array([...]) },
{ name: 'IDAT', data: Uint8Array([...]) },
{ name: 'IDAT', data: Uint8Array([...]) },
{ name: 'IDAT', data: Uint8Array([...]) },
{ name: 'IDAT', data: Uint8Array([...]) },
{ name: 'IEND', data: Uint8Array([]) }
]
And returns a Uint8Array` containing the raw PNG buffer.
