The chunks are sent out and received independently of one another. No knowledge of the data stream outside the currently-being-processed chunk is necessary for both the sender and the receiver at any given time. Each chunk is preceded by its size in bytes. The transmission ends when a zero-length chunk is received.
If an unordered chunk is fragmented, then each fragment has this flag set. B — If set, this marks the beginning fragment. An unfragmented chunk has this flag set. E — If set, this marks the end fragment. An unfragmented chunk has this flag set. Chunk length The chunk length has a minimum value of 21, as data of size less than one byte is ...
pngcrush is a free and open-source command-line utility for optimizing PNG image files. It reduces the size of the file losslessly – that is, the resulting "crushed" image will have the same quality as the source image.
A chunk is a fragment of information which is used in many multimedia file formats, such as PNG, IFF, MP3 and AVI. [1] Each chunk contains a header which indicates some parameters (e.g. the type of chunk, comments, size etc.). Following the header is a variable area containing data, which is decoded by the program from the parameters in the header.
The IDAT chunk contains the actual image data, which is the output stream of the compression algorithm. [19] IEND marks the image end; the data field of the IEND chunk has 0 bytes/is empty. [20] The PLTE chunk is essential for color type 3 (indexed color). It is optional for color types two and six (truecolor and truecolor with alpha) and it ...
A download manager manages files being downloaded from the internet. [1] Download managers break down files into multiple chunks for faster download speeds and allocate resources for downloading multiple items simultaneously. [2] Failed downloads can also be restarted from a download manager. [3]

variable-sized field: the chunk data itself, of the size given in the previous field. a pad byte, if the chunk's length is not even. Two chunk identifiers, "RIFF" and "LIST", introduce a chunk that can contain subchunks. The RIFF and LIST chunk data (appearing after the identifier and length) have the following format:
