The next livestream will be on comparing the file formats of PNG, GIF and PCX, all lossless image formats and global standards [during their lifetime]:

we can focus on the different design decisions and their impact on engineering, parsing & security.

Today, I'll stream about the PCX format.

While it is an outdated and irrelevant format nowadays, its structure and lack of forward-thinking makes it very interesting from a file format design perspective.

Data chunked that way doesn’t have a pre-declared length.

The total length is obtained by adding all the lengths of each block.

Do you know any format or protocol that uses chunking besides Gif/Jif?

ICYDK chunking is slicing data in blocks smaller than 256 bytes, with the length before each block. A null block terminates the sequence.
