The extra 100 characters are the hidden ones that the ZOG uses to track your whereabouts and alert the JIDF to your choice of breakfast cereals.

No, really, what's going on?

The bump limit on /vg/ was suddenly changed to 750 as well without notice.
moot writes news post after news post, but I don't feel informed at all.

Beats me, man. Not every company decision needs to be explained. Some things we just have no right to ever know.

>>267946 (OP)
Protip: The maximum length is actually 2000. 1500 is just an estimate owing to the fact that some character must be expanded into an HTML encoded equivalent.

Source on it changing, by the way?

I have made 1500 character posts before, and now a post would only pass through after cutting it down to exactly 1400 chacters.

4chanX did the counting.

Dunno what board you're on. I can still post up to the true 2000 character limit.

"Chunks" within the file

After the header comes a series of chunks, each of which conveys certain information about the image. Chunks declare themselves as critical or ancillary, and a program encountering an ancillary chunk that it does not understand can safely ignore it. This chunk-based storage layer structure, similar in concept to a container format, is designed to allow the PNG format to be extended while maintaining compatibility with older versions-it provides forward compatibility, and this same file structure (with different signature and chunks) is used in the associated MNG, JNG, and APNG formats.

A chunk consists of four parts: length (4 bytes), chunk type/name (4 bytes), chunk data (length bytes) and CRC (cyclic redundancy code/checksum; 4 bytes). The CRC is a network-byte-order CRC-32 computed over the chunk type and chunk.

Chunks are given a four letter case sensitive ASCII type/name; compare FourCC. The case of the different letters in the name (bit 5 of the numeric value of the character) is a bit field that provides the decoder with some information on the nature of chunks it does not recognize.

The case of the first letter indicates if the chunk is critical or not. If the first letter is uppercase, the chunk is critical; if not, the chunk is ancillary. Critical chunks contain information that is necessary to read the file. If a decoder encounters a critical chunk it does not recognize, it must abort reading the file or supply the user with an appropriate warning.

4chan X counted over 1600 characters for this.
