[Zlib-devel] zlib ideas for 1.2.5 (fwd)

[Mark Adler]

Vincent,

This is the general topic of pre-processing filters.  zlib could provide such things.  They can be beneficial to compression such a what PNG does for images, XWRT does for XML and text, and what various pre-processors do for executable code.  I would consider providing a filter interface to zlib, and then others could provide add-on filters to zlib.

As for limits on values, that is automatically detected in building statistics on the data, and taken advantage of by the Huffman coding.
