Function Documentation

void LSEC_compress (  LSEC_compression *  cpr, void *  ctx, unsigned  sym )  [inline, static]

Encode a symbol using the frequency and lookup table supplied by a compression. This function does not return errors since propogation of those errors to a point in LSEC where reasonable decisions about error handling can be made is problematic. Instead, errors are latched and can be checked using LSEC_checkCompression. Parameters: cpr  Pointer to an initialsed, populated and processed compression structure ctx  Context, pointer to the arithmetic encoder context sym  Symbol to compress

void LSEC_histogram (  LSEC_compression *  cpr, unsigned  sym )  [inline, static]

Increment the bin of the histogram corresponding. Parameters: cpr  Pointer to an allocated, initialised, compression structure sym  Symbol to add to the histogram This function does not return errors since propogation of those errors to a point in LSEC where reasonable decisions about error handling can be made is problematic. Instead, errors are latched and can be checked using LSEC_checkCompression.
