Function Documentation

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

Encode the symbol using the frequency and lookup table supplied by cpr. Parameters: cpr  Pointer to an initialsed, populated and processed compression structure ctx  Context, pointer to the arithmetic encoder context sym  Symbol to compress 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(cpr)

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

Increment the bin of the histogram corresponding to val. 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(cpr)
