Detailed Description

IW44 encoding parameters.

This data structure gathers the quality specification parameters needed for encoding each chunk of an IW44 file. Chunk data is generated until meeting either the slice target, the size target or the decibel target.

Member Data Documentation

int IWEncoderParms::bytes

Size target.

Data generation for the current chunk stops if the total data size (in this chunk and all the previous chunks), expressed in bytes, reaches value size#. The default value #0# has a special meaning: data will be generated regardless of the file size.

Definition at line 202 of file IW44Image.h.

float IWEncoderParms::decibels

Decibel target.

Data generation for the current chunk stops if the estimated luminance error, expressed in decibels, reaches value decibel#. The default value #0# has a special meaning: data will be generated regardless of the estimated luminance error. Specifying value #0# in fact shortcuts the computation of the estimated luminance error and sensibly speeds up the encoding process.

Definition at line 209 of file IW44Image.h.

int IWEncoderParms::slices

Slice target.

Data generation for the current chunk stops if the total number of slices (in this chunk and all the previous chunks) reaches value slice#. The default value #0# has a special meaning: data will be generated regardless of the number of slices in the file.
