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.
oint 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.

oint 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.

ofloat 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.

o IWEncoderParms(void)
Constructor. Initializes the structure with the default values.
