|| DESCRIPTION: ||
|
|
|| ------------ ||
|
|
|| ||
|
|
|| This file defines a tagtree procedure used to encode/decode two types of ||
|
|
|| information found defining in a codeblock in specific quality layer: ||
|
|
|| ||
|
|
|| - The inclusion tag records if a codeblock has any contribution ||
|
|
|| to a quality layer. ||
|
|
|| - The number of leading bitplanes that are not significant/only ||
|
|
|| populated by zero bits. ||
|
|
|| ||
|
|
|| For more information on the encoding/decoding process please refere to JPEG2000 ||
|
|
|| by D. S. Taubman and M. W. Marcellin (p. 384). ||
