包路径：jj2000.j2k.quantization.QuantTypeSpec
类名称：QuantTypeSpec

QuantTypeSpec介绍

[英]This class extends ModuleSpec class in order to hold specifications about the quantization type to use in each tile-component. Supported quantization type are:

  • Reversible (no quantization)
  • Derived (the quantization step size is derived from the one of the LL-subband)
  • Expounded (the quantization step size of each subband is signalled in the codestream headers)
    [中]这个类扩展了ModuleSpec类，以便保存关于每个磁贴组件中使用的量化类型的规范。支持的量化类型包括：
    *可逆（无量子化）
    *派生（量化步长从LL子带之一派生）
    *（每个子带的量化步长在码流报头中用信号表示）
