- io.scif.jj2000.j2k.ModuleSpec
- - io.scif.jj2000.j2k.quantization.QuantTypeSpec

All Implemented Interfaces:

Cloneable
```
public class QuantTypeSpec
extends ModuleSpec
```
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)

  - QuantTypeSpec
```
public QuantTypeSpec(int nt,
                     int nc,
                     byte type)
```
    Constructs an empty 'QuantTypeSpec' with specified number of tile and components. This constructor is called by the decoder.
    
    Parameters:
    
    nt - Number of tiles
    
    nc - Number of components
    
    type - the type of the specification module i.e. tile specific, component specific or both.
  - QuantTypeSpec
```
public QuantTypeSpec(int nt,
                     int nc,
                     byte type,
                     J2KImageWriteParamJava wp,
                     String values)
```
    Constructs a new 'QuantTypeSpec' for the specified number of components and tiles and the arguments of "-Qtype" option. This constructor is called by the encoder.
    
    Parameters:
    
    nt - The number of tiles
    
    nc - The number of components
    
    type - the type of the specification module i.e. tile specific, component specific or both.

  - isDerived
```
public boolean isDerived(int t,
                         int c)
```
    Returns true if given tile-component uses derived quantization step size.
    
    Parameters:
    
    t - Tile index
    
    c - Component index
    
    Returns:
    
    True if derived quantization step size
  - isReversible
```
public boolean isReversible(int t,
                            int c)
```
    Check the reversibility of the given tile-component.
    
    Parameters:
    
    t - The index of the tile
    
    c - The index of the component
    
    Returns:
    
    Whether or not the tile-component is reversible
  - isFullyReversible
```
public boolean isFullyReversible()
```
    Check the reversibility of the whole image.
    
    Returns:
    
    Whether or not the whole image is reversible
  - isFullyNonReversible
```
public boolean isFullyNonReversible()
```
    Check the irreversibility of the whole image.
    
    Returns:
    
    Whether or not the whole image is reversible
