Field Detail

progressionOrder

public int progressionOrder

Progression order used to save the file.

Valid values are:

• 0- LRCP Layer-Resolution-Component-Position
• 1- RLCP Resolution-Layer-Component-Position
• 2- RPCL Resolution-Position-Component-Layer
• 3- PCRL Position-Component-Resolution-Layer
• 4- CPRL Component-Position-Resolution-Layer

numLayers

public int numLayers

Number of bytes that the final codestream contains (it could vary a little for the LCTargetNumBytes).

Only positive values allowed.

multiComponentTransform

public int multiComponentTransform

Multiple component transformation. Allowed values are:

Valid values are:

• 0 - No multiple component transformation
• 1 - Component transformation used on components 0, 1, and 2
• 2 - Array-based
• 4 - DWT-based
• 3 - Array-based + DWT-based

WTLevels

public int[] WTLevels

DWT levels to apply for each component.

Negative values not allowed.

WTTypes

public int[] WTTypes

Discrete wavelet transform to be applied for each component.

Valid values are:

• 0 - Nothing
• 1 - Reversible 5/3 DWT
• 2 - Irreversible 9/7 DWT

MQCFlags

public boolean[] MQCFlags

Style of code-block coding passes. Definition in MQDecoder (see source code) Further information, see ISO/IEC 15444-1 section A.6.1 (table A-19).

blockHeights

public int[] blockHeights

Block height (exponent of 2) for each image component.

Values greater than 2.

blockWidths

public int[] blockWidths

Block width (exponent of 2) for each image component.

Values greater than 2.

precinctWidths

public int[][] precinctWidths

Precinct width in the transformed domain for each component and resolution level. Index means [z][rLevel] (rLevel==0 is the LL subband, and 1, 2, ... represents next starting with the little one).

Values equal or greater than BlockWidth.

precinctHeights

public int[][] precinctHeights

Same as resolutionPrecinctWidths but for precinct heights.

Values equal or greater than blockHeight.

useSOP

public boolean useSOP

Use of start and end of packet headers.

In both cases true indicates that the marker is used.

useEPH

public boolean useEPH
