Field Detail

inClassIdentifier

public long inClassIdentifier

It is a unique identifer.

JPIPMessageHeader.inClassIdentifier

isCodingPassesInfo

public boolean isCodingPassesInfo

Indicates

filePointers

public long[] filePointers

Contains the position for each image packet in the image file.

This attribute is only available when the isCodingPassesInfo attribute is false

lengths

public long[] lengths

Contains the length for each image packet in the image file.

This attribute is only available when the isCodingPassesInfo attribute is false

filePointersCodingPasses

public long[][][][] filePointersCodingPasses

Contains a file pointer for each coding pass in the image file. Indexes means:
subband yBlock xBlock coding pass

This attribute is only available when the isCodingPassesInfo attribute is true

lengthsCodingPasses

public int[][][][] lengthsCodingPasses

Contains the length of each coding pass belonging to the precinct. Indexes are the same as in filePointersCodingPasses.

This attribute is only available when the isCodingPassesInfo attribute is true

zeroBitPlanes

public int[][][] zeroBitPlanes

Number of zero bit planes for each block in a precinct-subband. Each entry maps the precinct identifier with a three-dimensional array with the zero bit planes for each subband-block in the precinct. Indexes of the three-dimensional array mean: subband: 0 - HL, 1 - LH, 2 - HH (ifresolutionLevel == 0 --> 0 - LL)
yBlock: block row in the subband
xBlock: block column in the subband

Only positive values allowed (0 value is possible too. If 0 --> block has not empty/0 bit planes).

firstLayer

public int[][][] firstLayer

First layer in which the block is included. Indices means:
subband: 0 - HL, 1 - LH, 2 - HH (ifresolutionLevel == 0 --> 0 - LL)
yBlock: block row in the subband
xBlock: block column in the subband

Only positive values allowed (0 value is possible too. If 0 --> block is included in first quality layer).
