/**
* A subclass of ImageWriteParam for writing images in
* the JPEG 2000 format.
*
* JPEG 2000 plugin supports to losslessly or lossy compress gray-scale,
* RGB, and RGBA images with byte, unsigned short or short data type. It also
* supports losslessly compress bilevel, and 8-bit indexed. The result data
* is in the format of JP2 (JPEG 2000 Part 1 or baseline format).
*
*
Many encoding parameters for JPEG 2000 can be tile-component specific.
* These parameters are marked as Yes in the column
* TC_SPEC in the following parameter table.
* They must be provided according to the pattern:
* [<tile-component idx>] <param> (repeated as many time as needed),
* where <tile-component idx> respect the following policy according to
* the degree of priority:
*
* (1) t<idx> c<idx> : Tile-component specification. (2) t<idx> : Tile specification. (3) c<idx> : Component specification. (4) <void> : Default specification.
* Where the priorities of the specifications are:
* (1) > (2) > (3) > (4), (">" means "overrides")
* <idx>: "," separates indexes, "-" separates bounds of indexes list.
* (for example, 0,2-4 means indexes 0,2,3 and 4).
*
*
The parameters for encoding JPEG 2000 are listed in the following table:
*
* *
* JPEG 2000 Plugin Decoding Parameters
* Parameter Name Description TC_SPEC
* encodingRate
* The bitrate in bits-per-pixel for encoding. Should be set when
* lossy compression scheme is used. With the default value
* Double.MAX_VALUE, a lossless compression will be done.
*
* No
*
*
* lossless
* Indicates using the loseless scheme or not. It is equivalent to
* use reversible quantization and 5x3 integer wavelet filters. The
* default is true.
*
* No
*
*
* componentTransformation
* Specifies to utilize the component transformation on some tiles.
* If the wavelet transform is reversible (w5x3 filter), the Reversible
* Component Transformation (RCT) is applied. If not reversible
* (w9x7 filter), the Irreversible Component Transformation (ICT) is used.
*
* Yes, Tile_Specific
*
*
* filters
* Specifies which wavelet filters to use for the specified
* tile-components. JPEG 2000 part I only supports w5x3 and w9x7 filters.
*
* Yes
*
*
* decompositionLevel
* Specifies the wavelet decomposition levels to apply to
* the image. If it is 0, no wavelet transform is performed, in which
* case the original image data will be sent to the encoder and an example
* is the binary data. All components and all tiles have the same number
* of decomposition levels. The default value is 5.
*
* No
*
*
* guardBits
* The number of bits used for each tile-component in the quantizer
* to avoid overflow. It takes values in the range 0 through 7. The
* default value is 2.
*
* Yes
*
*
* quantizationStep
* This parameter specifies the base normalized quantization step
* size for the tiles/components. It is normalized to a dynamic range
* of 1 in the image domain. This parameter is ignored in reversible
* coding. The default value is 0.0078125.
*
* Yes
*
*
* quantizationType
* Specifies which quantization type to use for specified
* tiles/components. Not specified for lossless compression. By default,
* the quantization step size is "expounded". Supported quantization
* types specification are : "reversible" (no quantization), "derived"
* (derived quantization step size) and "expounded".
*
* Yes
*
*
* codeBlockSize
* Specifies the maximum code-block size to use for tile-component.
* The maximum width and height is 1024, however the block size
* (i.e. width x height) must not exceed 4096. The minimum width and
* height is 4. The default values are (64, 64).
*
* Yes
*
*
* progressionType
* Specifies which type of progression should be used when generating
* the codestream.
* The format is [<tile index>]
* res|layer|res-pos|pos-comp|comp-pos [res_start comp_start layer_end
* res_end comp_end prog] [[res_start comp_start layer_end res_end
* comp_end prog]...] [[<tile-component idx]...].
*
The value "res" generates a resolution progressive
* codestream with the number of layers specified by "layers" parameter.
* The value "layer" generates a layer progressive codestream with
* multiple layers. In any case, the rate-allocation algorithm optimizes
* for best quality in each layer. The quality measure is mean squared
* error (MSE) or a weighted version of it (WMSE). If no progression
* type is specified or imposed by other parameters, the default value
* is "layer". It is also possible to describe progression order
* changes. In this case, "res_start" is the index (from 0) of the
* first resolution level, "comp_start" is the index (from 0) of the
* first component, "layer_end" is the index (from 0) of the first layer
* not included, "res_end" is the index (from 0) of the first
* resolution level not included, "comp_end" is index (from 0) of
* the first component not included and "prog" is the progression type
* to be used for the rest of the tile/image. Several progression
* order changes can be specified, one after the other.
*
* Yes
*
*
* packPacketHeaderInTile
* Indicates that the packet headers are packed in the tiles' headers.
* The default is false.
*
* No
*
*
* packPacketHeaderInMain
* Indicates that the packet headers are packed in the main header.
* The default is false.
*
* No
*
*
* packetPerTilePart
* Specifies the maximum number of packets to be put into one tile-part.
* Zero means putting all packets in the first tile-part of each tile.
*
* No
*
*
* ROIs
* Specifies ROIs shape and location. The component index specifies
* which components contain the ROI. If this parameter is used, the
* codestream is layer progressive by default unless it is overridden by
* the progressionType. A rectanglar or circular ROI can be
* specified in the format: [<component idx>] R <left>
* <top> <width> <height> or [<component idx>] C
* <center x> <center y> <radius>. An arbitrary shape
* can be assigned by [<component idx>] A <PGM file>
*
* Yes, component-specified
*
*
* startLevelROI
* This parameter defines the lowest resolution levels to belong to
* the ROI. By doing this, it is possible to avoid getting
* information for the ROI at an early stage of transmission.
* startLevelROI = 0 means the lowest resolution level belongs to
* the ROI, 1 means the second lowest etc. The default values, -1,
* deactivates this parameter.
*
* No
*
*
* alignROI
* By specifying this parameter, the ROI mask will be limited to
* covering only entire code-blocks. The ROI coding can then be
* performed without any actual scaling of the coefficients but by
* instead scaling the distortion estimates.
*
* No
*
*
* bypass
* Uses the lazy coding mode with the entropy coder. This will bypass
* the MQ coder for some of the coding passes, where the distribution
* is often close to uniform. Since the MQ codeword will be terminated
* at least once per lazy pass, it is important to use an efficient
* termination algorithm, methodForMQTermination.
* true enables, and false disables it. The default value is false.
*
* Yes
*
*
* resetMQ
* If this is enabled the probability estimates of the MQ coder are
* reset after each arithmetically coded (i.e. non-lazy) coding pass.
* true enables, and false disables it. The default value is false.
*
* Yes
*
*
* terminateOnByte
* If this is enabled the codeword (raw or MQ) is terminated on a byte
* boundary after each coding pass. In this case it is important to use
* an efficient termination algorithm, "methodForMQTermination".
* true enables, and false disables it. The default value is false.
*
* Yes
*
*
* causalCXInfo
* Uses vertically stripe causal context formation. If this is
* enabled the context formation process in one stripe is independant of
* the next stripe (i.e. the one below it). true enables, and false
* disables it. The default value is false.
*
* Yes
*
*
* codeSegSymbol
* Inserts an error resilience segmentation symbol in the MQ codeword
* at the end of each bit-plane (cleanup pass). Decoders can use this
* information to detect and conceal errors. true enables, and false
* disables it. The default value is false.
*
* Yes
*
*
* methodForMQTermination
* Specifies the algorithm used to terminate the MQ codeword. The
* most efficient one is "near_opt", which delivers a codeword which
* in almost all cases is the shortest possible. The "easy" is a
* simpler algorithm that delivers a codeword length that is close
* to the previous one (in average 1 bit longer). The "predict" is
* almost the same as the "easy" but it leaves error resilient
* information on the spare least significant bits (in average 3.5 bits),
* which can be used by a decoder to detect errors. The "full" algorithm
* performs a full flush of the MQ coder and is highly inefficient. It
* is important to use a good termination policy since the MQ codeword
* can be terminated quite often, specially if the "bypass" or
* "terminateOnByte" parameters are enabled (in the normal case it would
* be terminated once per code-block, while "terminateOnByte" is specified
* it will be done almost 3 times per bit-plane in each code-block).
* The default value is "near_opt".
*
* Yes
*
*
* methodForMQLengthCalc
* Specifies the algorithm to use in calculating the necessary MQ
* length for each decoding pass. The best one is "near_opt", which
* performs a rather sophisticated calculation and provides the best
* results. The "lazy_good" and "lazy" are very simple algorithms
* that provide rather conservative results. "lazy_good" performs
* slightly better. Please use the default unless the experiments
* show the benefits of different length calculation algorithms.
* The default value is "near_opt".
*
* Yes
*
*
* precinctPartition
* Specifies precinct partition dimensions for tiles/components. They
* are stored from those applied to the highest resolution to those
* applied to the remaining resolutions in decreasing order. If less
* values than the number of decomposition levels are specified, then
* the last two values are used for the remaining resolutions.
*
* Yes
*
*
* layers
* Explicitly specifies the codestream layer formation parameters.
* The rate (double) parameter specifies the bitrate to which the first
* layer should be optimized. The layers (int) parameter, if present,
* specifies the number of extra layers that should be added for
* scalability. These extra layers are not optimized. Any extra rate
* and layers parameters add more layers, in the same way. An
* additional layer is always added at the end, which is optimized
* to the overall target bitrate of the bit stream. Any layers
* (optimized or not) whose target bitrate is higher that the overall
* target bitrate are silently ignored. The bitrates of the extra layers
* that are added through the layers parameter are approximately
* log-spaced between the other target bitrates. If several (rate, layers)
* constructs appear the rate parameters must appear in increasing order.
* The rate allocation algorithm ensures that all coded layers have a
* minimal reasonable size, if not these layers are silently ignored.
* Default: 0.015 +20 2.0 +10.
*
* No
*
*
* SOP
* Specifies whether start of packet (SOP) markers should be used.
* true enables, false disables it. The default value is false.
*
* Yes
*
*
* EPH
* Specifies whether end of packet header (EPH) markers should be used.
* true enables, false disables it. The default value is false.
*
* Yes
*
*
