CSJ2K.Color Namespace

Classes

ChannelDefinitionMapper

This class is responsible for the mapping between requested components and image channels.

This class analyzes the image to provide colorspace information for the decoding chain. It does this by examining the box structure of the JP2 image. It also provides access to the parameter list information, which is stored as a public final field.

ColorSpaceException

This exception is thrown when the content of an image contains an incorrect colorspace box

ColorSpaceMapper

This is the base class for all modules in the colorspace and icc profiling steps of the decoding chain. It is responsible for the allocation and iniitialization of all working storage. It provides several utilities which are of generic use in preparing DataBlks for use and provides default implementations for the getCompData and getInternCompData methods.

ColorSpaceMapper.ComputedComponents

EnumeratedColorSpaceMapper

This class provides Enumerated ColorSpace API for the jj2000.j2k imaging chain by implementing the BlkImgDataSrc interface, in particular the getCompData and getInternCompData methods.

EsRgbColorSpaceMapper

This decodes maps which are defined in the e-sRGB colorspace into the sRGB colorspace.

PalettizedColorSpaceMapper

This class provides decoding of images with palettized colorspaces. Here each sample in the input is treated as an index into a color palette of triplet sRGB output values.

Resampler

This class resamples the components of an image so that all have the same number of samples. The current implementation only handles the case of 2:1 upsampling.

SYccColorSpaceMapper

This decodes maps which are defined in the sYCC colorspace into the sRGB colorspadce.
