JPEG 2000 Standard Part II defines JPX file architecture rather than a specific, fixed set of data structures that will be found in a file. The ImageGear JPEG 2000 Component provides support for the following important JPX features, which extend the JPEG 2000 format features:
- The ability to read and write JPX format files.
- Much richer set of color specifications, compared to JPEG 2000. These include a much larger set of color spaces, arbitrary ICC profiles, and vendor-specific color spaces.
- ImageGear JPEG 2000 Component allows you to read JPX files with multiple compositing layers. ImageGear treats each compositing layer as a separate page within the JPX file.
- JPX file format extends JPEG 2000 with the ability to separate transparency channels into different code streams. In many image editing applications, the color data and the opacity data are edited separately, and thus it is useful to allow those channels to be stored in separate code streams.
- As soon as the JPEG 2000 Component is attached ImageGear Core, you can access the JPX Format Filter functionality using the Core API, in the same way as you would access functionality of other file format filters. Use the JPX filter control parameters to control the features that are specific to the JPX format. See IGControlParameter Object for information about how to work with the filter control parameters API. See JPX in the File Formats section for the list of control parameters available for JPX format.
