The JPEG 2000 (JP2) file format is a JPEG image with advanced compression and file data capabilities. JPEG 2000 standard files can store more descriptive file data (or metadata), such as dimensions, tone scale, color space, and intellectual property rights, than JPEG 2000 codestream files. Codestream files are optimized for network transmission since they resist bit errors that can cause data loss on low-bandwidth channels.
Not all Web browsers support JPEG 2000 formats. You may require a plug-in to view these files.
You can mask an area of a JP2 image to define a region of interest (ROI). If you apply a lower compression setting to the ROI, you can improve the image quality of the area.
When you export the image to a JP2 file, you can choose to view download progression by resolution, quality, and position.
