JPEG 2000 (JP2)
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 save the image to a JP2 file, you can choose to view download progression by resolution, quality, and position.

The File
 Import command lets you place the file as an object in the active image. If you want to open the file as an image, click File Open. |

(Windows Vista) Choose JP2 – JPEG 2000 Bitmaps (*.jp2; *.j2k) from the list box next to the File name box.

ResolutionQuality — lets you set the image download from low to high resolution so that the size of the entire image increases
|

•
|
ResolutionPosition — lets you set the image download from the upper-left corner of the image to the lower-right corner

Setting a progression by image quality lets a user with a “slow” network connection stop downloading a file when the desired quality is reached.
