デモ・サンプル

JPEG 2000 JPIP Web デモ

This Windows and Java demonstration allows a user to select a region of interest within a compressed JPEG 2000 image residing on a Pegasus server. The selected region of interest is progressively transmitted and decompressed at the client workstation. The user can control the region of interest selected and view the image bit rate transfer and decompression.

Best viewed with Internet Explorer 6 or higher.

Apollo 圧縮デモ

This Windows application allows you to read a variety of image formats including Bitmap, JPEG, JPEG 2000, JPEG XR, Lossless JPEG, JPEG-LS, RAW and Camera RAW images. Apollo users can configure compression options to immediately see the results including compression ratio, compression speed and expansion speed. Want to know how fast or how small PICTools can compress your images? Stop wondering, download Apollo today and see for yourself.
