Jpeg2000 Viewer Test
Jpeg2000 Viewer Test
 ActiveX Control for IE (plug-in, from Lura Tech) was downloaded;
 Some tiff files (about 100 to 150 megabytes each) were converted to
JPEG2000 format using LuraWave SmartCompress (free,
downloaded from Lura Tech website);
 the compression rate is 22:1, and the converted files range from 5 to 7
mega byte each;
 The converted JPEG2000 files were put online first in the “JPEG 2000
Test” section of the “help” page, and then were added to “browse” page as a
link below the thumbnail;
 This plug-in has very limited zoom function online, but it allows
users to save the file;
 Decide not to enable saving of JPEG2000 images due to the
copyright concerns.
