Kakadu Demo loads

What people are saying about Kakadu software:

Hello David (Taubman)
Thanks a lot for the help, I will try to implement this immediately.

Thanks
Sylvain

Thanks for that David,
I'll certainly look into doing as you've suggested - at least when
deadlines are a little less pressing

Hi David,
Thanks for the "-record" suggestion. It helped me figure out what the problem was. I was supplying incorrect parameters...

regards,
Rajan

Professor Taubman,
Thank you. After following your suggestion, I was able to successfully compile under Mac OS X all 14 of the Kakadu bin/Darwin-gcc executables.In my initial tests on a dual processor G5, I am getting a speed up of about 1.75 times... I consider this to be an excellent speed up.

Thank you for advancing JPEG2000 technology.
Greg

Kakadu SDK demonstration loads

Kakadu is a complete implementation of the JPEG2000 standard, Part 1, -- i.e., ISO/IEC 15444-1.

JPEG2000 Interactive Image Browsing with Kakadu Installation steps:

Install the "kdu_show" application v4.2 or later on your Windows platform.

Run "kdu_show" at least once -- it will register the "jpip:" protocol name for you so that "kdu_show" is automatically launched from iExplorer when you try the links below.

Try out the following links, using iExplorer. Alternatively, you can open kdu_show and use the File Open URL dialog to enter the URL s embedded in the links below.

JPIP Interactive Browsing Links:
(NB: if these don t work, I might need to restart the server on the old windows box I use to serve them e.g., after a power failure. You can always run your own copy of the client/server tools in your local environment to test it all out).

Note the metadata labels for each image (hold the control key down while moving the mouse) You need v4.3 or later to properly browse this composit image.

Helpful Notes:

If you had trouble using these links with kdu_show versions prior to v4.1, the problem may well have been fixed there was an unfortunate bug in the way the windows registry was initialized when you loaded the kdu_show application for the first time which resulted in the use of an invalid transport protocol, unless explicitly selected otherwise.

Details of the protocol used to communicate with the server depend upon configuration parameters, which can only be edited by opening the URL entry dialog box, which may be found via the File Open URL menu item, or by using the "u" acelerator key in "kdu_show".

In particular, you may wish to configure a cache directory, and you may wish to see whether your networking environment allows you to use the "http-tcp" session-type, rather than just "http". The former is more efficient for both the server and the client. The server is deliberately configured to deliver at most 4 kBytes per second to any one client, although the "kdu_server" application is certainly capable of much higher data rates.

The "kdu_show" application initially displays the image at a resolution which it deems to be suitable. Many of the links below refer to quite large images, so make sure you use the zoom capability ("z" accelerator) to see the higher resolution details.

By default, the spatial region of interest is the full window size (try panning around a zoomed image), but you can draw a focus box with the mouse, which is much smaller than the window itself. Try using the shift-s, shift-w and shift-arrow accelerators to move and resize the focus box as fast as you like, rather than being hamstrung by lack of mouse dexterity.

Also try dragging the mouse while the shft key and left mouse button are depressed, for an alternate panning approach.

Although "kdu_show" will initially come up with its status bar set to display download statistics, you may like to use the "t" accelerator to view other status information of interest.
