these conditions: (1) If any part of the source code for this software is distributed, then this README file must be included, with this copyright and no-warranty notice unaltered; and
any additions, deletions, or changes to the original files must be clearly indicated in accompanying documentation. (2) If only executable code is distributed, then the accompanying
documentation must state that “this software is based in part on the work of the Independent JPEG Group”. (3) Permission for use of this software is granted only if the user accepts full
responsibility for any undesirable consequences; the authors accept NO LIABILITY for damages of any kind. ansi2knr.c is included in this distribution by permission of L. Peter Deutsch,
sole proprietor of its copyright holder, Aladdin Enterprises of Menlo Park, CA. ansi2knr.c is NOT covered by the above copyright and conditions, but instead by the usual distribution
terms of the Free Software Foundation; principally, that you must include source code if you redistribute it. (See the file ansi2knr.c for full details.) However, since ansi2knr.c is not
needed as part of any program generated from the IJG code, this does not limit you more than the foregoing paragraphs do. The Unix configuration script “configure” was produced with
GNU Autoconf. It is copyright by the Free Software Foundation but is freely distributable. The same holds for its supporting scripts (config.guess, config.sub, ltconfig, ltmain.sh).
Another support script, install-sh, is copyright by M.I.T. but is also freely distributable. It appears that the arithmetic coding option of the JPEG spec is covered by patents owned by IBM,
AT&T, and Mitsubishi. Hence arithmetic coding cannot legally be used without obtaining one or more licenses. For this reason, support for arithmetic coding has been removed from
the free JPEG software. (Since arithmetic coding provides only a marginal gain over the unpatented
Huffman mode, it is unlikely that very many implementations will support it.) So far as we are aware, there are no patent restrictions on the remaining code. The IJG distribution
formerly included code to read and write GIF files. To avoid entanglement with the Unisys LZW patent, GIF reading support has been removed altogether, and the GIF writer has been
simplified to produce “uncompressed GIFs”. This technique does not use the LZW algorithm; the resulting GIF files are larger than usual, but are readable by all standard GIF decoders.

What is Autodesk®StitcherTM?
Using Autodesk Stitcher, you can build high-quality panoramas for the Web, film, print, and 3D animations.
With advanced features, such as the automatic stitching engine, automatic color-matching, and real-time
previewing, Stitcher gives photographers and artists the power to deliver the most impressive panoramas in all
the popular formats. Stitcher quickly creates wide-angle, high-resolution 360° × 180° panoramic images from
horizontally and vertically overlapping photos. You can create new image sets from the panorama using a
virtual camera that is equipped with zoom, pan, and roll motion. Your panorama can be rendered as a cube,
plane, cylinder, spherical projection, and in QuickTime®(Cylindrical QTVR and Cubic QTVR), VRML,
ImmerVision®Pure Player, Java, and HTML (version dependent). This means that you can create panoramic
images for definition mattes, environment maps, 3D models, high-impact Web pages including publishing in
GoogleTMEarth.
Images that are loaded into Stitcher are displayed as thumbail images. You can drag
thumbnail images into the work area and stitch them manually, or, using the default
workflow, Stitcher automatically stitches the loaded images together and then displays
them in the display area.
If the automatic process fails you can do semi-automatic stitching by placing the
images in an overlapping position to match features in each of the images.
Stitcher calibrates the camera focal length and distortion parameters from original
images. No information is required about the camera or the scale of the scene.
However, an approximate value for the camera’s focal length improves the panorama.
Results are accurate to within one pixel.
Stitcher automatically blends colors along the edges of each image to provide color
consistency throughout your panorama. In addition, the application wraps each image
to exactly match all adjacent images and to remove distortion. These processes are
rapid with precise, high-quality results.
Your high-quality panoramas can then be quickly produced and rendered to various
formats (such as QuickTime VR) for web viewing or to animation software format for
use as matte paintings (which can be used as backgrounds), or occlusions. Entire
panoramas can also be environment mapped onto animated objects. You can use the

resulting panoramas to create new image sets by filming in the image using a virtual
camera.

Autodesk Stand-Alone Licensing
This guide provides information and instructions for managing an Autodesk stand-
alone license on a single-user workstation.
A stand-alone license allows you to run Stitcher on a single workstation. To obtain a
license, you register your product.
You can use Stitcher in trial mode for a given number of days from the first time you
launch the product. The number of days that a trial mode is active differs between
Autodesk products. You can register your license at any time before the trial period
expires. After the trial period expires, you cannot run Stitcher until you register the
product.
When you register Stitcher, you receive an activation code. If you register online, your
activation code is automatically retrieved from Autodesk and Stitcher starts. If you
register offline, you request an activation code from Autodesk. Upon receipt, you
manually enter the activation code in the Product Activation wizard. The Product
Activation wizard is displayed every time you launch a product that has not been
registered.
NOTE If you are installing and using Stitcher on both operating systems of a dual-boot
operating system, you must obtain a separate activation code for each operating system.
The license file stays on your workstation when you uninstall Stitcher. If you reinstall
Stitcher on the same workstation, the license information is still valid. You do not have
to reactivate Stitcher.

Update Your Serial Number
If you installed Stitcher with the trial serial number (000-00000000), you should update
that trial serial number with a valid serial number. Your valid serial number is located
in the Autodesk Upgrade and Licensing Information email you received when you
purchased or upgraded Stitcher online.
When you register and activate Stitcher, you are asked for the product serial number, which
gets automatically updated upon completion of the activation process.
If you have a multi-product bundle of software that uses a single serial number, only
the first product you register and activate displays the updated serial number. For other
products to display the serial number, you need to update them from the Help menu.
NOTE In order for the updated serial number to display, you need to be logged into the
system with Administrator rights.
To update your serial number
1Launch Stitcher.
2Select Help > Activate.
3In the Stitcher Activation window, enter your product serial number.
4Click Activate.
NOTE If you have lost your serial number, contact the Autodesk Business Center (ABC) at
800-538-6401 for assistance.
5Click Close.
6Exit Stitcher and restart for the updated activation to take effect.
NOTE To see the updated serial number in Vista, exit the product, right-click the product
icon, and click Run as an Administrator.
