       transformation or translation of a Source form, including but
       not limited to compiled object code, generated documentation,
       and conversions to other media types.

       "Work" shall mean the work of authorship, whether in Source or
       Object form, made available under the License, as indicated by a
       copyright notice that is included in or attached to the work
       (an example is provided in the Appendix below).

       "Derivative Works" shall mean any work, whether in Source or Object
       form, that is based on (or derived from) the Work and for which the
       editorial revisions, annotations, elaborations, or other modifications
       represent, as a whole, an original work of authorship. For the purposes
       of this License, Derivative Works shall not include works that remain
       separable from, or merely link (or bind by name) to the interfaces of,
       the Work and Derivative Works thereof.

       "Contribution" shall mean any work of authorship, including
       the original version of the Work and any modifications or additions
       to that Work or Derivative Works thereof, that is intentionally

       "Contributor" shall mean Licensor and any individual or Legal Entity
       on behalf of whom a Contribution has been received by Licensor and

    2. Grant of Copyright License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.

    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       (except as stated in this section) patent license to make, have made,
       use, offer to sell, sell, import, and otherwise transfer the Work,
       where such license applies only to those patent claims licensable
       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.

    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:

       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and

       (b) You must cause any modified files to carry prominent notices
           stating that You changed the files; and

       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and

       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.

       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.

    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.

    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.

    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.

    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.

    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

    license, subject to third party intellectual property claims:

    (a) to use, reproduce, modify, display, perform, sublicense and distribute the
    Original Code (or portions thereof) with or without Modifications, or as part of a
    Larger Work; and

    (b) under patents now or hereafter owned or controlled by Initial Developer, to make,
    have made, use and sell ("Utilize") the Original Code (or portions thereof), but
    solely to the extent that any such patent is reasonably necessary to enable You to
    Utilize the Original Code (or portions thereof) and not to any greater extent that
    may be necessary to Utilize further Modifications or combinations.

    2.2. Contributor Grant.
    Each Contributor hereby grants You a world-wide, royalty-free, non-exclusive license,
    subject to third party intellectual property claims:

    (a) to use, reproduce, modify, display, perform, sublicense and distribute the
    Modifications created by such Contributor (or portions thereof) either on an
    unmodified basis, with other Modifications, as Covered Code or as part of a Larger
    Work; and

    (b) under patents now or hereafter owned or controlled by Contributor, to Utilize the
    Contributor Version (or portions thereof), but solely to the extent that any such
    patent is reasonably necessary to enable You to Utilize the Contributor Version (or
    portions thereof), and not to any greater extent that may be necessary to Utilize
    further Modifications or combinations.

    3. Distribution Obligations.

    3.1. Application of License.
    The Modifications which You create or to which You contribute are governed by the
    terms of this License, including without limitation Section 2.2. The Source Code
    version of Covered Code may be distributed only under the terms of this License or a
    future version of this License released under Section 6.1, and You must include a
    copy of this License with every copy of the Source Code You distribute. You may not
    offer or impose any terms on any Source Code version that alters or restricts the
    applicable version of this License or the recipients' rights hereunder. However, You
    may include an additional document offering the additional rights described in Section
    3.5.

    3.2. Availability of Source Code.
    Any Modification which You create or to which You contribute must be made available
    in Source Code form under the terms of this License either on the same media as an
    Executable version or via an accepted Electronic Distribution Mechanism to anyone to
    whom you made an Executable version available; and if made available via Electronic
    Distribution Mechanism, must remain available for at least twelve (12) months after
    the date it initially became available, or at least six (6) months after a subsequent
    version of that particular Modification has been made available to such recipients.
    You are responsible for ensuring that the Source Code version remains available even
    if the Electronic Distribution Mechanism is maintained by a third party.

    3.3. Description of Modifications.
    You must cause all Covered Code to which you contribute to contain a file documenting
    the changes You made to create that Covered Code and the date of any change. You must
    include a prominent statement that the Modification is derived, directly or indirectly,
    from Original Code provided by the Initial Developer and including the name of the
    Initial Developer in (a) the Source Code, and (b) in any notice in an Executable
    version or related documentation in which You describe the origin or ownership of the
    Covered Code.

    3.4. Intellectual Property Matters

    (a) Third Party Claims.
    If You have knowledge that a party claims an intellectual property right in particular
    functionality or code (or its utilization under this License), you must include a text
    file with the source code distribution titled "LEGAL" which describes the claim and the
    party making the claim in sufficient detail that a recipient will know whom to contact.
    If you obtain such knowledge after You make Your Modification available as described in
    Section 3.2, You shall promptly modify the LEGAL file in all copies You make available
    thereafter and shall take other steps (such as notifying appropriate mailing lists or
    newsgroups) reasonably calculated to inform those who received the Covered Code that new
    knowledge has been obtained.

    (b) Contributor APIs.
    If Your Modification is an application programming interface and You own or control
    patents which are reasonably necessary to implement that API, you must also include
    this information in the LEGAL file.

    3.5. Required Notices.
    You must duplicate the notice in Exhibit A in each file of the Source Code, and this
    License in any documentation for the Source Code, where You describe recipients' rights
    relating to Covered Code. If You created one or more Modification(s), You may add your
    name as a Contributor to the notice described in Exhibit A. If it is not possible to
    put such notice in a particular Source Code file due to its structure, then you must
    include such notice in a location (such as a relevant directory file) where a user
    would be likely to look for such a notice. You may choose to offer, and to charge a fee
    for, warranty, support, indemnity or liability obligations to one or more recipients of
    Covered Code. However, You may do so only on Your own behalf, and not on behalf of the
    Initial Developer or any Contributor. You must make it absolutely clear than any such
    warranty, support, indemnity or liability obligation is offered by You alone, and You
    hereby agree to indemnify the Initial Developer and every Contributor for any liability
    incurred by the Initial Developer or such Contributor as a result of warranty, support,
    indemnity or liability terms You offer.

    3.6. Distribution of Executable Versions.
    You may distribute Covered Code in Executable form only if the requirements of Section
    3.1-3.5 have been met for that Covered Code, and if You include a notice stating that
    the Source Code version of the Covered Code is available under the terms of this
    License, including a description of how and where You have fulfilled the obligations of
    Section 3.2. The notice must be conspicuously included in any notice in an Executable
    version, related documentation or collateral in which You describe recipients' rights
    relating to the Covered Code. You may distribute the Executable version of Covered Code
    under a license of Your choice, which may contain terms different from this License,
    provided that You are in compliance with the terms of this License and that the license
    for the Executable version does not attempt to limit or alter the recipient's rights in
    the Source Code version from the rights set forth in this License. If You distribute the
    Executable version under a different license You must make it absolutely clear that any
    terms which differ from this License are offered by You alone, not by the Initial
    Developer or any Contributor. You hereby agree to indemnify the Initial Developer and
    every Contributor for any liability incurred by the Initial Developer or such
    Contributor as a result of any such terms You offer.

    3.7. Larger Works.
    You may create a Larger Work by combining Covered Code with other code not governed by
    the terms of this License and distribute the Larger Work as a single product. In such a
    case, You must make sure the requirements of this License are fulfilled for the Covered
    Code.

    4. Inability to Comply Due to Statute or Regulation.

    If it is impossible for You to comply with any of the terms of this License with
    respect to some or all of the Covered Code due to statute or regulation then You must:
    (a) comply with the terms of this License to the maximum extent possible; and (b)
    describe the limitations and the code they affect. Such description must be included in
    the LEGAL file described in Section 3.4 and must be included with all distributions of
    the Source Code. Except to the extent prohibited by statute or regulation, such
    description must be sufficiently detailed for a recipient of ordinary skill to be able
    to understand it.

    5. Application of this License.

    This License applies to code to which the Initial Developer has attached the notice in
    Exhibit A, and to related Covered Code.

    6. Versions of the License.

    6.1. New Versions.
    Floris van den Berg may publish revised and/or new versions of the License from time to
    time. Each version will be given a distinguishing version number.

    6.2. Effect of New Versions.
    Once Covered Code has been published under a particular version of the License, You may
    always continue to use it under the terms of that version. You may also choose to use
    such Covered Code under the terms of any subsequent version of the License published by
    Floris van den Berg No one other than Floris van den Berg has the right to modify the
    terms applicable to Covered Code created under this License.

    6.3. Derivative Works.
    If you create or use a modified version of this License (which you may only do in order
    to apply it to code which is not already Covered Code governed by this License), you
    must (a) rename Your license so that the phrases "FreeImage", `FreeImage Public License",
    "FIPL", or any confusingly similar phrase do not appear anywhere in your license and
    (b) otherwise make it clear that your version of the license contains terms which differ
    from the FreeImage Public License. (Filling in the name of the Initial Developer,
    Original Code or Contributor in the notice described in Exhibit A shall not of
    themselves be deemed to be modifications of this License.)

    7. DISCLAIMER OF WARRANTY.

    COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS, WITHOUT WARRANTY OF
    ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, WITHOUT LIMITATION, WARRANTIES THAT
    THE COVERED CODE IS FREE OF DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR
    NON-INFRINGING. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED CODE
    IS WITH YOU. SHOULD ANY COVERED CODE PROVE DEFECTIVE IN ANY RESPECT, YOU (NOT THE INITIAL
    DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE COST OF ANY NECESSARY SERVICING, REPAIR OR
    CORRECTION. THIS DISCLAIMER OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO
    USE OF ANY COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.

    8. TERMINATION.

    This License and the rights granted hereunder will terminate automatically if You fail
    to comply with terms herein and fail to cure such breach within 30 days of becoming
    aware of the breach. All sublicenses to the Covered Code which are properly granted
    shall survive any termination of this License. Provisions which, by their nature, must
    remain in effect beyond the termination of this License shall survive.

    9. LIMITATION OF LIABILITY.

    UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT (INCLUDING NEGLIGENCE),
    CONTRACT, OR OTHERWISE, SHALL THE INITIAL DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY
    DISTRIBUTOR OF COVERED CODE, OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO YOU
    OR ANY OTHER PERSON FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF
    ANY CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL, WORK STOPPAGE,
    COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER COMMERCIAL DAMAGES OR LOSSES, EVEN
    IF SUCH PARTY SHALL HAVE BEEN INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS
    LIMITATION OF LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY
    RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW PROHIBITS SUCH
    LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF INCIDENTAL OR
    CONSEQUENTIAL DAMAGES, SO THAT EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.

    10. U.S. GOVERNMENT END USERS.

    The Covered Code is a "commercial item," as that term is defined in 48 C.F.R. 2.101 (Oct.
    1995), consisting of "commercial computer software" and "commercial computer software
    documentation," as such terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with
    48 C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995), all U.S.
    Government End Users acquire Covered Code with only those rights set forth herein.

    11. MISCELLANEOUS.

    This License represents the complete agreement concerning subject matter hereof. If any
    provision of this License is held to be unenforceable, such provision shall be reformed
    only to the extent necessary to make it enforceable. This License shall be governed by
    Dutch law provisions (except to the extent applicable law, if any, provides otherwise),
    excluding its conflict-of-law provisions. With respect to disputes in which at least one
    party is a citizen of, or an entity chartered or registered to do business in, the The
    Netherlands: (a) unless otherwise agreed in writing, all disputes relating to this
    License (excepting any dispute relating to intellectual property rights) shall be subject
    to final and binding arbitration, with the losing party paying all costs of arbitration;
    (b) any arbitration relating to this Agreement shall be held in Almelo, The Netherlands;
    and (c) any litigation relating to this Agreement shall be subject to the jurisdiction of
    the court of Almelo, The Netherlands with the losing party responsible for costs,
    including without limitation, court costs and reasonable attorneys fees and expenses. Any
    law or regulation which provides that the language of a contract shall be construed
    against the drafter shall not apply to this License.

    12. RESPONSIBILITY FOR CLAIMS.

    Except in cases where another Contributor has failed to comply with Section 3.4, You are
    responsible for damages arising, directly or indirectly, out of Your utilization of
    rights under this License, based on the number of copies of Covered Code you made
    available, the revenues you received from utilizing such rights, and other relevant
    factors. You agree to work with affected parties to distribute responsibility on an
    equitable basis.
