Commons:Captures de pantalla
Shortcuts: COM:SS • COM:SCREENSHOT • COM:SCREENSHOTS • COM:Screenshot
1. Que el programari tingui llicència lliure del propietari o que la captura de pantalla tingui llicència lliure segons el propietari del programari.
2. Que la captura de pantalla tingui llicència lliure segons el propietari del programari, llavors la imatge és adequada per a Commons sempre que estigui dins de l'abast.
Si no es compleixen les dues condicions, la imatge no és lliure i encara no és adequada per carregar-la a Commons.
Les captures de pantalla són obres derivades i, com a tals, estan subjectes al dret d'autor del contingut mostrat, pot ser un vídeo, un programa de televisió o un programa d'ordinador.[1] Per tant, les captures de pantalla no s'han de penjar a Wikimedia Commons tret que tot el contingut que hi hagi estigui sota una llicència lliure o sigui de domini públic.
Si no sou el propietari dels drets d'autor d'un programari, podeu publicar una captura de pantalla sota una llicència gratuïta només si tot el contingut que es mostra té una llicència gratuïta. Si una captura de pantalla conté icones o contingut no lliures, normalment tampoc no és lliure,[2] però es pot fer una excepció quan el contingut sigui de minimis.
Si tot el contingut mostrat és de domini públic, la captura de pantalla també ho és, perquè no s'afegeix cap contribució creativa en crear una captura de pantalla. Pot ser que això no sigui cert en totes les jurisdiccions, però es manté almenys als Estats Units (a causa de la Bridgeman Art Library v. Corel Corp.), a Alemanya (vegeu Bildrechte:Schutz für Reproduktionen per la la Viquipèdia alemanya), i probablement a tots els altres països de la Unió Europea.
Si els titular(s) dels drets d'autor (normalment els programadors, l'empresa de programari, el productor o l'emissora) no accepten publicar el programa amb una llicència gratuïta, les captures de pantalla normalment només són gratuïtes si llicencien explícitament la captura de pantalla (o totes les captures de pantalla) sota una llicència gratuïta.
Obres audiovisuals
Screenshots from audiovisual works (such as films, television broadcasts, video clips) are often the property of its producer or creator and they may not be uploaded to Commons unless the work itself is in the public domain or released under a free license or unless the copyright holder is willing to release the screenshot under a free license.
Programari
In most cases, screenshots of computer software (which include programs, video games, operating systems) cannot be uploaded to Commons unless the software is released under a free software license that complies with the Commons licensing policy (software released under licenses that meet the OSI definition of "Open Source" will meet the requirements), or there is formal permission.
Note that free programs generally are not free of intellectual property protections. Just as websites may be free to access, but still covered under copyright, simply because a software is free to download, run or play, does not mean that it is in the public domain or freely licensed in a way that is compatible with Commons. For those that are under a free license, you must still conform to the terms of the particular licence, which usually means you must publish your derivative work under the same licence, and correctly attribute the original authors or owners. However, screenshots of programs with a command-line interface may fall into public domain. See {{PD-text}} for more information.
Note, this does not prevent you from uploading works created using non-free software, it is not subject to the copyright of the software itself in most cases. This is especially true for fonts, which in some cases are considered programs.
Per crear una captura de pantalla lliure
- Use a free program with a completely free skin. (A KDE Program using Breeze theme is an example.) If you are using an operating system with a non-free theme (like Windows), make sure it fits something like {{PD-ineligible}}, e.g. has only flat-colored backgrounds and buttons and no complex icons. See Commons:Llindar d'originalitat for examples of images, or image modifications or other actions considered trivial or non-trivial in different countries.
- Cut away all possibly non-free elements. Only show the relevant content.
- The content of the screenshot must be free too. Make sure the screenshot does not contain non-free text or images.
- If the screenshot contains photos or other works (e.g. a shot of Wikipedia's main page), be sure to mention and follow the terms of each license.
- Save the file as a PNG.
Please tag screenshots that show only free content with {{Free screenshot}} in addition to an appropriate copyright tag. You must also indicate the free software license under which the program has been published.
Exemples
Productes de Microsoft
Microsoft's guidelines do not allow derivative works,[3] so screenshots of Microsoft products would go against Commons policy. The Windows operating system itself is a Microsoft product, and the precise appearance of standard operating system widgets in some themes may or may not be copyrightable, as they are purely geometric.
Programari com a art
In some cases the program itself is a work of art—an example would be a demoscene (such as one that is illustrated with the panda). Screenshots of such works are free if and only if the program itself is free. An exception to the rule is if the copyright holder of a non-free program wishes to freely license a screenshot of it. To do this, the user must have the rights to all visible non-free objects—the interface, the graphics, the text, everything. Before doing this, please consider all that it entails. Any design elements or logos appearing in the screenshot will irrevocably be placed under a free license. Also, be sure to make it explicitly clear that the software itself is not free.
Navegadors de web
Common proprietary web browsers include Internet Explorer, Safari, Opera and Microsoft Edge. Screenshots of these are never permissible on Commons if they show the browser's user interface.
Common free web browsers include Mozilla Firefox, Chromium, Konqueror, and GNOME Web. Screenshots of these browsers displaying free content should be permissible, so long as they do not include copyrightable elements of a proprietary operating system, other proprietary software or non-free user interface customizations. The Firefox icon before Firefox 3.6 is non-free, so it must not be included in screenshots (internal logo files from Firefox 3.6 to 12 are under the Mozilla tri-license and from Firefox 13 are under Mozilla Public License 2.0, although trademarked, so are acceptable where hard to avoid). GNU IceCat, a rebranded Firefox-based browser, is unencumbered by this problem, but may show small non-free logos under certain configurations, which should be replaced.
Google Chrome has caused conflicts; even though, besides its logo, there are no immediately visible differences between Chrome and its open source arm Chromium, it has been asserted that Google Chrome itself is non-free because its official binaries are subject to a non-free Google Chrome Terms of Service which overrides the open source terms of its base source code. Deletion discussions have gone both ways.
Screenshots of web browsers displaying web sites, images, videos or other copyrighted content which is not under a free license are not permissible.
Although Wikipedia is often a component of free screenshots, there have been issues.
- Most Wikimedia logos were previously subject to a proprietary license, but this changed when they were freed, in 2014.
- If the screenshot contains images or icons with free licenses with requirements, you have to honor them, such as by listing them and their authors and licenses, which may be other than Creative Commons Attribution-ShareAlike.
Telèfons intel·ligents
Although much of Android is open source software, this does not apply to Google software or their icons. Additionally, many smartphones do not include the "stock" Android user experience, but one specific to the company (such as Samsung Experience/One UI, previously TouchWiz and Huawei EMUI). These aspects are copyrighted by the maker of the phone, and screenshots showing portions of these interfaces (such as home screens) are not free.
Screenshots of "stock" Android can be tagged with {{Apache}} with copyright credit to "The Android Open Source Project".
As for the Apple iOS, per this failed undeletion request, the iOS software license agreement doesn't allow you to use {{APSL}} or other free licenses, hence unless if developers of a particular iOS app said to use their own free license (even so, you should cut the Apple-designed GUIs, i.e. drop-down list items, the "Home" buttons (either float or machinery)), they're violating our License policy.
