Tagging SVG

Hi Tilman, your question about text rendering has been answered in the meantime. At this opportunity I saw that the tagging you are using for SVG is suboptimal.
Please, don't categorize into Valid SVG and into Created with Inkscape! Rather categorize into Valid SVG created with Inkscape.
Better will be into one of its subcategories as Valid SVG created with Inkscape:Diagrams.
Best might be to use e.g. Valid SVG created with Inkscape:Hasse diagrams. The tagging is easy as you can see at your Nested set V4; elements in Hasse diagram.svg.
Not any problem if you prefer other subcategories. Of course the tagging can occur in the description, but there is as well an own field for the tag (SVG rozwój).
If you have any other question about that, or when I can help you to categorize your fine work, please just tell me. sarang♥사랑 05:51, 17 June 2016 (UTC)

Hi Sarang, your templates are sophisticated, but really not easy to use. (I will think about writing a Python script that generates the right template parameters after selecting options from a menu.) You used |other fields={{Igen|+|s=hd}} and it generated the SVG development field in the table. But in File:8-cube matrix.svg I used |other fields={{Igen|T|s=:Diagrams}}, and the boxes are outside of the table now. Watchduck (quack) 08:40, 17 June 2016 (UTC)

To have them inside the table use the "+" parameter: |other fields={{Igen|T|+|s=d}}. That will work! sarang♥사랑 05:41, 20 August 2016 (UTC)

Category:Genji chapter symbols

User:Lipedia, User:Boolean_Algebra, User:Mate2Code, User:Watchduck, User:WatchDuck -- Why did you place Category:Genji chapter symbols in Category:Language-neutral diagrams, when not all images in that category are Language-neutral diagrams? -- AnonMoos (talk) 07:46, 27 August 2016 (UTC)

I took it from your file File:Genji chapter symbols groupings of 5 elements.svg, and thought that the symbols themselves are the "diagrams" in question. But a view at Category:Language-neutral diagrams shows me, that "diagrams" refers to the complete images. Thanks for the hint. Watchduck (quack) 11:07, 27 August 2016 (UTC)

File:Inkscape radial gradient test; red displayed as green.svg

The file you uploaded had inconsistent conflicting "stop-color" specifications. In the following code fragment, how is the SVG renderer supposed to know whether you want #0a0 or #bf0000? Doing either one really could not be called an error... AnonMoos (talk) 06:30, 19 November 2016 (UTC)

      <stop
         offset="0.48611075"
         stop-color="#0a0"
         id="stop14570-682"
         style="stop-color:#bf0000;stop-opacity:1" />

Thanks. I will be suspicious of the style attribute in SVG code generated by Inkscape. --Watchduck (quack) 11:57, 19 November 2016 (UTC)

Permutohedron

Hi Tilman. Two of your graphics that appear on the 'Permutohedron' page (and other places) appear to have errors.

In the file 'Symmetric group 4; permutohedron 3D; l-e factorial numbers.svg' the vertices are labeled correctly but the edge coloring is wrong. If the edge coloring indicates the coordinate transpositions where blue swaps (1 2), green swaps (2 3) and red swaps (3 4), then the edges of all 6 squares should alternate between red and blue and the 12 edges interconnecting the squares should all be green.

In the file 'Symmetric group 4; Cayley graph 1,2,6 (3D).svg', the edge coloring is correct but the vertices may be labeled wrong. I'm not sure since I don't understand the difference between a permutohedron and Cayley graph. The section on Cayley labeling is somewhat opaque; perhaps the Cayley labeling should be 'the inverse of the permutation given by its coordinates'. So coordinate (1,2,3,4) should be labeled (4,3,2,1)?

In other words, a fully correct image of an order 4 permutohedron can be generated by combining the vertices and edges from the first graphic with the edge coloring of the second. Tomldavis (talk) 01:10, 30 December 2016 (UTC)

Hi. Please take a look at v:Inversion_(discrete_mathematics)#Weak_order_of_permutations, and see if it clarifies this indeed confusing topic for you. Dont forget to open the box with the Cayley graph. The permutohedron is not the Cayley graph, so of course the colors are not what you would expect in a Cayley graph. They just illustrate which digit of the vector below the permutation changes. Watchduck (quack) 01:21, 30 December 2016 (UTC)

Moving subdivision triangles category

Thank you for your work on the math categories. I've moved a few categories that you've created:

• Category:Conway polyhedra; subdivision triangles -> Category:Subdivision triangles
• Category:Conway polyhedra; ortho-subdivision triangles -> Category:Ortho subdivision triangles
• Category:Subdivision n triangle‎ -> Category: Parallel subdivision triangles

And created a new category, Category:Skew subdivision triangles, that I'll be filling shortly. Sorry if I didn't give you much notice, but those categories were fairly new, and the semicolon in the names was going to interfere with my upload tool. -Apocheir (talk) 23:06, 26 January 2017 (UTC)

If you move a category, please move also the files. (Currently I see images on this redirect page.) You can use Cat-a-lot to do that.

Semicolons in category names interfere with your upload tool?! Then you are using a horrible upload tool, and you should stop using it. That tool should use a pipe instead (like Commonist does).

You removed Category:Triangular tilings and Category:Yellow triangles. Do you think these images should not be in these categories, or do you mean to add them in a different way?

In short: Do what you think is right, but please finish what you start. Watchduck (quack) 23:48, 26 January 2017 (UTC)

Category:Latin squares

Why did you remove the category "Latin Squares" from some Cayley tables? --Roderich Kahn (talk) 13:10, 25 January 2020 (UTC)

Because I put the whole category Cayley tables in Latin squares. All Cayley tables are Latin squares.

I have also removed them from Group theory, because they are already in that through Cayley tables (COM:OVERCAT).

And I just put them in their own set, so the context is not lost when they get scattered in subcategories. Watchduck (quack) 13:35, 25 January 2020 (UTC)

Polyhedron “shells”

I’ve noticed that your polyhedron models, including those of star polyhedra, are hollow. For someone looking to 3D print these models, that’s probably most convenient. But given that Wikipedia’s 3D viewer (among others) allows one to gaze into the interior of these shapes, it’s also useful to have a “full” version with all its inner structure.

I was thinking that your files could be renamed to something like [Polyhedron name] (shell).stl, so that the full versions [Polyhedron name].stl are the default, while preserving the shells for anyone who wants them. What do you think? OfficialURL (talk) 07:37, 10 April 2020 (UTC)

@OfficialURL: I am pretty sure, that you are confusing me with that other Tilman(n): User:TilmannR Anyway, I disagree with your idea, that file names should be reserved for files that may never be created. Those new files can easily have a "(solid)" appended. Watchduck (quack) 11:01, 10 April 2020 (UTC)

You're probably right, I shouldn't change preexisting names. What I did instead is upload my own files as [Polyhedron name] (full).stl, and link to the hollow versions. Also, sorry for thinking you were someone else. – OfficialURL (talk) 17:50, 10 April 2020 (UTC)

apologize for a six year ago thing

I am sorry to have caused Commons so much trouble.

Six years ago, I wasn't familar with the copyright policy, and thus I have uploaded 60 coviright-violated images. At that time, I took a copyrighted hanafuda and traced it for my own convenience, because someone at the Village Pump in Chinese Wikipedia said that such action might not violate the copyright regulations. I have to apologize for this.

During 2016-2020, I have learnt a lot about the policies and guidelines. However, I totally forgot those 60 copyvio images I have uploaded, so I did not request for deletion earlier. I am also really sorry for this.

I promise that if I encounter similar situation in the future, I will definitely check the copyright of the elements throughly, and will not upload them if I am unsure of it.

I am really sorry that I uploaded those images without checking if they are copyright-free or not and causing so much trouble to the Commons community.--A2569875 (talk) 15:51, 22 April 2020 (UTC)

Bilder/Graphiken bzgl. Musik

Hallo!

Bist du noch auf der WP aktiv? Deine Graphiken sind wirklich gut und ich würde dir sehr gerne ein paar kleine Fragen zu ihnen stellen, insbesondere zum Riemanschem Tonnetz, welches ich vor vielen Jahren schon in einem musiktheoretischen Buch von De la Motte gefunden hatte und welches dem Quintenzirkel m.E. deutlich überlegen ist, wenn man erst mal ein gewisses Level erreicht hat. Leider gibt es zwar eine Version nur mit Zahlen, aber keine Version, die aussschliesslich mit den Namen der Noten beschriftet ist. Da ich selber Musik mache, wäre ich also stark daran interessiert, die Vorlage zu bekommen, um eine (oder auch mehrere) an meine Bedürfnisse angepasste Version(en) zu kreieren. Ich gucke bald nochmal hier rein, weil ich selber kein Konto habe.

Beste Grüsse! 84.148.212.89 04:17, 2 June 2020 (UTC)

Hi. Ich bin eher auf Commons als in der Wikipedia aktiv. Fragen kannst du mir gerne stellen - am besten auf der Diskussionsseite der Kategorie oder des jeweiligen Bildes. Die Grafiken sind alle SVGs und können direkt bearbeitet werden. Das übliche Programm dafür ist Inkscape. Die Buchstaben habe ich zu Pfaden konvertiert, d.h. du kannst sie nicht mehr mit dem Textwerkzeug bearbeiten, sondern nur ersetzen. (Die Neuerungen solltest du dann auch in Pfade konvertieren.) Die Schriftart sollte Arial sein. Grüße, Watchduck (quack) 07:52, 2 June 2020 (UTC)

Serif or not serif ...

Hello Watchduck,

the discription of File:Quotation marks and similar signs.svg starts with: “The following text in Times New Roman, showing German and English quotation marks (Anführungszeichen) and similar-looking signs”.

Because of the picture shown, I tend to believe in a sans-serif facetype. However, Times New Roman is a serif font.

If I am not mistaken, would you have a look there?

Thanks. --Dirk123456 (talk) 15:35, 10 August 2020 (UTC)

@Dirk123456: I don't understand what you mean. The image shows text in TNR (converted to SVG paths), and it does contain serifs. Look e.g. at the letters "n" and "x".

Did you maybe confuse the text in the description for an image?

, ‚de‘en’ éàő 1' 2" x′ y″ „de“en”

Greetings, Watchduck (quack) 16:36, 10 August 2020 (UTC)

Yes, I confused the text in the description for an image. It was because the formatting:

<span style="font-size: 300%; font-weight: bold;">, ‚de‘en’ éàő 1' 2" x′ y″ „de“en”</span>

The formatted text looks like an image. Thank you very much for yor help.

Tesseract projection

I looked everywhere for your email since I don't have a wiki account. On the Wikipedia page for the tesseract one of your files is used with the caption: "The tetrahedron forms the convex hull of the tesseract's vertex-centered central projection. Four of 8 cubic cells are shown. The 16th vertex is projected to infinity and the four edges to it are not shown." I apologize for not understanding but can you please elaborate how this is a projection of a tesseract? What does it mean that the 16th vertex is projected to infinity? I assume that is why it and the 4 other cells are missing but there is not enough context for a poor non-mathematician like myself. In what sense is this the vertex centered central projection? I have an intuitive understanding of other common projections of 4D polytopes but this is a stumbling block.

I will run with the hypothesis that your same projection techniques would turn a cube into a triangle. Commonly, an orthographic projection is given which depicts a cube as a hexagon, so why are 3 corners coming inward to become the sides of a triangle in this kind of projection? As for the eighth corner I would say it's behind the first. Not sure what "infinity" has to do with it.

Thank you for your time

Cube as triangle and tesseract as tetrahedron

Try it out for two and then for three dimensions. Project a square from one of its vertices on a line. You get three points connected by two edges. Project a cube on a plane from one of its vertices, and you indeed get something with a triangular hull. You see it on the right.

Writing stuff like "projected to infinity" is not very self-explaining indeed. But yeah ... the projection center can not be projected. So within the logic of the projection, the last vertex is everywhere around you, but infinitely far away.

Instead of "Four of 8 cubic cells are shown" it would be more precise to write, that four are shown with recognizable cube geometry and the other four are shown as the faces of the tetrahedron. Watchduck (quack) 02:17, 2 September 2020 (UTC)

category:Cross section of the cube

Hello Watchduck,

I'm french and I speack english very bad. Sorry. I 'll try to explain this categry. I think, it's not an Commons:Image sets but a real geometric theme. I found other picture about troncature and other cube cross sections. I chose a more relevant categories. Do you agree with my modifications? Chears. HB (talk) 16:43, 26 September 2020 (UTC)

(Bonjour Watchduck, désolée, je suis française et parle mal anglais. Je ne pense pas que la catégorie «Cross section of the cube» soit un jeu d'images d'un même style et d'un même auteur. C'est une catégorie destinée à recevoir des images concernant un vrai sujet géométrique : les sections d'un cube par un plan.

Category:Cyrillic upper- and lower-case pairs with font lines

Hello, thanks for creating the set categories. I would create similar categories for the Latin script if you don‘t mind (as well as container categories where appropriate). However, one issue I found is that Category:Cyrillic letters on 7 font lines (serif with big margin) should, by its literal scope, also contain File:Cyrillic letter multiocular O (2).svg and File:Cyrillic letter unblended uk.svg, even if they do not depict an upper- and lower-case pair (similarly for File:Cyrillic letter Multiocular O.svg with Category:Cyrillic letters on 5 font lines (serif with big margin)). This might seem insignificant at first; however, for Latin letters, there are much more cases of this. The question is whether the upper- and lower case pair subsets should be split up from the set categories, in which case the Cyrillic set categories would contain that subset and two files (I don't think that would be problem), or not, in which case the non-set categories for upper- and lower case pairs would still be crowded. I think I'm leaning towards the first option. 𝟙𝟤𝟯𝟺𝐪𝑤𝒆𝓇𝟷𝟮𝟥𝟜𝓺𝔴𝕖𝖗𝟰 (𝗍𝗮𝘭𝙠) 21:07, 6 January 2021 (UTC)

Ask permission

Hello,

I wanted to ask if I have permission to use your images about Catalan solids and name their parts like this in Persian and English.

Thanks for your attention,

Sincerely yours, Hirbod Foudazi2 (talk) 09:10, 16 August 2021 (UTC)

Hi, you do not need my permission to do this, but I whish you would not do it. I think these images are absolutely pointless. To explain what verices, edges and faces are, one will use a simple solid like a cube. There is also no need for horrible images like this one. If this would be useful, I would have rendered it. (The result would look something like this.) I think it would be great, if you propose all your geometry images for deletion. If you really have to paint around in my images, please do not list me as author, but correctly mark them as derivate works. For this crop I am the author, but I ask you not to crop my images for me. (Especially not as JPGs with names completely different from mine.) Oh, and you know, that JPGs are for photos, right? If at some point you start creating good geometry images, find a way to save them as PNG. Sorry if this sounds harsh, but I am just trying to keep you from wasting your time and our time. Piles of low quality images just make it hard to find the useful ones between them. Greetings, Watchduck (quack) 10:45, 17 August 2021 (UTC)

Hello,

Ok I won't make low quality images any more. I can't make Pngs because I work with mobile. The image you said isn't for naming parts of polyhedron. It is a great stellated dodecahedron in its convex hull. (I wouldn't have made it if I knew you had made a similar image before). I can't nominate all of them for deletion because I made some of them to use in Persian Wikipedia articles.

Thanks for your attention, Sorry about delay,

Sincerely yours, Hirbod Foudazi2 (talk) 10:51, 18 August 2021 (UTC)

I think this is the best image I've created. I want to nominate the photo you mentioned for deletion, how should I do it? Hirbod Foudazi2 (talk) 10:54, 18 August 2021 (UTC)

Hi. Thanks for not taking my remarks personally. When I want to get rid of files I uploaded, I just add them to a category like this and (after a while) make a mass deletion request like this. Yes, I agree that this image is kind of useful, because it shows the false edges and vertices. But one or two images of that kind should be enough. No need to delete this one either - but also no need to create more like it. I would also like to keep this one, because interestingly it looks clearer than the PNGs. (Maybe JPG really looks better, but there is a consensus, that such files should be PNG.) You should start using Inkscape btw. You can put a raster image in one layer, and a description in another one. (See images like these.) There is also a fancy way to make multilingual labels in the same SVG file. See the same file in Farsi and Russian. Greetings, Watchduck (quack) 10:19, 21 August 2021 (UTC)

Hello. Is File:Dehn invariant 0.jpg useful? Hirbod Foudazi2 (talk) 09:38, 23 August 2021 (UTC)

No, it is not. This would be fine as a blackboard sketch, but we do not need images in blackboard quality on Commons. The perspective is bad, and the hidden lines are missing. The edge colors are not helpful. (You should use face colors to distinguish the two components.) And it should absolutely not be a JPG. You should learn to use Inkscape, before you upload geometry images on Commons. Greetings, Watchduck (quack) 14:27, 23 August 2021 (UTC)

Hello. Because I can only use an IPad in order to make files, so I prefer not to upload geometry images. Could you please make a better version of this image?

BTW, in this list it would make sense to use the same 3D images as in Archimedean solid, so the colors match with the vertex figure images.

GRB → RGB in your Euler diagrams?

Hallo Watchduck, arbeite seit über 20 Jahren auch als Nachhilfelehrer, und da ist es meine Erfahrung, dass Zugeständnisse an unsere Sehgewohnheiten, auch wenn diese ja im Grunde willkürlicher Natur sind, stets eine große Hilfe für die Verständlichkeit von Illustrationen sind. Und so ist es aus meiner Sicht ein Vorteil, bei der Illustration der Syllogismen für die Darstellung von "S", "M" und "P" die Farben Rot, Grün und Blau nicht nur als solche, sondern auch in dieser uns vom Farbspektrum, Regenbogen u.dgl. "intuitiv" vertrauten Reihenfolge zu wählen. Was hielten Sie also davon, die in Ihren Euler-Diagrammen gewählte Farbcodierung von Grün für "S" und Rot für "M" dementsprechend zu ändern, also die SVGs noch einmal so zu überarbeiten, dass Rot für "S" und Grün für "M" steht? Ich selber nämlich habe dazu leider nicht die Skills, konnte das nur im PNG-Format (siehe zB. file:Modus Barbara (Euler) RGB.png) realisieren, für Sie dagegen dürfte das wahrscheinlich eine Kleinigkeit sein. --Qniemiec (talk) 22:38, 11 March 2022 (UTC)

Hallo Qniemiec, ich halte das für keine gute Idee. Rot ist vor allem die Farbe, in der man markiert was wichtig ist. Und der Mittelbegriff beim Syllogismus ist zweifellos wichtiger als die anderen, weil er in beiden Urteilen vorkommt. Deshalb habe ich das bewusst so gewählt. Ich denke du überschätzt den Konsens über die richtige oder intuitive Reihenfolge der drei Farben. Grüße, Watchduck (quack) 08:30, 12 March 2022 (UTC)

Hmmm, ja der Mittelbegriff ist in der Tat das "Scharnier", fliegt dadurch am Ende in cer Conclusio aber stets raus, sodass sich die Frage stellt, welche beiden Farben dann dort die beiden sich gegenüberstehenden "Pole" S und P repräsentieren sollen. Bei der Polarität von Spannungsquellen und auch bei Temperaturen sind das ja Blau (für Minus oder kalt) und Rot (für Plus oder warm), bei Magneten dagegen Grün (für den Nordpol) und wieder Rot (nun für den Südpol) - da hat also selbst die Physik sich nicht auf eine einheitliche Farbcodierung einigen können, und mit Deiner Farbkombination Grün-Blau kommt nun auch noch die dritte mögliche hinzu... Ist halt das alte Thema mit der "intuitiven Benutzerführung", an der schon mancher Computerneuling erstmal verzweifelt ist, weil seine Intuition halt eine andere als die der Programmierer war. Zum Glück können unsere beiden Intuitionen ja in der Wikipedia, solange klar ist, was mit welcher Farbe gemeint ist, auch ohne sich in die Haare zu kriegen, koexistieren. :-) Schöne Grüße --Qniemiec (talk) 19:13, 12 March 2022 (UTC)

Hallo, hab gesehen, dass Sie meine Uploads in eine neue Kategorie umgesiedelt haben, danke. Wusste nicht, dass die andere für "M" in Rot reserviert war, las sich so, als ob da lediglich PNG statt SVG das Kriterium gewesen sei. Und dann - peinlich, peinlich! - habe ich auf meinem Upload zu AAA-1 auch glatt noch 'nen Fehler entdeckt: bei der Conclusio oben links (SaP) war "S" immer noch grün statt nun rot. ;-) Schöne Grüße Qniemiec (talk) 21:45, 12 March 2022 (UTC)

Rot, gelb und grün könnte ich mir auch vorstellen. Also mit Gelb für den Mittelbegriff. Muss ich mal drüber nachdenken. --Watchduck (quack) 13:38, 13 March 2022 (UTC)

Hidden categories

I think that these categories should be hidden, as it is user category by name and all user categories are hidden by definition. For this instance, Category:SVG Iberian shields shouldn't be hidden, but Shields by User:XYZ should be. — Draceane ^talk_contrib. 19:59, 11 July 2022 (UTC)

This is a misunderstanding. Image sets are not user categories. But typically the images in a set are all created by the same user, and therefore some sets are named after the user. The alternative is to just use numbers like Heraldic crowns of France set 1 (which could be named "by Eusebius"). and set 2 (which could be named "by Sodacan"). --Watchduck (quack) 20:05, 11 July 2022 (UTC)
