Request

Could somebody please modify the above files representing the flag and coat of arms of Plomelin, so that they look closer to the way they actually should? The proper version of the flag can be seen here and here. And the full version of the arms can be seen here (albeit obviously without the captions at the top and bottom). Thanks.

Discussion

Is the dragon meant to be identical between the coat of arms and the flag? Just asking, since that coat of arms image that you sent is by far the highest quality version I've been able to find, so I'd like to use it as a reference for both.

@DeVos Max: Yes, I agree that the dragon from the version of the COA in the link should be used as a reference in the update of both files. Thanks for your interest! Snow Lion Fenian (talk) 15:52, 3 December 2024 (UTC)[reply]

I think the dragon shown on this drawing looks very close to the ones on the flag. I will vectorize this drawing from scratch and use it for the files.

Feitidede ☆ﾟ.* 20:10, 3 January 2025 (UTC)[reply]

@Snow Lion Fenian I have overwritten both files. I designed the new dragon from scratch based on the image linked above. Let me know if you find any issues.  Done Feitidede ☆ﾟ.* 04:31, 4 January 2025 (UTC)[reply]

 Undone: The overwritten versions of the arms and the flags have been restored, as these overwrites, mainly, are conflicting with Commons:Overwriting existing files ; morevoer, the specific design of an element doesn't make the arms or the flag invalid, thus current versions are fully compliant with their description. Ping @Bzh-99 and Jpgibert:

--Kontributor 2K (talk) 14:05, 4 January 2025 (UTC)[reply]

The current files have clear mistakes in rendering and are even flagged as improper SVGs. The current files also are not compliant with their description because they are missing the colleté d'hermine. The overwritten versions don't appear to vastly differ from the original ones. I can't believe these versions are being gate-kept from being improved. Feitidede ☆ﾟ.* 18:16, 4 January 2025 (UTC)[reply]

@Feitidede: Thank you for your undertaking of this request. Given the apparent dispute over the matter of overwriting the existing files, I would instead propose uploading the correct versions of the flag and arms as completely new files, for which I've provided potential titles above (both of which use the native Breton name of the town to avoid confusion with the existing files).

Also, and sorry that I didn't make this clearer in the original request, but the corrected version of the COA should actually have the surrounding embellishments along with the shield (namely the yellow crown/castle at the top, the yellow branches on both sides, and the intertwining scroll with the words "WAR EVEZ"), as in the link. Any chance that could be rectified in the new version of the file as well? Sorry again for the hassle. Snow Lion Fenian (talk) 01:08, 5 January 2025 (UTC)[reply]

  The receiver side of the system

Article(s)

GL Mk. I radar

Request

I would like to get separate illustrations of the two main parts of the system in this article, the transmitter and receiver. The image I've linked to above is the receiver. It is not obvious due to the low quality of the image, but the important part is a series of horizontal metal rods in front of the lower truss work that form the main antenna.

The only photograph I have found of the transmitter is here. It has even less detail than the image above though. I have also found an old illustration of it, but it is blacklisted so I can only suggest that one goes to https://en . topwar . ru to their page at /199210-britanskie-i-amerikanskie-radiolokatory-perioda-vtoroj-mirovoj-vojny-ispolzovavshiesja-v-sovetskoj-pvo.html. The image is about half way down the page (yellowish). The transmitter is overall very similar to the receiver in that it is a box on top of a gun carriage, and differs mostly in the details of the antenna and truss work.

It is quite difficult to see the receiver antennas in the photograph, you can see a series of rods at the top of the lower truss, but I don't believe that is them, there is another row of rods below it but they are very difficult to make out. The illustration also lacks detail of the receiver antenna, but they would look very similar to the two seen on the transmitter.

@Maury Markowitz Is it an line illustration like this or a more realistic (photo like) one you are looking for. --always ping me-- Goran tek-en (talk) 16:05, 9 January 2025 (UTC)[reply]

@Goran tek-en: The first reference has the best quality and I think mostly you can use that as a guide. The first of the two images is the transmitter, which matches the one I have in the article. The active part of this system are a series of antenna "elements" (which together make the antenna as a whole) made from "have-wave dipoles", which are simply two wires placed end-to-end with a gap between them an a total length across the two one-half of the radio wavelength. The idea is like a guitar, if your "string" is one-half the wavelength of the note you play it will resonate, as long as you pluck it somewhere near the middle. Here you "pluck" it with an electrical generator connected at the mid-point.

An interesting detail that is only visible in this image (not the ones I had seen earlier) is that the antennas have an interesting L shape, which I have not seen before. The "active" part of the antenna elements are the horizontal portions, which match the layout/polarization of the receiver antennas. I'm not sure what role the vertical portion plays, and none of my references seem to mention it. It appears they have connections at the top, but those might be supports, not electrical connections. Very interesting! Also note that the antenna mounted on the ladder has the same arrangement, but in this case it is upside down.

The receiver is much simpler, with more "standard" horizontal elements. There are three of them along the main section, which you can make out in this image (barely) and then another mounted up top again. The idea was that the two on the outside part of the horizontal line would be compared to calculate the horizontal angle, and the upper one with the center to get the vertical angle. Also notice the whip-like vertical antennas behind the "ladder". There appear to be two of these, which strongly suggests they are IFF receivers. These are not part of the radar itself, they are a separate receiver tuned to the radios of friendly aircraft.

This page is very useful, excellent find!

@Goran tek-en: Yeah, any format will work, the line art you linked to is a good place to start. Maury Markowitz (talk) 19:46, 10 January 2025 (UTC)[reply]

@Maury Markowitz

Before I continue I need your feedback on some drafts. I might have gone to much into details but that is up to you to say, if you want a simpler cleaner illustration I can do that or I can make like this and then make another line version or so.

So give me feed back, just say what you think, thanks.

@Goran tek-en: I'm not sure I see much of a difference between the 100% an 200%, but that might be just my end. Of the four here, I think the first one is the best. It's clear but also has details. I don't think the shadows aid the visualization. Maury Markowitz (talk) 19:52, 14 January 2025 (UTC)[reply]

As I work in a svg file the uploaded file can be enlarged without loosing any details. So my intention with the 200% files was (as the are png) to show you a bit more details, you can zoom in more on them. --always ping me-- Goran tek-en (talk) 15:00, 15 January 2025 (UTC)[reply]

@Maury Markowitz

• I would need your help to understand the parts encircled here. I have found this picture where you can see it a bit better, but are they the same? Are they long-wave transmitters or what? If we know what they are maybe me can find better images.
• I also find those pages/images
  • image
  • page 17 here has a closer image.

Are those relevant for us? --always ping me-- Goran tek-en (talk) 12:14, 16 January 2025 (UTC)[reply]

@Goran tek-en: I am curious about those too! The actual antennas are connected to these objects. The antennas themselves cannot be seen in this photo though, but the very first URL you posted above (lookout point) does show the antennas themselves more clearly, they are the L-shaped objects. I believe the circled object is just a support rod of some sort, and not really important. If you look on that same image, it appears there are several more of these connected to the truss work, connecting at several points on the antenna, so I think this was just a mounting system that was intended to keep the antennas SOLIDLY fixed to the truss so you didn't have to re-adjust anything after moving the radar site.

The first of the two new URLs you posted solves a mystery! That image is clearly the basis for the line drawing I posted on the Russian page. It is very annoying they have watermarked this, as the image is in the public domain (it's PD-50 as UK crown). The receiver is the item in the center of the image, with transmitters on the left and right sides. The details of the receiver are slightly more obvious here, but it is still not great.

The French PDF also has several images of GL systems. The page "Grande Distance" shows a Mk. I transmitter on the right, I've not seen a description of what the smaller truss above the main one does but I suspect it is part of the EL attachment. On the Pas tous pareils page we see a more clear image of those "supports" in the upper right, but again the detail is lacking. The lower-right image shows the receiver in what I assume is the folded-up state for travel. Maury Markowitz (talk) 13:07, 16 January 2025 (UTC)[reply]

@Maury Markowitz Do you think the first image here shows what the antennas should look like? --always ping me-- Goran tek-en (talk) 14:07, 19 January 2025 (UTC)[reply]

@Goran tek-en: The antennas on the receiver will look just like this. These are classic "dipoles", the horizontal rods in this image. They don't look like it here, but they are two separate rods, one on either side of the supports. If you look at the second from the top on the left you can see the small gap between them, but it's not easily seen in the other ones.

On the transmitter van, the antennas are different and I've never found out why. On the transmitter, the dipoles have extensions that go up, and appear to be the same length as the horizontal part. So instead of two horizontal letter I's, pointed end-to-end like - -, it is two L shapes, like ⅃ L. The rods you were asking about earlier appear to be supports, like the ones visible in the link you just provided, but with another set of them holding the top of the L's. I hope that makes sense! Maury Markowitz (talk) 14:48, 20 January 2025 (UTC)[reply]

@Maury Markowitz

I need you to check this Draft transmitter-2 before I continue, thanks. --always ping me-- Goran tek-en (talk) 17:51, 22 January 2025 (UTC)[reply]

@Goran tek-en: That looks EXCELLENT! Maury Markowitz (talk) 18:02, 22 January 2025 (UTC)[reply]

@Maury Markowitz So you think it's more or less correct, there are details I had to guess or look at other images? --always ping me-- Goran tek-en (talk) 18:30, 22 January 2025 (UTC)[reply]

@Goran tek-en: The only think I see that is missing is the second antenna up the "ladder" but I assume that was going to be a later project. I think all the key details are here, and certainly all the ones I need for the description part that I want to use this image to help explain. Maury Markowitz (talk) 19:35, 22 January 2025 (UTC)[reply]

@Maury Markowitz

So now you have to check this Draft transmitter-3.I have made this png draft big so you can zoom in. I need your fresh eyes and knowledge to check this, thanks. --always ping me-- Goran tek-en (talk) 13:17, 1 February 2025 (UTC)[reply]

@Goran tek-en: The structure looks perfect. I have only two suggestions: you have colored most of the "support" structure in a sort of green-grey, and the antennas in silver-grey. The exception is the support bars that connect the upper part of the L shaped antennas to the top of the truss, which are dark-grey. I think these should be the green color like the other supports below. The other is perhaps make the antennas themselves "brighter" ("lighter", "more visible"?) so that they stand out a little better compared to the truss. Other that that I can't see any other changes.

@Goran tek-en: Sorry, I just thought it would be easier for me to type it in directly than type it here. But sure: "The GL Mk. II radar was a British radar system that was built starting in 1940, based on the earlier Mk. I units of 1939. The Mk. II consisted of two wooden cabins that were mounted on gun carriages that allowed them to rotate to point at targets. One, shown here, contained the transmitter electronics and antenna systems. The transmitter antennas are arranged in two parts, the four antenna elements making up the prominent horizontal row on the truss work, and a single similar antenna mounted above on the ladder-like support. The four horizontal antennas mixed together to narrow the beam down to about sixty degrees wide, while the single upper antenna mixed with the main signal to produce a series of vertical 'lobes' that allowed the altitude angle to be calculated. The transmitter and receiver shared a separate wheeled generator pack, not shown here." I found the working URL and added the caption. Maury Markowitz (talk) 19:24, 6 February 2025 (UTC)[reply]

Mníšek

Request

Hi! I was wondering if someone can kindly please vectorize the flag of the Czech town of Mníšek? The flag has a pattern of four parts bisected in a Nordic Cross manner though without an actual cross. On the top line, a white square on the left and a green rectangle on the right. On the bottom line, a red square on the left and a red white rectangle on the right. In the white square at the top is the emblem from Mníšek's coat of arms containing a yew leaf surrounded by rosary beads. In addition, there is a visual pun in the design, (what is known as "canting arms" in heraldry) where some of the beads in the rosary are replaced with actual roses. The black outline on the flag file posted is not actually part of the flag. I have included several other files that use similar design elements to use as bases so the request can be done more quickly). I'll be grateful to see it done.

Request

This image was kindly created by @TheWanderingTraders: in response to a request by me in January. Unfortunately, I did not realise that the label of the top vertex needs to be changed from "(a+c, b+d)" to "(a+b, c+d)" and I did not include that in my request. Someone at Talk:Determinant#Using_column_vectors_to_represent_points has now noticed that the image is not quite right.

Please can someone now make this change.

@JonH:  Done QuickQuokka ^{[⁠talk • contribs]} 07:19, 11 February 2025 (UTC)[reply]

Discussion

@JonH: Given your choice of (a,b) and (c,d), the top vertex should remain (a+c,b+d)... the top vertex label is not the problem. Looking at the second diagram on this web page, for the (a,b) and (c,d) you have chosen, the correct formula for Diagram A area is bc-ad—which yields a positive number. I've added Diagram B above, which has the (a,b) and (c,d) labels switched versus yours. Would you rather just use Diagram B which has the determinant-familiar ad-bc, or add "absolute value symbols to the formula in Diagram A? I'm not sure what the goal is with this request. Please clarify. —RCraig09 (talk) 04:27, 16 February 2025 (UTC)[reply]

To try to clarify this, I will set out some of the history:

• In 2007, File:Area parallellogram as determinant.svg was created with vertices (0, 0), (c, d), (a + c, b + d) and (a, b) reading anticlockwise.
• In 2009, it was changed to have vertices (0, 0), (a, b), (a + c, b + d) and (c, d).
• Years passed with no changes.
• In 2024, I started a discussion where I pointed out that the article Determinant used the row vectors of the matrix to represnt points, and that nowadays points are usually represented by column vectors, so the article could be simplified. The discussion confirmed this, but no change was made immediately.
• In January 2025, I made a request (now archived) to have a modified image with changes to two of the labels: from "(a, b)" to "(a, c)" and from "(c, d)" to "(b, d)".
• File:Area parallelogram as determinant modified was created with those two changes.
• The article Determinant was changed to be simpler and to use the modified image.
• On 7 February, it was pointed out at Talk:Determinant#Using_column_vectors_to_represent_points that the vertex (a + c, b + d) should now say (a + b, c + d). I had known back in 2024 that this change was needed, but I forget to include it in my first request. Sorry.
• On 10 February, I created this request to change the third vertex.
• On 11 February, @QuickQuokka: made the requested change, so the vertices were in the order (0, 0), (a, b), (a + b, c + d) and (b, d) reading anticlockwise.
• At 20:25 12 February, 2025 (UTC), I was happy with the changed image, so I noted on the Determinant talk page that it was now fixed, and clicked a link to thank QuickQuokka.
• An hour later, the image was changed to have the vertices in the order (0, 0), (c, d), (a + c, b + d) and (a, b).
• As @RCraig09: says, the diagram is now wrong because bc-ad is negative. But it is also wrong because it is using the row vectors to represent points and so it does not correspond to the text of the Determinant article.

The simplest fix is to revert File:Area parallelogram as determinant modified to the version dated 07:19, 11 February 2025. I can do that, but there has also been a change to the transparent background which might be desirable, so I will wait to allow further discussion.

By the way, the Stack Exchange page linked to above includes a diagram dated 1985, and seems to be using the older convention of row vectors to represent points. JonH (talk) 19:05, 23 February 2025 (UTC)[reply]

I have an engineering background and understand the math basics, but here on Wikimedia I'm a Graphics Dude who's waiting for a concise request or instruction on what exactly is needed. It sounds like JonH is calling for more discussion, so I'll not take any action until the goal is clearly expressed. —RCraig09 (talk) 22:52, 23 February 2025 (UTC)[reply]

Request

Was wondering whether someone wants to create a vector version of this file. It was originally uploaded as non-free content, but it's too simple to be eligible for copyright protection under US copyright law per c:COM:TOO US. The webp file doesn't look too bad, but this might work better as a vector version since the white background can then probably be removed. The file is eventually going to be moved to Commons; so, the vector version could be uploaded there as well. -- Marchjuly (talk) 13:11, 21 February 2025 (UTC)[reply]

Flag of Alaska, Flag of Connecticut, Flag of Oregon, Proposed flags of U.S. states

Request

Could anyone please create SVG files for the following three U.S. state flag proposals from 1976:

1) Joan Altabe's proposed flag for Alaska, as seen here (at the top).

2) Atle Grahl-Madsen's proposed flag for Connecticut, as seen here (at the top).

3) Jean-Claude Muller's proposed flag for Oregon, as seen here (at the bottom).

Thanks. Snow Lion Fenian (talk) 02:41, 26 February 2025 (UTC)[reply]

@Snow Lion Fenian I made the flags because they were simple, but I'm not sure if this competition is important enough to be mentioned in so many articles. Swiãtopôłk (talk) 20:16, 26 February 2025 (UTC)[reply]
