Nice job with the image on the Thaumatrope‎ page. You know your image markup! - DavidWBrooks (talk) 21:22, 21 January 2016 (UTC)

Hi DavidWBrooks, Thanks for your kind words – I try my best! cmɢʟee⎆τaʟκ 00:42, 6 June 2016 (UTC)

Hello from Brazil

Hi, I came here by Astronomy Picture of the Day and WOW! what a great artist you are!

First of all, in your "Burj Khalifa floors.svg" section, you wrote that "the test animation of falling snowflakes works in Chrome, but not in Firefox 26.0". Great news, it works in Firefox 42, maybe it works in previous versions greater than 26 also.

"Comparison of pyramids" is an amusing picture, I want someday to present a lecture about piramids so I can show it (giving you the credits, of course). "Ideal projectile motion for different angles" and "Fourier series square wave circles animation" are awesome!

You asked "Does anyone actually look at this? If so, I'd love to hear from you — cheers!" So cheers! And keep up the good work!

RaphaelRBarbosa (talk) 12:03, 26 January 2016 (UTC)

Hello Raphael! Thank you for your delightful message and compliments — it's wonderful to know that my contributions have made an positive impact to society and it inspires me to continue creating more.

Thanks, too, for letting me know that the snowflakes animation now works. I'll update the section accordingly.

Yes, please feel free to use the illustrations; if I could make just a tiny request, please link back to their description pages so that the reader can find the original image and give feedback, which will help improve them in the future.

Have a great day! cmɢʟee⎆τaʟκ 13:46, 26 January 2016 (UTC)

File:Malaysia tree diagram.svg

Hey Cmglee, thanks for the work you put on File:Malaysia tree diagram.svg awhile ago. It looks good, but I hope you don't mind if I request a couple of things. Firstly, would it be possible to change the font? I don't know if it's just my display, but the kerning feels quite off, with letters often too close together but occasionally far apart (eg. It looks like there's a space between SINGA and PORE in SINGAPORE). The font in the png for example is much easier to read for me, I think because it is more spaced out. Given that this image is meant to be displayed quite large, width isn't really an issue. Secondly, I see you changed the purple for the Labuan from its png version to be a bit more distinct. It'd be good if you took that a bit further, making it even more distinct. Thanks again for the work so far, CMD (talk) 17:39, 11 February 2016 (UTC)

Thanks for your compliments and feedback, Chipmunkdavis. Yes, thumbnail SVG font rendering is a known (and perpetual) issue e.g. see http://phabricator.wikimedia.org/T36947 — in this case probably made worse by my compressing the text horizontally to fit in single columns without appearing too small. The SVG file itself — http://upload.wikimedia.org/wikipedia/commons/3/3d/Malaysia_tree_diagram.svg — looks fine on my Chrome, IE and Firefox. Nevertheless, I tried changing the font to Helvetica/Arial and it looked even worse.

Re Labuan's shading, it was a compromise between making its map more distinct and the text on top of the purple background readable. It's already the darkest of the colours on my monitor; I think making it darker would compromise legibility. Of course, I could make the background shade different from the map, but I'm sure someone else will complain about that!

Anyway, there was a call to add dates of accession of the Federated and Unfederated States, so I'm considering redoing the chart when I can find the time and motivation. Cheers, cmɢʟee⎆τaʟκ 19:35, 11 February 2016 (UTC)

Huh, my apologies, you are correct. I had only checked the thumbnail and the wikipage, I hadn't clicked through. It does indeed look much much better when looking at just the actual file. I'd say that some of the text is still slightly squished, but at a personal preference level rather than a legibility one.

I see your point on the Labuan Malacca issue. I would consider differently coloured background and islands to be a unfulfilling results as well. Perhaps there's other ways, making Malacca lighter and the orange darker.

Anyway, there's nothing urgent. It's a good chart, and I like your conversion to svg, I just wish it displayed better. I'd appreciate being pinged if you ever do decide to change it, as there's a few wording changes I'd make. Regards, CMD (talk) 20:58, 11 February 2016 (UTC)

Thanks, and no need to apologise ୯ ͡°  ͜১͡° ੭

An idea I just had was to take a snapshot of a "good" rendering, write a Python/ImageMagick script to download thumbnails at every possible size within a range and diff it with the "good" image rescaled to the same size and choose the size with the smallest difference per unit area as the size shown in articles. Too much work for little gain, though!

Would you mind briefly telling me what wording changes you'd make, in case I can't find you by the time I get down to changing it, please? Ta, cmɢʟee⎆τaʟκ 22:32, 11 February 2016 (UTC)

Right, roughly:

• I'd flip the Unfederated Malay states symbol up to the top of that column with a "Collectively known as" tag, as Unfederated Malay states is a historiographical term rather than an actual entity.
• Holland->The Netherlands.
• I'd add a "the" before "Straits Settlements" in the two notes where Straits Settlements starts the note.
• "to the White Rajah Dynasty of Sarawak"->"to Englishman James Brooke, beginning the White Rajah Dynasty". Long, but there's space and is more accurate as there was no established dynasty it was ceded to but a single person.
• I'm not comfortable with the construction "annexed to", but I see its brevity, and for consistency given its multiple uses in this image it should probably also be used in the note where Labuan becomes part of the Straits Settlements, which is the only part to used "joined".
• I'd edit "Reformed as the Federation of Malaya" to "Reformed as the less centralised Federation of Malaya" for some context.
• Similar to above I'd change the brackets on Malacca and Penang to from "remained" to "reverted to" or a similar construction.
• I'd change the note on Labuan and Singapore to "Singapore and Labuan became the Crown Colony of Singapore" as Labuan was ruled from Singapore previously anyway as part of the Straits Settlements.
• I'm unfamiliar with the inclusion of "British" in the official title "Crown Colony of North Borneo" so I would suggest that "British" is removed in the 15 July 1946 instance and the 16 September 1963 instance.
• In the 1963 bit I'd shorten "as the State of Sabah" to just "as Sabah" given the others are also states.
• I'd remove completely the first Singaporean independence, North Borneo self-governence, and Sabahan independence claims. That's a misleading representation of what actually happened, and it would be far more accurate and informative to go straight from British rule to being part of Malaysia (note: the Singaporean self-government bit on the other hand is accurate).
• The use of "ceded from" in the bottom notes about Kuala Lumpur, Putrajaya, and Labuan is an unfamiliar construction to me, as ceding is an action, so it should be "ceded by" or "ceded to" (like at the top of this image). I would however keep the current formulation for concision to avoid saying who it was ceded to, and instead change "ceded" to "separated".
• Also, looking at it now, it may be worth somehow signifying with colour the expulsion of Singapore to clearly separate that note from the Federal Territory notes. Perhaps make the colour of the Singapore bar grey below that note? Just an idea.

That's what I see just going through it now. Not very brief I guess, but there you go. Regards, CMD (talk) 01:56, 12 February 2016 (UTC)

Many thanks, CMD, for the instructive and rigorous list. Hope you won't mind my copying it to the SVG's talk page so that if I don't get down to editing it, someone else can pick it up from there. Cheers, cmɢʟee⎆τaʟκ 13:15, 12 February 2016 (UTC)

Phase diagram of water

Hello. Could you make a small correction to your Phase diagram of water which appears in the article Triple point. As noticed by User:Simon Chabrillat and discussed recently at Talk:Triple point, the value of the pressure at the solid/liquid/vapor triple point has been modified from 611.73 Pa (an older value in some papers from the 1970's and 1980's) to 611.657 Pa (as in more recent papers). I have now modified the value in the rest of the article, but I cannot modify the diagram since the source file and drawing software are presumably on your computer. So could I ask you to make this small change (611.73 to 611.657) so that readers of this article will have the up-to-date value. Thanks in advance. Dirac66 (talk) 19:42, 26 February 2016 (UTC)

P.S. I now notice that you drew two versions of the diagram which require the same correction please: File:Phase diagram of water.svg and File:Phase diagram of water simplified.svg. The simplified one is not in the Triple point article, but does appear in other related articles. Dirac66 (talk) 21:07, 26 February 2016 (UTC)

Hi Dirac66, thanks for bringing it to my attention. Sure, I'll amend them tomorrow if I can find some time. By the way, File:Phase_diagram_of_water_simplified.svg was derived from the other by user:Hokanomono. Cheers, cmɢʟee⎆τaʟκ 00:27, 27 February 2016 (UTC)

SVG workshop

Cmglee, it would be just fabulous if we can work together on and off that workshop session. I have taken the liberty of putting you in as a contributor as well. I look forward to meeting and learning from you. Shyamal (talk) 02:25, 31 March 2016 (UTC)

Thanks, Shyamal – that's great news!

As you're much more familiar with Inkscape, would you know if Inkscape supports interactive and animated SVG, at very least, tooltips and hyperlinks?

Do you write SVG code directly? I do that mostly, but also write Python and Perl scripts to generate more complicated SVG, and wonder how many contributors are willing to do that.

Cheers,
cmɢʟee⎆τaʟκ 19:51, 31 March 2016 (UTC)

Inkscape itself does not support animation but there are tools to help create specific frames (as well as tools to generate intermediate frams). You can create Inkscape SVG and save as "plain SVG" which removes a lot of Inkscape specific tags so that he xml can be more easily edited by hand. I have sometimes modified SVG by hand - ex. to fix numerical values for a graph - but I have not had that much of a reason to generate pure SVG programmatically. I have on occassion used other software to generate metafiles / Postscript and then imported that into Inkscape. I think we both have ideas on feature requests for Commons-Mediawiki. I am for instance in favour of fuller support of linked images in SVG - with links to images on Commons. I believe the SVG specification supports that and it would make for very interesting annotated raster images (much better than the current rectangular blocks with popup notes) without duplication of the raster images themselves. I also have ideas (not for Wikimedia though) for tagging parts of an image SVG and be able to search SVG by shape-distance-matching (using Elliptic Fourier Analysis Coefficients) and colour-distance-searching specific parts for some applications (like a database of moth wings and the ability to search a database of carefully created SVGs using a template and additional specifications). Shyamal (talk) 04:06, 1 April 2016 (UTC)

Thanks for the detailed reply, Shyamal. It's a pity that Inkscape doesn't support dynamic SVG natively, but at least it means my investigations into doing it in pure code has not gone to waste!

My most pressing request is for bugs, especially in text and marker rendering in thumbnails to be fixed, though I don't know who best to ask, as I read that Mediawiki uses the 3rd-party library librsvg. After that, it's getting animations rendered as animated GIF; I think that's tricky because GIF animation works on keyframes but SVG elements can be individually animated.

I don't understand Elliptic Fourier Analysis Coefficients. Do you mean a visual search such as Google's Image Search where one provides a sample image and the database finds images matching it in shape and colour? If so, since Google already does it, and Wikimedia isn't averse to linking to Google (such as Maps for geo-coordinates), how about having a button in the Common search tool to upload an image? It should probably be hashed locally on the user's computer, though, to avoid overloading Wikimedia servers!

SVG already supports images embedded using Base64, and I think images linked using their URLs will work if the user views the SVG directly, but not necessarily in the rendered thumbnail. Drop me a line if you'd like me to investigate further as I've some time this weekend. Cheers, cmɢʟee⎆τaʟκ 22:34, 1 April 2016 (UTC)

Yes lots of rendering issues with libsvg as it does not seem to be in sync even with inkscape. Let's talk when we meet (hope we do, yet to apply for my visa). Shyamal (talk) 09:29, 7 April 2016 (UTC)

Looking forward to meeting you; best wishes in your visa application! cmɢʟee⎆τaʟκ 12:08, 7 April 2016 (UTC)

Our workshop is scheduled here for one hour, not sure if you got a separate slot - but I am happy to do a very rapid hands-on session for half-an-hour and then you could demonstrate some dynamic tricks (and eat into a bit of lunch). I am sure we can also work offline with the keener participants. Look forward to meeting you. Shyamal (talk) 10:01, 30 May 2016 (UTC) - PS: I see that you got a slot from 1600-1630.

Hi Shyamal, Thanks for notifying me. It seems they combined both our sessions all right but I'm ok with it – it's 1½ hours, by the way, from 10:30 to 12. You're most welcome to have more of the session if you like. Alternatively, we could have a show of hands at the beginning to split the attendees into two groups:

• Those more interested in Inkscape, and
• Those more interested in writing SVG code or scripts to automatically generate it

and have two parallel tracks (we may need to share the projector, though!) Do you know if we should prepare any slides etc beforehand? If so and you'd like my input, please let me know. See you soon, cmɢʟee⎆τaʟκ 00:04, 31 May 2016 (UTC)

I am going to be doing only in-app demonstrations. There are tons of tutorials on YouTube so I am going to concentrate on handholding and giving an overview of the handy tools that I use 90% of the time. You are certainly welcome to use some of the time to enhance the SVGs produced or to give a demo. I am going to do a rapid on-screen demo and then go to each participant interested in producing specific illustrations and help them (so that time could also be used by you) at their computer. Shyamal (talk) 05:16, 31 May 2016 (UTC)

OK, thanks. Would you be able to post on Commons (or anywhere else) some examples of the SVG you hope to produce, so that I can see how I might be able to make them dynamic? If not, no worries – I'll come up with some examples. cmɢʟee⎆τaʟκ 21:34, 31 May 2016 (UTC)

Do you think it might be possible to change layer visibility (show a specific shaded overlay) on a multilayer SVG? I was thinking something like clubbing the Venn diagram on which a mouseover would shade specific parts of the British Isles - i.e. an interactive version of Terminology_of_the_British_Isles. If that sounds like something doable and worthy, I will make a regional outline with shaded layers for each of the subsets and the venn diagram as an inset. Shyamal (talk) 12:49, 2 June 2016 (UTC)

Redrawn as interactive SVG

The original SVG is incredibly inefficient (159 KB for such a simple diagram) and so I redrew it. It now highlights regions on hover, and on SMIL-enabled browsers (not IE), clicking toggles their opacity. View its source to see how I did it :-) Cheers, cmɢʟee⎆τaʟκ 16:20, 5 June 2016 (UTC)

Awesome - it would be great to do the same highlight of regions over a map outline. Shyamal (talk) 03:39, 6 June 2016 (UTC)

I considered making a Euler diagram out of actual geographical shapes but think it wouldn't work well as the real shapes have islands and vastly different sizes. Their correct geographical placement would also complicate the diagram.

As you're much more familiar with Inkscape than I, can you create CSS style blocks with :hover set for various class or id? That, I found, is the most reliable way of adding interactivity (more than SMIL or CSS3), and a change in appearance on hover (but not click) is likely good enough for most interactive diagrams. cmɢʟee⎆τaʟκ 12:51, 7 June 2016 (UTC)

All my attempts so far have failed quite miserably - it seems that Inkscape does not quite like the handmade SVG, not sure what the issue is. When Inkscape does convert it, it seems to lose all its interactivity so I am not quite sure what is happening. Trying to see if there is an Inkscape centric way of adding interactivity (from here) Shyamal (talk) 13:12, 14 June 2016 (UTC)

It seems that Inkscape allows you to do very simple interactivity via the user-interface to specific elements (but I have not figured out all the DOM elements and properties that one can set - it works with opacity and stroke width...) - anyway I put together (a non interactive) combination of the two diagrams with layers File:British_Isles_interactive.svg Shyamal (talk) 16:23, 14 June 2016 (UTC)

Oops, I destroyed it by saving as plain svg which took away the layers - will try again and let you know. Shyamal (talk) 01:15, 15 June 2016 (UTC)

And I tried adding an event handler via Inkscape and when trying to upload it to commons I get the error- "Setting event-handler attributes onmouseover="setattribute('fill-opacity','1.0')" is not allowed in SVG files." !!! Shyamal (talk) 09:37, 15 June 2016 (UTC)

On another note, are you taking the "6 nights accommodation" package at Wikimania? If so, it seems participants are assigned one or two roommates. So that we can discuss and perhaps work on our presentation and SVG together, would you be interested to share a room? If it's agreeable, could you write me a brief consent note so I can inform WMF Events Manager Ellie Young at wikimania-accommodations@wikimedia.org please? Thanks, cmɢʟee⎆τaʟκ 18:52, 15 June 2016 (UTC)

I am on the 6 day conference and I am happy to share the room with you (I was under the impression however that there are larger dorm-like accomodations). Do you want a statement sent by email or can Ellie look at your talk page? Shyamal (talk) 03:09, 16 June 2016 (UTC)

Great, thanks. Silly me just realised that I can link Ellie to this page. I'll email her and send you a copy. Cheers, cmɢʟee⎆τaʟκ 08:58, 16 June 2016 (UTC)

Hi Shyamal, In case you're interested, I've just written a Python/ImageMagick script to convert GIF animations (especially ones of rotating objects) to interactive SVGs which the viewer can control by moving the mouse left and right. A write-up is at user:cmglee/Dynamic_SVG_for_Wikimedia_projects#GIF_animation_to_SVG_converter As I see you do a lot of illustration of birds, do you have any shareable GIF animations that I could test my script on? Thanks, cmɢʟee⎆τaʟκ 23:03, 16 June 2016 (UTC)

Nothing suitable for rotation with birds. I can however see great value in animating bird behaviours - like "flycatching" etc. Shyamal (talk) 03:47, 17 June 2016 (UTC)

Good point. Please let me know if there are any animations (especially repetitive ones) you'd like to convert. Have a good weekend, cmɢʟee⎆τaʟκ 18:32, 17 June 2016 (UTC)

Would animated PNG work (Commons does not keep the animation on resizing, resizes only the first frame - blogspot/blogger does) - File:AsiaMonthlyPrecipitation.png Shyamal (talk) 06:15, 18 June 2016 (UTC)

Good animation, but unfortunately ImageMagick doesn't support animated PNG. It's a good idea to let the reader explore graphical data that changes with time, though, so I'll see if I can make some examples.

SVG help

←This!

Cmglee, it has come to my attention that you're the person to talk to about SVGs! I need help with File:Emporia State Hornets logo.svg. This file (IMO) needs smoothed out even more mainly in the "point". It looks horrible in articles like Emporia State Hornets when it is at a smaller size. The Athletics Dept. uses a completely smooth "Power E" as it is called, and I would like to get it as smooth as possible to make it look a lot cleaner. Would you willing to help? I'm still learning about SVGs and can only crop and change the color in them! Let me know if this doesn't make since! Thanks, ☔️ Corkythehornetfan ☔️ 21:42, 20 April 2016 (UTC)

Hi Corkythehornetfan, I'll try to help! Could you please elaborate on 'smoothed out even more mainly in the "point"'? I don't really understand what you mean. Cheers, cmɢʟee⎆τaʟκ 23:30, 20 April 2016 (UTC)

Sure! The curves altogether (I think) should be smoother (cleaner), but in the middle (where it says "This!") it looks a little rough and could be smoothed out more to match the smoothness of the lines that are go up and down on the right side. (I know they're curves, so they won't be as smooth, but it's possible!) If you want an example, I can give you a link where the "Power E" is smooth [It's on an athlete's profile, but it shows what I'm asking]. ☔️ Corkythehornetfan ☔️ 00:53, 21 April 2016 (UTC)

Firstly, thanks for brining to my attention the template: Image label – I've been using the template: Annotated image but that will come in handy if I ever need an alternative.

Re the logo, I think I get it: the point doesn't end in a symmetrical 1-pixel row but is asymmetrically spread over 2 rows. If so, unfortunately there's no perfect solution. It's a phenomenon known as aliasing, when one tries to fit a continuous shape into discrete pixels, in this case made worse by the sharp point. There are 2 remedies I can think of:

1. Choose a thumbnail size at which it looks acceptable, or
2. Slightly crop or pad the image so that when it's rendered at the required thumbnail size, it looks OK.

I'd go for the former as it will reappear if someone changes the thumbnail size. You may want to attach a comment <!-- [thumbnail size set at 174px to reduce aliasing on the middle point] --> to remind editors to retain the size. Here are some examples:

200 → not smooth

199 → smoother

175 → not smooth

174 → smoother

To quickly find acceptable ones, paste http://upload.wikimedia.org/wikipedia/commons/thumb/5/5e/Emporia State Hornets logo.svg/200px-Emporia State Hornets logo.svg.png in your address bar, change 200 to your target size, and use a bookmarklet like the increment and decrement ones on http://squarefree.com/bookmarklets/misc.html to find one around the same size. It's better to err on the small side to avoid potentially overflowing a container. Good luck! cmɢʟee⎆τaʟκ 12:12, 21 April 2016 (UTC)

Alrighty, thanks! I believe all uses of the image are at 175 in the infoboxes already, so I'll go through and take your suggestions. I figured there was going to be something, and the "aliasing" is it! Thanks again, ☔️ Corkythehornetfan ☔️ 20:36, 21 April 2016 (UTC)

Table at Coin problem

Hi Cmglee,

A remark about the table you've just added to the article coin problem: I don't see the advantage of 9 columns. I suggest either reverting to 10 columns (which is unnatural in the context of the problem but convenient for people used to decimal) or going to 6 columns (since 6 is the smallest of the three numbers, and plays a special role in manually checking completion). What do you think?

Best, JBL (talk) 20:30, 13 June 2016 (UTC)

Hi Joel B. Lewis, You are right – I missed the 6-column layout as I had spotted only the single-column shift in the 10-column layout and went for the 9-column layout. I'll try to spare some time to fix it tomorrow. Go ahead and revert to 10 columns in the meantime. Cheers, cmɢʟee⎆τaʟκ 22:48, 13 June 2016 (UTC)

Thanks, Rich. I've added my thoughts on it. Cheers, cmɢʟee⎆τaʟκ 09:41, 26 June 2016 (UTC)

Integrating SVGs with MediaViewer

@Yurik: from the Foundation has worked on https://www.mediawiki.org/wiki/Extension:3d in April. There is a phabricator ticket here: https://phabricator.wikimedia.org/T3790. Yuri, Cmglee has been working on SVGs and would like to have it integrated with MediaViewer. Is this something we can include in the 3d extension? -- NKohli (WMF) (talk) 08:30, 26 June 2016 (UTC)

Thanks, NKohli and Yurik. @Rich Farmbrough: has filed a new ticket. Can you please merge them if you think they're similar enough? Thanks, cmɢʟee⎆τaʟκ 09:43, 26 June 2016 (UTC)

@NKohli (WMF): @Cmglee: I never worked on the 3D extension. I would love for it to happen, but I'm mostly involved in the graphs and Maps. --Yurik (talk) 10:21, 26 June 2016 (UTC)

I am sorry, I mistook you for being the person who worked on the extension. I see that it was @GDubuc (WMF): actually. Thank you. -- NKohli (WMF) (talk) 13:11, 26 June 2016 (UTC)

No problem :-) Cheers, cmɢʟee⎆τaʟκ 22:35, 28 June 2016 (UTC)

WikiJournal of Medicine

I've a suggestion for you. The Wikiversity Journal of Medicine accepts submissions of medically-related images for publication. The format is to give some scientific background, describe the history of any previous versions of the image, references and sources, and the decisions made for how to present the information. It's an interesting way of having a searchable (on google scholar) cite-able record. It was featured in the signpost last week too (link).

• E.g.: Häggström, Mikael (27 March 2014). "Diagram of the pathways of human steroidogenesis" (PDF). Wikiversity Journal of Medicine. 1 (1). doi:10.15347/wjm/2014.005.{{cite journal}}: CS1 maint: unflagged free DOI (link)

Your diagrams such as File:Comparison gender life expectancy CIA factbook.svg would be great candidates for submission, though you have such a massive back-catalogue, there may be others that you'd prefer! I think its an interesting experiment in bringing together the Wikipedia and Academic communities so I'm also submitting {{Eukaryote_gene_structure}}. T.Shafee(Evo﹠Evo)^talk 01:25, 1 July 2016 (UTC)

Thanks for bringing it to my attention, T.Shafee @Evolution and evolvability: I'd love to contribute to the Wikiversity Journal of Medicine, but I'm not really familiar with the medical field. Regarding data visualisation such as the life expectancy graph, I'll collaborate with you or anyone who can write meaningful analysis of the data. A few other medicine/physiology-related images might be:

• File:Sankey diagram human circulatory system.svg
• File:Human linear acceleration tolerance.svg
• File:Circulatory system SMIL.svg
• File:Animal hearing frequency range.svg
• File:Human photoreceptor distribution.svg
• File:Comparison subsaharan life expectancy.svg

Alternatively, if you or someone else could point me to a source of existing image sets e.g. higher-quality renders of animated GIFs in commons:Category:Animations_from_Anatomography, I can help convert it to interactive SVG format.

SVG workshop

Hi CMG Lee,

I was at the SVG workshop with you, and I really enjoyed the discussion. I've made two simple animated SVGs since then:

• 
  Animation of a 2-lobe Roots blower
• 
  Animation of a 3-lobe Roots blower

What I noticed, and really appreciate, is that Inkscape leaves the animation sections intact, so that if you've animated an SVG diagram, you can go to Inkscape, fix something and the animation won't need to be re-done.

I've also seen that two users have already had success with the OAuth upload feature that I was coding at Wikimania for my parliament diagram tool, which is great news.

Anyway, it was good to meet you!

Best regards, --Slashme (talk) 12:24, 3 July 2016 (UTC)

Hi Slashme,

Great meeting you too! Thanks for your kind words, and well done – especially in the accuracy in which the rotors mesh. Great news that Inkscape preserves animations. I spoke with someone from Wikimedia Germany who knew an Inkscape developer. He said he'll try to get Inkscape to support animation beyond JavaScript. There's also now a ticket to allow SVG animations in MediaViewer so users needn't click to the original file. Let's see how it goes.

After thinking about it, I'm impressed with the ability of your parliament diagram program to uniformly distribute an arbitrary number of seats in an arc. What formula do you use? I haven't managed to start on the SVG translation tool I wanted to write, but at least I uploaded my panoramas...

Have a good week,
cmɢʟee⎆τaʟκ 23:39, 3 July 2016 (UTC)

Wow, those panoramas look marvellous! Great work!

I'll be watching with interest to see what comes of that Phabricator ticket.

The spot layout works like this:

• Decide how wide the arch is in total (I think I chose the inner arc to be half the radius of the outer arc).
• Divide it up into N strips.
• Figure out how many spots can fit into each strip (this takes some trigonometry), so that you know how many spots that diagram can take
• Spread out the spots in each row proportionally.
• Sort the spot positions by angle, so that they're in a list from left to right. That way, when they're coloured from the list, the parties are arranged in wedges.

--Slashme (talk) 06:50, 4 July 2016 (UTC)

Thanks, that's a good algorithm. How is N decided? Brilliant idea to sort the spot positions by angle to group them! cmɢʟee⎆τaʟκ 12:28, 4 July 2016 (UTC)

Thanks :-] To decide N: I did this calculation for range of values of N, giving diagram sizes up to 31 thousand spots, and I included these numbers as a lookup table in my code. The program then chooses the lowest number of N which will accommodate all the seats in the given legislature. So for example, with one strip you can fit up to 3 spots in the diagram, and with two, you can fit up to 15, so a diagram with 10 spots needs two strips. I'm actually going to change the code for the smallest diagrams, though, because a diagram which is just too big for one size has a bad distribution of spots for the next size up. for example, a diagram with four or five spots looks really bad in a setup that can hold 15. My plan is to make the arch thinner in these cases. --Slashme (talk) 07:29, 5 July 2016 (UTC)

Thanks for the detailed explanation, Slashme. Nice algorithm! I just realised that the number of spots in an arch can be understood as a difference of two triangular numbers, with the number on each row incremented or decremented to get an exact amount. Cheers, cmɢʟee⎆τaʟκ 12:04, 5 July 2016 (UTC)

Just sneaked in to see the awesome (clean and elegant) animations of the rotary pumps by David! Shyamal (talk) 04:34, 6 July 2016 (UTC)

+1 :-) cmɢʟee⎆τaʟκ 12:25, 6 July 2016 (UTC)

Thank you @Shyamal: :-]. @Cmglee: can you explain the triangular number thing in more detail? Back when I did this, I had calculated the number of spots per row as follows: each row can contain ${\frac {\pi }{2asin{\frac {2}{3n+4i-2}}}}$ spots, where n is the number of rows and i is the number of the current row. If this can be expressed as a series of triangular numbers, it might make my code simpler. The script is here: https://github.com/slashme/parliamentdiagram/blob/master/newarch.py --Slashme (talk) 11:45, 6 July 2016 (UTC)

I figured that if we straightened a sector, we'd just get a triangular number, as the length of each row is proportional to the distance from the arc's centre, to equally space the spots. An arch is a sector with a smaller sector removed, hence the difference between two triangular numbers – apparently called a trapezoidal number. Example:

The first few triangular numbers are 1, 3, 6, 10, 15, 21, 28, 36, 45, 55, ... If I wanted, say, 19 spots, I could take the next larger one e.g. 21 and subtract a smaller one until it's as close as possible e.g. 21 - 3 = 18 or 21 - 1 = 20. I can then start adding/removing spots to the longest rows (which would be have smallest visual discrepancy) until I get the number I need:

o o o o o o +     o o o o o -
o o o o o         o o o o o      o = spot from first triangular number
o o o o           o o o o        x = spot subtracted from second number
o o o             o o o          + = spot then added
x x               o o            - = spot then removed
x                 x

Of course, that would make the arch too fat, so I might start with a larger one e.g. 28 and subtract 10 to give 18, and then add 1 to the longest row to get 19: o o o o o o o + o o o o o o o o o o o x x x x x x x x x x

Or 36 - 15 = 21, and then remove 1 each from the 2 longest rows to get 19: o o o o o o o - o o o o o o - o o o o o o x x x x x x x x x x x x x x x

I'd probably keep the second triangular number at least half of the first choose the first number to be around 120% of the number of seats, as it's hard to distribute spots in rows near the centre of the arc. Cheers, cmɢʟee⎆τaʟκ 12:25, 6 July 2016 (UTC)

Chinese pyramids

These aren't pyramids and the article really needs renaming - thanks for the inspiration. They are burial mounds, tumuli. Not comparable. Doug Weller talk 06:06, 11 July 2016 (UTC)

Just noting that if we used function then I think we'd include things such as cairns, long barrows, etc, most any structure in Category:Burial monuments and structures. I think we should only include structures with a pyramidal shape. Anything else strays into OR. Doug Weller talk 10:40, 11 July 2016 (UTC)

However, here's one in Korea. Tomb of the General. Doug Weller talk 10:52, 11 July 2016 (UTC)

Ok, although most of them are clearly not pryamids, Mausoleum of the First Qin Emperor is a truncated pyramid. I'll work on the article to make that clear. Sorry about that. Doug Weller talk 11:22, 11 July 2016 (UTC)

Hi Doug Weller, No problem, and thanks for looking into it :-) Re Chinese pyramids, I can't claim any expertise in pyramid architecture and in particular, the Chinese structures, so am neutral on their classification; I'll go by what the community decides.
