The details on the diagram are what would be especially nice to be able to see clearly. -- —Hobart (talk) 21:02, 11 August 2013 (UTC)

Graphist opinion(s):

So can you tell us what those details should be, in detail, so we may recreate them?

If you can we might be able to help, but I fear I'm as lost as you seem to be, after trying to discern the details on that image. Most of it I can sort of guess if I squint, but guessing isn't good for accuracy. I come away thinking the equations and such were added more as a conceptual art element and a generalisation than anything else. Maybe that's wrong.

I assume you might have some subject knowledge that may help us.Begoon ^talk 21:15, 11 August 2013 (UTC)

RfC - Visualization of exponential function

Stale

 – DyceBot (talk) 07:00, 19 September 2013 (UTC)

• 
  Hand-drawn plots in 2D and 3D of the exponential function (real, imaginary and complex) in various perspectives, showing how they're connected.
• 
  Current image in Euler's formula, showing it as a helix in the complex space, with a sine and a cosine component.
• 
  A nicer perspective of the complex exponential helix, but lacking both detail and quality.
• 
  An better-looking (and vectorial) drawing of the same concept, that could be reused.
• 
  Animation that contains (in the final frames) a 3D visualization of how sine and cosine combine to make the complex exponential function as a 3D helix, projecting the helix into the "walls" instead of embedding the curves inside it.
• 
  Real part of the complex exponential function. The final image(s) should show how both the cosine wave and the simple (real) exponential function are intersections of this surface with the real and imaginary planes.
• 
  Imaginary part of the complex exponential function. The final image(s) should show how the sine wave is an intersection of this surface wit the imaginary plane.
• 
  Ideal quality of final image(s).

Request:

This is more of a request for comments at this point, rather than a finished request for a specific illustration. I've been trying to wrap my head around the meaning of Euler's formula, which relates the trigonometric functions to the complex exponential function. After analyzing many diagrams, most of which are in the gallery above (except the ones from here and here), I collected the insights I got into a series of sketches that I've uploaded as the first image in the gallery above. I would like these sketches to be converted into clean, high-quality images (similar in quality to the eigth image in the gallery), but I also would like to hear your thoughts about what are the best ways to visualize these relationships. Would isometric perspectives work well (as is done the animation)? Should slicing planes be drawn intersecting the 3D surface plots? Would an animation be the best approach, or a series of images, or a single image with the various perspectives, as I did in the page with the sketches? And since the complex exponential function is a 4D beast (input in the real and the complex dimensions, and output also in both dimensions), can you think of any way that it could be drawn as a single object? perhaps using 3D+color scale? Or 3D+time? Could using a non-Cartesian projection be more useful? Perhaps polar, or the Riemann sphere (which seems to provide amazing insight in this video)? Would an approach like this one be useful?

Looking forward to hear your thoughts! -- Waldir ^talk 04:16, 30 August 2013 (UTC)

Graphist opinion(s):

• just from my perspective, I recommend an animated GIF or a series of images would be the rout to take. FOX 52 (talk) 04:27, 30 August 2013 (UTC)

• I think your sketch is pretty good. At the moment, I do not see how 3D+colour or 3D+time can improve noticeably on them. Perhaps have the red lines scan over the surfaces in 3D? My feeling is also that different projections may only confuse the 'reader' ('looker'?), but you should be in a better position to decide on this. A different type of image shows how the mapping deforms a square grid, as the first image at http://www.math.ucla.edu/~mwilliams/complex.html (found in a web search). You could also have an animation, starting with a square grid and ending with its image, for instance via the route: start with square grid $x+iy$, subject the real part to the real exponential map, yielding $e^{x}+iy$, and then wrap the right half-plane around the origin, yielding $e^{x}e^{iy}=e^{x+iy}$. -- Jitse Niesen (talk) 09:46, 30 August 2013 (UTC)

  The complex map generator seems like a great tool, nice find :) However, I'm not sure I am able to get an intuitive grasp at the nature of the function by looking at it. I've searched a bit and found some more resources for visualizing exp(z) as a complex map (there are 3 animated ones here), but perhaps using the Riemann sphere would make it more obvious. The program "f(z)" seems to be able to do this, including generating animations. In fact, they talk about manipulating the 4D space in various ways to get useful visualizations, such as the "exponential horn" (a nicer version of which can be found here). I also found this animation depicting the complex exponential on the Riemann sphere, on this page – search it for "The Riemannian Self-Developing Domain", which is where the Riemann sphere stuff starts. That page also mentions that other surfaces may be more useful in some cases, and give the example of a torus (c.f the same function with a sphere). I am not sure whether the illustrations and concepts from that page will actually be useful for providing visual insight in this case. What do you think?

  Last but not least, I found a page from functions.wolfram.com which actually lists dozens of illustrations (and one animation) for the exponential function. Surely some of these ought to be useful for this discussion, right? --Waldir ^talk 15:02, 30 August 2013 (UTC)

• I think a series of images would work very well; I don't think an animation would be good, because while the images are logically connected, they're not visually connected (i.e., one doesn't transform into the next). I think your series of images mostly covers what should be included. I would suggest one notation change: Use z for a complex variable and x and y for its real and imaginary parts. I would also suggest that you include a few more graphs, bringing the entire series to:
  1. A 2d graph of $x\mapsto e^{x}$.
  2. A 2d graph superimposing $y\mapsto \operatorname {Re} e^{iy}$ and $y\mapsto \operatorname {Im} e^{iy}$.
  3. A 2d picture showing a unit circle, with an arc labeled y starting at the real axis and continuing counterclockwise, and with the endpoint being labeled $e^{iy}=(\cos y,\sin y)$. Kind of like File:Euler's formula.svg.
  4. A 3d graph of $y\mapsto e^{iy}$, done in the style of the circularly polarized light figure above (i.e., together with projections of $e^{iy}$ onto its real and imaginary parts).
  5. A 3d graph of $z\mapsto \operatorname {Re} e^{z}$, with the images of the real and imaginary axes marked so that their shapes are visible (i.e., so that the viewer can relate them to the graphs of $x\mapsto e^{x}$ and $y\mapsto \operatorname {Re} e^{iy}$.
  6. A 3d graph of $z\mapsto \operatorname {Im} e^{z}$, again with the images of the real and imaginary axes marked.
  7. A 3d graph of $z\mapsto |e^{z}|$, again with the images of the real and imaginary axes marked. (The image of the real axis will look the same, but the image of the imaginary axis will be a straight line. In fact this will be a picture of $z\mapsto e^{x}$.)
  8. A 3d plot of $x\mapsto e^{z}$; that is, it is $z\mapsto e^{z}$ with the y coordinate of the domain squashed. Equivalently, each x coordinate is sent to a circle of radius $e^{x}$.

That's a lot of pictures, of course, and it might take a long time to make them all. But I think that readers would find them useful, so if someone has the skills to both make them and make them look good, then I think the encyclopedia would benefit. Ozob (talk) 14:45, 30 August 2013 (UTC)

By the way, Waldir, Euler's formula is essentially a definition. Since exp(it) always has norm 1, it traces out the unit circle; so its x and y coordinates must be what we think of as the cosine and sine of an angle of t radians. Therefore exp(it) = cos t + i sin t. Whether or not this formula is obvious depends on what your definitions of exp, cosine, and sine are, but regardless, it has to be true on geometrical grounds. Ozob (talk) 14:57, 30 August 2013 (UTC)

Thanks for the comments. I took the liberty format your list as a numbered one so I can address the entries individually. If I understand you correctly, #1 would be something like this, #2 like this, #3 like this, #4 like this, #5 like this, #6 like this, #7 like this and #8 like this, right? (But of course, in the same style, and with the modifications you mention) --Waldir ^talk 15:37, 30 August 2013 (UTC)

• My idea for a movie:
  1. Start: shows a cosine function (actually an orthographic view from the top of the spiral of $e^{X_{I}}$).
  2. Camera pans around until its looking from the side of the spiral, showing the spiral's shape, and ending up with a sine function.
  3. Camera pans to an isometric view, and the surface of the real-valued function $e^{X_{C}}$ fades in, showing the spiral in relationship to the surface
  4. Spiral flattens to show the projection onto the real surface (curve is in contact with the surface)
  5. Real-value exponential function is drawn onto the surface as a curve starting from zero and growing in the negative and positive directions at once.
  6. Surface fades away, camera pans to the view at the bottom of the pen sketch
  7. A few circles at $Ae^{i\psi }$ are drawn in, one by one, for different values of A.
  8. The trumpet-shaped surface fades in.

The question is, what tool would do this best? Blender3D? Mathematica? R? D3.js? --Slashme (talk) 08:19, 1 September 2013 (UTC)

That's a great idea! I can see most of it playing in my head as you describe it, but I have few issues: first, I am not sure step #3 would work well, because the spiral has both a real and an imaginary component, and the real-valued surface, well, only contains the real part of the function. What can be seen in that surface is the cosine and the regular exponential curve, as the sketch drawing shows. Trying to include the spiral in that diagram would break the definition of the three axes, which is: one for the real part of the argument, one for the imaginary part of the argument, and the vertical component for the real part of the function. There's no room for the spiral's imaginary component short of making this a 4D plot. It might be possible with some trickery, but I'm not sure that would make it clear.

Another issue is in steps #6 to #8, and it's kind of the same problem: for the trumpet-shaped surface, the axes would have to change: this time we have two dimensions (real and imaginary) of the output, and one of the input (real), and by panning the camera in a continuous motion we'd be reinforcing that the meaning of the axes say the same, while actually the frame of reference would change. That may not be intuitive, or worse, it might induce incorrect intuitions.

Perhaps if we faded the surface away *and* the axis being replaced ($X_{I}$ in the drawing), then drew the new axis (essentially the same thing but with a new label, "Im{$e^{X_{C}}$}" – or "Im{$z$}" as Ozob suggested above), the transition would be clearer.

Finally, I would add in the end a transition between the trumpet and the spiral, using the same axis-replacement technique: fade out simultaneously the exponential curve, the trumpet surface (and circles if they're still present, but they should have faded out by now), and the "$X_{R}$" axis, leaving only a circle at zero with radius one; and this time, instead of fading in the new axis ("$X_{I}$", or $y$, per Ozob) all at once, it could expand from the center, making the circle spread out, like a spring, into the spiral. Then it could even loop back to the beginning!

For now I'm mostly focusing on my concerns regarding your proposal, but I do think it has a lot of potential, so we probably should polish it, iron it out and move forward with it. Let me know what you think. --Waldir ^talk 12:45, 1 September 2013 (UTC)

ps - I'm pretty sure that if this can be done with D3.js, it should. That would make it possible to have an interactive version (hosted elsewhere, I suppose) where people could, for instance, advance the animation at their own pace.

Some good points here, Waldir. I guess we'll need some scene changes: can't do it all in one take and remain mathematically honest. I've been looking at the R rgl package, and I think it would be able to do it relatively well, but I've also been meaning to learn D3.js, and you're right: it has more interactivity options. Let me see how long it takes to get some kind of visualisation of any part of this running on D3.js, and then I'll put up a repository for us to start hacking. --Slashme (talk) 18:21, 1 September 2013 (UTC)

Replying to myself here: I just did some reading, and D3.js is not great for drawing functions, so I'm first going to look at rgl. --Slashme (talk) 19:10, 1 September 2013 (UTC)

I've started working on this, and so I've created a github repository to store my work. Anyone who wants to contribute, help, etc, is welcome. I'm a bit of a noob on github, so if I'm doing anything wrong, or less efficiently than I should, please advise! At the moment, all I've done is to figure out how to generate the basic surface: still need to add axes, set the scene properly, add lines and stuff, but it all looks quite feasible. --Slashme (talk) 21:30, 1 September 2013 (UTC)

How about MathBox? To see its potential, see the introduction post (there's even a bit about visualizing the complex exponential — visualization included) and this presentation made using it. --Waldir ^talk 17:27, 2 September 2013 (UTC)

Here's a first test using MapBox. Seems to be a quite fast way to make nice plots and animations! --Waldir ^talk 03:25, 3 September 2013 (UTC)

That looks really cool! --Slashme (talk) 18:54, 3 September 2013 (UTC)

Hmm, any chance you could upload a screenshot of what you see? I'm getting quite some variation in results using different computers. In some, the surface doesn't appear, in others it's the curves, and in most the surface shading is a little off. --Waldir ^talk 17:18, 4 September 2013 (UTC)

Graphist opinion(s):

 Question: So I'm wondering... Provided it can be done legibly and clearly, might it be worth considering overlaying this onto a "knocked back" (faint, ghosted) image of the art itself, like the one used already in the article - File:CAPPELLA SISTINA.jpg, plus extant images for the "Ancestors" window "arcs" which don't appear in that, I think..? With white-out text and translucent coloured panels it might just work... I guess if it's done to scale in proportion with that we could maybe look at it both ways pretty easily... Begoon ^talk 13:31, 27 August 2013 (UTC)

 Request taken. I'll take this either way - I'll work on the diagram first to that scale, then at least we'll have that even if my other idea doesn't pan out properly - no work wasted that way. I'll start tomorrow, give me a couple of days to fit it in. Begoon ^talk 13:50, 27 August 2013 (UTC)

The "knocked back" image sounds like a great idea. Doing both versions (basic plan + overlay) would be preferable. thanks! -- Hazhk ^{Talk to me} 13:59, 27 August 2013 (UTC)

Well it works for me as a plan of work, the basic 'plan' will be a layer which can be separated. As I say, give me a couple of days - it's worth taking a little longer to try to do something "nice" for this one, I think. Cheers. Begoon ^talk 14:04, 27 August 2013 (UTC)

Update: Just a note that I am working on this - because I'm drawing it to scale to match the bitmap image it's taking a while. I'll upload the basic line diagram with text first for you when I get to that point, probably tomorrow. The overlaid version I think will be good from the experiments I've done - that version will follow. Begoon ^talk 04:58, 30 August 2013 (UTC)

Take as long as you need! Thanks. -- Hazhk ^{Talk to me} 15:40, 30 August 2013 (UTC)

• Ok, here's the svg diagram: File:Sistine Chapel ceiling diagram.svg. It's to scale, to match the photograph bitmap. The lettering is 85% black in that, because just black felt a bit "harsh" - but you can revert to the penultimate version if you want the type "blacker". I toyed with the idea of centering the type in each of the descriptions across the middle section, but got one of those "can't decide" moments and left it all left-justified. It can be changed.
• I also uploaded a composite overlaid png as an idea of what I'm doing: File:Sistine Chapel ceiling diagram overlay composite.png. That's not the final quality, and it's not finished, because I still have to add the "Ancestors" bitmaps behind the blue arches, relocate the "arches" outside the main rectangle, and tweak a few other things, including trying to make the lettering a bit more legible at smaller sizes without covering all the artwork - but it can give you a look at what I'm doing with it.

For some reason, Commons is screwing up the thumbnails on that one - but you can see it full size at: User:Begoon/sandbox/Sistine Chapel composite - use your browser to zoom on that until the Commons thumbnailing settles down. Cheers. Begoon ^talk 12:55, 31 August 2013 (UTC)

Looks good so far. I agree that black looked too harsh on the first image; the background colours are very pale and the 'washed out' text looks better. The second file is exactly as I imagined when you described it. Once the additional backdrops are added it should be ready to use! Thanks again. -- Hazhk ^{Talk to me} 14:36, 31 August 2013 (UTC)

Great. Well, the plain diagram is an improvement in the article for now, I think. I'll take some time to see how I can improve the overlay version while I finish it. I think somewhat bigger type is going to be necessary, without obscuring too much of the masterpiece, and I may even (ever so judiciously) lose a few words from a couple of the more wordy descriptions, but we'll see how it goes.

Ok, comments welcome on the latest version of File:Sistine Chapel ceiling diagram overlay composite.png (again, use User:Begoon/sandbox/Sistine Chapel composite and "browser zoom" if Commons thumbnailing is lagging).

• Major caveat is that, because all of the "Ancestors arches" images available at Commons had differing cropped areas available, I have had to scale them to differing sizes as backdrops. Particularly noticeable on "Aminabad", but applies to most of them. If we can find available consistently sized images I could recrop and rescale them - but perhaps it's not the end of the world, as it is a "schematic" and they are behind the tinted panels, so they're indicative rather than accurate. Shame, though, because the central part is to scale.

Anyway, all comments welcome - if you think "I wish it "x..."" then please ask, as whatever "x" is may be possible, and if not, I can easily say so . Cheers. Begoon ^talk 12:45, 3 September 2013 (UTC)

I think the diagram looks really good. I also prefer the text aligned to the centre. Good spot with the "sun and plants" :)! I can't think of any improvements that could be made right now... The arches look fine. thanks very much - it was worth the wait! Hazhk ^{Talk to me} 15:31, 3 September 2013 (UTC)

Yeah, it took a while... Been busy in real life too. I centered the type on the "plain" svg too, now.

Just a suggestion - in the "gallery" article, the "main" image is 900px, and this one might benefit from a little additional width just for some legibility - I took the liberty of increasing it to match, but feel very free to revert me if that's too much. Begoon ^talk 16:05, 3 September 2013 (UTC)

Usually in the web pages it's a red logo on a white rectangle, but there's also an example where it's a white logo on a red rectangle. This page: http://www.abf.se/Press-Nyheter/logotyper/ uses the (google translated) phrase "with a distinctive vertical bar."

That page also says: "The logo may not be manipulated or cropped.", and "Contact ABF if you have any questions regarding usage."

Are we confident that it is a faithful representation to omit the background bar, or would it not be preferable to use one of the uncropped versions? This is confused further by the fact that the eps files downloadable do contain versions with it in the top half of the rectangle, and just the oval, but I wonder if the oval is actually intended to be used, cropped, alone, or is just provided for designers' convenience, having read the site? Perhaps we should do what they say, and ask - but I'd feel safer with the bar included, either red or white, in the meantime. Comments welcome. Begoon ^talk 04:52, 3 September 2013 (UTC)

I think that's technically not necessary since we want just the basic text, and shape. Best to avoid Threshold of originality and keep it in the free column. There usage rule continues to say"on all printed material" I don't even know if that would apply here. FOX 52 (talk) 13:53, 3 September 2013 (UTC)

Why do "we want" that, and who is "we"? There's no threshold of originality problem with a coloured rectangle that I'm aware of. As far as I'm concerned we should represent a company logo (or any other copyrighted image) as faithfully as we can. Have you read this: Wikipedia:Graphics Lab/Resources/Illustration Advice, in particular

• The vector versions of non-free images like company logos and other items need careful handling. Graphists at the lab cannot always convert a raster file (JPEG, GIF or PNG) to vector (SVG) because a manual re-draw of the logo is likely to result in an inaccurate version of the logo and may look like a cheap imitation! Thus, searching for an official version of the vector image is very important.?

Just because copyright laws arguably allow us to create unfaithful versions does not mean we should do so, just because we want to. And I'm entirely unclear on why we would want to, especially when it has no effect whatsoever on whether we treat it as copyright exempt under TOO or not. Companies and organisations carefully create and design their logos - they don't do that so that we can misrepresent them without a care. That's not fair to the company or organisation, even if we can argue it is legal. And it's unnecessary.

You are a good, accurate graphist. I would have thought it would be important to you that we represent a design in exactly the way the designer and owner intended? Begoon ^talk 14:38, 3 September 2013 (UTC)

I uploaded 4 versions which are just conversions to svg from the zip of eps files downloadable from the website - see above. You should be able to use any one of those as a faithful logo - if it's not in an infobox then the red background ones show the vertical bar better obviously. (or, of course, File:ABF logo w t.svg on a white background will "cheat" and seem to be just the oval and letters - but that's not what I'd do )

I'd probably use File:ABF logo r t.svg () in the article for visual choice, I guess. Just call me a fussy old pedant who likes to respect designers. Begoon ^talk 12:03, 4 September 2013 (UTC)

Barnstars for Wiki Loves Monuments helpers from the UK

Request:

Note: this is a re-posting of a request originally made on the Commons Graphics Lab two weeks ago (where there has been no graphist response).

Several volunteers have given significant amounts of to help prepare for the UK's first contribution to the Wiki Loves Monuments competition, and we would like to be able to award some barnstars. I could probably make my own by plonking the WLM logo on top of a standard barnstar, but I wondered if a graphist might be able to do something more professional :) The barnstars would in any event need to look a bit different from the logo above, which is used to indicate one of the winning images in the competition. If it's difficult to incorporate the WLM logo into something new, perhaps something with a camera theme would work, as it is a photographic competition. A UK theme is not essential.

If possible, I'd like two, please, a standard WLM barnstar and a gold WLM barnstar. Thanks for any help you can give. --MichaelMaggs (talk) 11:06, 11 September 2013 (UTC)

I would like a graphic that shows F in context of other atoms neighboring it. The problem is our graphic of the table is so tiny and the screen is not as good as paper when you want to zoom subconsciously (sans click).

What I want: a "torn out" section of the periodic table (rough edges). Make the tear so N, O, F, Ne, and Cl, Br, I are shown (these are really the relevant neighbors). Use our creativity and judgment on the exact graphics. Here is a potential table, but others exist: http://www.bpc.edu/mathscience/chemistry/images/periodic_table_of_elements.jpg

I suggest coloring F by its color code for structure drawings (sort of a yellow, can look it up). Leave the other atoms plain.

Caption will be something like "Fluorine, shown with significant periodic table row and column neighbors."

Would anyone happen to be able to remove the artefacts from the file for me? Fry1989 ^eh? 21:58, 24 September 2013 (UTC)

Graphist opinion(s): It looks like when you changed the math code to adjusting the arms, you received the hash marks. The file may have some corrupt inputs. I've made two attempts, but is doesn't look like it's working. FOX 52 (talk) 16:06, 25 September 2013 (UTC)

Yeah - looks to me like rsvg doesn't like it when it makes the png thumbnails. Inkscape renders it fine, as does Google Chrome. It's fine here too: standard of Sweden.svg viewed as an svg, but the artefacts appear when thumbnailing. You get these weird rsvg artefacts sometimes, and they can be hellish to track down. I have to confess I often just go back to an earlier version without the problem and remake the alterations subsequent to that differently. Some of the true gurus may know - there was a US map that went haywire like this recently - took ages to fix, and I can't remember who cracked it - I'd have to look it up...Begoon ^talk 16:22, 25 September 2013 (UTC)

Actually, something odd is going on with this - some of the thumbnails look like very blurry bitmaps to me right now, rather than vectors. Not sure why. Odd. Try this, for example: standard of Sweden.svg/500px-Royal standard of Sweden.svg.png - or maybe you won't see what I see due to caching...Begoon ^talk 16:43, 25 September 2013 (UTC)

I still standard of Sweden.svg/500px-Royal standard of Sweden.svg.png see the marks, and on my attempts I redrew the flag, cross, and white box that hold the emblem - but no such luck maybe it could be uploaded as a new file. FOX 52 (talk) 18:09, 25 September 2013 (UTC)

Tried that already a while ago . File:Sweden Royal flag grand coa 2.svg. No joy. rsvg doesn't like something about that file. I tried "scour" and "plain" in Inkscape. There are validation errors on the file at W3C, but I can't fix it with any "simple" tricks. As an svg it always seems to look fine, but the png thumbnails are screwed. I'm probably missing something stunningly obvious, but it's late here... Oh, and yeah - forgot to say - I also see the artefacts at your link, but on a blurry thumbnail enlarged - that's why I'm blaming rsvg. Begoon ^talk 18:22, 25 September 2013 (UTC)

 Request taken by FOX 52 (talk) 02:24, 25 September 2013 (UTC).

I really don't understand why this is happening. All I did was take the two SVGs (flag and CoA), and shrank the CoA to fit properly in the box. It worked fine with File:Sweden-Royal-flag-lesser-coa.svg and several other flags I've done this way. Fry1989 ^eh? 18:52, 25 September 2013 (UTC)

It's not going to be your "fault" Fry. My money is on it being a strange anomaly with the way rsvg renders png thumbnails sometimes - and you can't predict that. It's relatively rare, but happens, and it's a bit of a random software thing which I've experienced a few times. The svgs seem pretty fine, albeit with a few validation errors - but Inkscape and my browser don't care about them, and neither does wiki, viewed as svg. But the wiki rendering to png thumbnails is screwed, and that's rsvg. If you do it again, with the inevitable slightly different steps that would entail, it might not even recur - though no promises with "spookiness". Unless, as I said, I'm missing something obvious. A true guru may come along any minute and make all my speculation look silly...(or not...)Begoon ^talk 19:01, 25 September 2013 (UTC)

Looks good on my end. - So what did Perumalism do?

• There may be compatibility problems between the Wikipedia / Media rendering engine and Inkscape:

• Select everything (Ctrl-A) and choose the Path>Object to Path command.
• Select everything (Ctrl-A) and choose the Path>Stroke to Path command.
• In the File>Save As.. dialog look for the drop-down menu just above the Save button and save as a Plain SVG.

This is what I did Perumalism Chat 05:30, 26 September 2013 (UTC)

Well you fixed it. I missed the steps of Path - Object to Path, and Path - Stroke to Path, which I should have remembered, as I've had to do it before - so I just tried the plain svg. Well done - it was a rendering rsvg problem, and that was the "simple" fix I failed to find or remember. Begoon ^talk 06:50, 26 September 2013 (UTC)
