Angle images
Hi! Image:Angle obtuse acute straight.svg seems to be a modification of Image:Angle acute obtuse straight.png, which is licensed under GFDL, and so the source and author of the original should be given in the licensing information of the modification. Your image clearly contains work of your own, but clearly it also appears as a modification. This goes for both the en: version and the copy at commons. --Eddi (Talk) 05:22, 18 March 2006 (UTC)
 * Done, but I would say that creating a new version of a simple bitmapped illustration (such as this) in a vector format and providing its source is more than just a modification. It's more "inspired by&hellip;" than "a modification of&hellip;". –Gustavb 10:23, 18 March 2006 (UTC)

Request
Hi Gustavb,

My name is Fernanda Viégas and I have been studying Wikipedia for a while now (you can see a paper I published on the subject here). I would like to ask you a few questions about your activities as a Wikipedia image creator. I am fascinated by the pictorial side of Wikipedia and it would be great to hear about this community from one of its members. Would you be available to participate an email survey this week? Thanks, &mdash; Fernanda 03:49, 4 April 2006 (UTC)  | talk

A question, a request and an offer :)
Hi Gustav,

a while ago I was going to write you to highlight that in your exploded PC image the mainboard was on the wrong side. I thought you had corrected the problem when seeing your new versions, but I have now noticed that you have *kept* the old ones. There have really been personal computers that had the mainboard on the "left" side? Ok, so far with the question :) The request is to realize a similar image for the laptop article. That would be great. In exchange, I offer to validate both the PC and the laptop version(s) as SVG 1.1. I'm really bad at graphics, so the only thing I can do here is to fiddle a bit with the code.

Sincerely, Gennaro Prota &thinsp;(talk) 13:44, 9 May 2006 (UTC)
 * Thanks for your input&hellip;
 * Regarding your question, this issue has been discussed over here: Featured_picture_candidates/Personal_computer where I also state my view. The older versions 1, 2 and 3 are not as good as 4 and 5 (and shouldn't be used), but I guess that they still should be kept for the FPC archive.


 * I agree with you that the laptop article could benefit from a similar illustration. Unfortunately I'm quite busy right now and therefore doing such an image could take some time (probably more than a month with my current schedule)&hellip; I'll think it over during the week and make up my mind.


 * Oh, and I just assumed that the output from Inkscape (which I use) was valid SVG, but after trying it with Batik's validator I realize it's not. Adding a DOCTYPE and some attributes in the  -element fixed it. So even better than fixing my svgs would be to attack the source of the problem and fix Inkscape (or at least make the developers aware of the problem)&hellip; :) Thanks for your offer!


 * Speaking of SVG and coding, something I liked to have for a long time is an SVG optimizer. My SVGs are filled with stuff like style="stroke:none; stroke-width:5; stroke-color:black..." (the stroke-* are redundant) and x="15.0000000000" (the zeroes could be trimmed). Are you aware of any open software that can do this? An optimization script would be much appreciated by me (and probably by other SVG contributors on Wikipedia).


 * –Gustavb 13:31, 10 May 2006 (UTC)


 * Hi, well, first of all thanks to *you*. I understand that such images may require really a lot of time, so don't feel any pressure for the laptop one, of course. Yes, I agree that Inkspace's output (which I use too) should be standard compliant. Since, for human kind sake, I do veery little graphics stuff (I think a well-trained goat would draw better than me :)) I usually optimize them by hand. Of course that's not a very handy approach if you have a lot of images to fix. Anyway, you can use an inline style sheet as the one I've used for the tupperware image (http://upload.wikimedia.org/wikipedia/en/9/9b/Tupperware_Brands_Corporation_logo.svg): there you can specify a class:

 <![CDATA[ .c1 {fill:#2A2522} ]]>


 * and refer to that later. In the tupperware image I &lt;g&gt;roup all the elements and specify c1 as class for the whole group:




 * Another size optimization is reusing elements; you can see that I reuse the 'p' image, for instance: the two 'p' characters in the logo are identical, just (obviously) placed in different positions, so one can be obtained by translating the other (this is done by defining new entities: see  etc.). I guess programs to do these sorts of things exist though, I just don't know about them. -- Gennaro Prota &thinsp;(talk)  14:22, 10 May 2006 (UTC)

Hook 'em hand
Hello Gustavb! I recently saw your fine handy work featured on the front page, the vectorization of J.J.'s pirate image. I am currently working on an image of my own Image:Hookem hand.gif, which I believe would benefit from vectorization. I am a little unclear about what it may entail. In short, the problem I hope to solve is that the gif image becomes distorted when it is used in its many different applications, including Template:User longhorn or Template:UTexas-stub. Its use in hundreds of articles makes it imperative that it appears properly in every instance. Is vectorization the proper fix for this? Is vectorization something that I could do on my own with a free software tool? If not, is there a noticeboard or group on Wikipedia that offers vectorization assistance? Thank you so much!! &mdash; Scm83x hook 'em 22:13, 12 July 2006 (UTC)


 * Hi! It's hard to draw icons that look good at different sizes. Here is a blog post that explains some of the problems. In this case, however, I think your image would benefit from a vectorization. I use Inkscape for vectorizing (it's open source freeware) and I usually do it by redrawing the image by hand. You can even do it automatically by using tracing (this is also possible in Inkscape), but in general I think the quality of the result gets too low. I'm not sure if there's any group that offers vectorization on Wikipedia, but I'm willing to help you with that if you like&hellip; –Gustavb 11:40, 14 July 2006 (UTC)


 * I downloaded Inkscape, and I don't think I'm very good at it thus far. I have a version of the file with the border only 1px thick if that helps.  I also have a version at 100px by 100px.  I will start messing with tracing for the moment.  I don't want to tkae a lot of your time by asking you to vectorize this, but if you could help, I (and the entire UT community of Wikipedia) would appreciate it. &mdash; Scm83x hook 'em 11:45, 14 July 2006 (UTC)


 * No problem &mdash; here is my version. – Gustavb 16:20, 15 July 2006 (UTC)

Howto
I'm trying to create an SVG-file form the following tex

%&latex \documentclass{article} \usepackage[matrix,arrow,ps]{xy} \pagestyle{empty}

\begin{document} \[ \xymatrix{ A \otimes A \otimes A \ar[r]^{\mu_A \otimes \mathrm{id}_A} \ar[d]_{\mathrm{id}_A \otimes \mu_A} & A \otimes A \ar[d]^{mu_A} \\ A \otimes A \ar[r]^{\mu_A} & A } \] \end{document}

Could you tell me how to do this? Markus Schmaus 12:53, 28 July 2006 (UTC)


 * The best (free) way of converting PS to SVG that I know of is by using the ps2svg.sh script. It requires that you have pstoedit, skencil and ghostscript installed. To use it for latex you can do it like this:

> latex file.tex > dvips -E file.dvi -o file.ps > ./ps2svg.sh file.ps
 * The result is not always perfect so it might require some editing, I would recommend Inkscape for that. Just tell me if you would like some help with the converting&hellip; –Gustavb 15:37, 28 July 2006 (UTC)

dragonfly
I was wondering if you could help me with Featured picture candidates/Dragonfly morphology. I tried to edit your SVG in illustrator to make the hind wing wider at the base to be more accurate. However, when I saved the file a) all the strokes got about 4 times as thick and b) the file size went up tenfold. Any ideas what I did wrong, or what I could do to correct this?--Andrew c 03:51, 7 October 2006 (UTC)


 * As far as I can see, the huge file size is caused by an outlined embedded version of the Arial font included in the file. I'm not familiar with Illustrator, but I'm sure there is some setting to prevent it from embedding the whole font. As for the strokes my guess is that Illustrator forgets to update the stroke-widths when it changes the viewbox (this is likely a bug). I've merged your changes in to the original SVG and uploaded it over your file&hellip; is it ok? –Gustavb 11:12, 7 October 2006 (UTC)


 * Ah, ok. Thanks a lot! It looks like the wing needs some more adjustment, so could you tell me how you "merged [my] changes into the original SVG", so I don't have to always come to you to fix the files that illustrator breaks. Much apprecaited!--Andrew c 13:15, 7 October 2006 (UTC)


 * I just opened the two files in Inkscape (which I used to create the original SVG), and copied the changed paths from your file and pasted them in my file and changed the strokes. I think it will be easiest for you if you make the changes with Inkscape directly (you can download it here if you don't have it already), the path editing is a bit different from Illustrator, but it's fairly easy to learn. To reduce the file size you can save the file as "Plain SVG" instead of "Inkscape SVG". Thanks for your work! –Gustavb 16:53, 7 October 2006 (UTC)

Angle
Wow, big improvement :-) The images have helped a lot. The only other section that really needs illustrations is "A formal definition". The first subsection ("Using trigonometric functions") could do with a triangle with x, y, &theta;, sin&theta;, and cos&theta; marked... I'm sure there must be an exsisting image that's suitable. Not sure about the other sub-section ("Using rotations") though.

There's nothing to stop you (re-)grading maths articles - anyone can do it... see WikiProject_Mathematics/Wikipedia_1.0 for info. Just make sure you copy across your grading/comments to the geometry sub-page. There's still a fair number of ungraded articles should you wish to get involved.

Fair use rationale for Image:Kth_logo.svg
Thanks for uploading or contributing to Image:Kth_logo.svg. I notice the image page specifies that the image is being used under fair use but there is no explanation or rationale as to why its use in Wikipedia articles constitutes fair use. In addition to the boilerplate fair use template, you must also write out on the image description page a specific explanation or rationale for why using this image in each article is consistent with fair use. Suggestions on how to do so can be found here.

Please go to the image description page and edit it to include a fair use rationale. Using one of the templates at Fair use rationale guideline is an easy way to ensure that your image is in compliance with Wikipedia policy, but remember that you must complete the template. Do not simply insert a blank template on an image page.

If you have uploaded other fair use media, consider checking that you have specified the fair use rationale on those pages too. You can find a list of 'image' pages you have edited by clicking on the "my contributions" link (it is located at the very top of any Wikipedia page when you are logged in), and then selecting "Image" from the dropdown box. Note that any non-free media lacking such an explanation will be deleted one week after they have been uploaded, as described on criteria for speedy deletion.

Notification: changes to "Mark my edits as minor by default" preference
Hello there. This is an automated message to tell you about the gradual phasing out of the preference entitled "Mark all edits minor by default", which you currently have (or very recently had) enabled.

On 13 March 2011, this preference was hidden from the user preferences screen as part of efforts to prevent its accidental misuse (consensus discussion). This had the effect of locking users in to their existing preference, which, in your case, was. To complete the process, your preference will automatically be changed to  in the next few days. This does not require any intervention on your part and you will still be able to manually mark your edits as being minor in the usual way.

For established users such as yourself there is a workaround available involving custom JavaScript. With the script in place, you can continue with this functionality indefinitely (its use is governed by WP:MINOR). If you have any problems, feel free to drop me a note.

Thank you for your understanding and happy editing :) Editing on behalf of User:Jarry1250, LivingBot (talk) 19:26, 15 March 2011 (UTC)

A request for you to correct an image you helped with before
The dragonfly image you helped to alter turns out to have been drawn with Honeybee wings! The Tumblr community had this brought to their attention recently by an entomologist's posting: http://quietmagpie.tumblr.com and would like to ask your help in getting it changed. You can probably tell I am not familiar with adding anything to Wikipedia, so I hope everyone takes that into account. I hope you can contact that entomologist to see what they would need to get it corrected. I also put something on the page for Andrew_c so he can alter the image to the correct one. https://en.wikipedia.org/wiki/User:Andrew_c Hyperbole6000X (talk) 12:06, 10 January 2016 (UTC)

Image copyright problem with File:Gustavb.jpg
Thank you for uploading File:Gustavb.jpg.

This image is a derivative work, containing an "image within an image". Examples of such images would include a photograph of a sculpture, a scan of a magazine cover, or a screenshot of a computer game or movie. In each of these cases, the rights of the creator of the original image must be considered, as well as those of the creator of the derivative work.

While the image description page states the source and copyright status of the derivative work, it only names the creator of the original work without specifying the status of their copyright over the work.

Wikipedia takes copyright very seriously. It may be deleted soon, unless we can determine the license and the source of the original image. If you know this information, then you can add a copyright tag to the image description page.

If you have uploaded other derivative works, consider checking that you have specified their license and tagged them, too. You can find a list of files you have created in [ your upload log].

If you have any questions, please feel free to ask them at the media copyright questions page. Thanks again for your cooperation. Kelly hi! 16:35, 22 May 2018 (UTC)

Euclid I.32 diagram
Hi Gustavb! I'm a philosopher working on a an article about explanatory proofs (soon to be published, if all goes well, in the journal Philosophy Compass). I was happy to find your beautiful diagram for the proof of the Butterfly Theorem, which I discuss in the paper. I'm planning to use the diagram, if that's all right with you.

Could I possibly convince you to make another diagram in a similar style for the paper, so that I can maintain visual uniformity? The diagram would be for the proof of Proposition I.32 from Euclid's Elements (the theorem that a triangle's interior angles sum to 180 degrees). It's a much simpler diagram than the Butterfly one, so hopefully it shouldn't cause you much pain! I've got a Geogebra version of the diagram which I can send you to show the labeling. I'd appreciate it most extremely.
