    edit to adjust levels

Request: This image is murky and I believe that the contrast between the hieroglyphs and the background is poor, making it difficult to see the hieroglyphs. Could you somehow make the hieroglyphs stand out more, so that the casual viewer can see the detail?? Thanks, Madman 16:09, 17 February 2007 (UTC)[reply]

Graphist opinion: This photo isn't that well exposed. I have adjusted the levels to spread out the color information over a broader range. Hope this helps.-Andrew c 18:58, 17 February 2007 (UTC)[reply]

Fabulous!! Just what I was looking for. Thank you so very much. Madman 21:43, 17 February 2007 (UTC)[reply]

Chemical structures

for images, please see the sub-page

Article(s): Various

Request: Don't hate me. Above are many simple chemical structures that would be nice to have as an SVG. They are from Category:Images which should be in SVG format. There are more in that category and Category:Chemical structures. This is a start as there are many more where this came from and when these are done, I'll try to make another list.↔NMajdan•talk•EditorReview 22:39, 17 February 2007 (UTC)[reply]

Graphist opinion: I'll start on some of these, but its a big job, so fell free to pitch in if you have the time. Maybe we should move these to a separate page, so it doesn't clog up the request page? -YK Times 03:07, 18 February 2007 (UTC)[reply]

Feel free to move them to a subpage; I'll feel less guilt about adding more. I've tried doing these myself as they are simple enough and I thought they'd be a good training tool. But I tried using Inkscape and got a weird result. I tried the first one above and it looked fine in Inkscape but when I upload it it looks like [1]. If you have any suggestions, please leave them on my talk page.↔NMajdan•talk•EditorReview 13:41, 19 February 2007 (UTC)[reply]
Okay, I moved them to a subpage, so that it clears up this request page a bit, and so that it doesn't take so long to load. -YK Times 17:25, 25 February 2007 (UTC)[reply]
It seems as though we should create some sort of library of shapes so that we can keep these consistent. ChaosNil 05:38, 19 February 2007 (UTC)[reply]
I suppose there are lots of svg's under commons:Category:Chemical compounds that you could start from. But it's probably easier to use a program that generates these. Eg. BKChem is a free one that exports svg. --Interiot 14:34, 19 February 2007 (UTC)[reply]
I notice that there are SMILES data (giving the structure of the molecule) in virtually every article. It should be possible to write a program to automatically extract the SMILES string and output an SVG... Does anyone know what WP policy is on bot-type programs that access pages but do not do any actual editing? It would probably be easier just to generate the SVGs locally and upload manually, I hope (and assuming it goes fairly slowly...). I'll start working on something of that sort, probably with MolConverter ([2]) to do the actual conversions. Time3000 16:38, 22 February 2007 (UTC)[reply]
Not sure about policy, but a good analogy to look at is your browser: it accesses pages but does not do any actual editing. I imagine any tool would be fine, so long as the output has an acceptable format and license, without annoying stuff like "This page exported by an academic version of XXX", etc. —davidh.oz.au 04:58, 24 February 2007 (UTC)[reply]
It might be best to coordinate with the editors at Wikipedia:WikiProject Chemistry (particularly Wikipedia:WikiProject Chemistry/Structure drawing workgroup), Wikipedia:WikiProject Chemicals and Wikipedia:WikiProject Pharmacology. There have been past discussions about .png vs .svg images for chemical structures, including discussions about which software produces the best results. I would recommend against any automated structure drawing based on SMILES data for anything but the most simple chemical compounds because there are many different ways to represent a single compound, with the best being a chemist's subjective preference. Also, there are literally thousands of chemical images in .png format, so it might be best to start with images on the most popular articles, rather than just the ones tagged for conversion to .svg so far.--Ed (Edgar181) 21:33, 26 February 2007 (UTC)[reply]
That sounds like a plan. Since there is a category for these structures, would anybody be opposed if I removed them all from the Move to Commons category and Convert to SVG category? They alone are creating a substantial backlog in both cats and removing all of them would help tremendously. I know that as these are converted to SVG they will be moved to the Commons so both issues will be resolved.↔NMajdan•talk 21:45, 26 February 2007 (UTC)[reply]
