SVG range map?[edit]

I'm not a graphic artist, so I'm hoping someone might be able to help with this. The map in File:Tachybaptus ruficollis-map-distribution.svg isn't fit to the image size, but whenever I try to resize the page it gives me an error message. Could somebody take a look at it? Much appreciated, Focus (talk) 23:14, 29 September 2010 (UTC)

Adjusted "viewBox" in text editor... AnonMoos (talk) 16:30, 2 October 2010 (UTC)

Image restoration[edit]

I'm wondering if anyone is willing to do some restoration on this photograph? I'm not a expert at fixing images in a poor condition and also don't have much free time ATM. Bidgee (talk) 15:43, 2 October 2010 (UTC)

Photography workshop? You might get better response there. ZooFari 05:47, 3 October 2010 (UTC)

Failed to upload picture[edit]

I have tried to upload this image from Flickr: http://www.flickr.com/photos/dahlstroms/4681829897/ . However when I try to use Magnus Manske's bot (http://toolserver.org/~magnus/flickr2commons.php) it gives a message saying the file was uploaded although it wasn't. And when I download the picture from Flickr and try to upload it manually, there is an error message saying "This file contains HTML or script code that may be erroneously interpreted by a web browser." I've tried both the original version and a cropped version. Thank you. Athyllis (talk) 15:10, 9 October 2010 (UTC)

I think this has to do with HTML code in the EXIF data of the image. You might need an EXIF editor to remove the code. Please see this discussion for a similar case. -- Orionisttalk 23:05, 9 October 2010 (UTC)
Thank you. I could remove the code with GeoSetter as suggested in that thread. Athyllis (talk) 09:59, 10 October 2010 (UTC)

I think there is something odd about this .pdf file[edit]

I think there is something odd about File:DIA_Af-Pak_wanted_posters,_October_2006.pdf. It is over 3 megabytes, and contains perfect detail, when viewed within adobe reader. But there is something within the file that makes it render illegible small.

I'd appreciate advice about how to remove whatever makes the images render small.

Thanks! Geo Swan (talk) 00:56, 25 October 2010 (UTC)

In the PDF file, the images are presumably indicated as only occupying a relatively small area of each page's total size, and the thumbnail view is merely reflecting this. How to fix it depends on what your goals are and what tools you have available. You could disembed the images with a program like pdfimages in the xpdf package and upload them separately as JPEGs (not as a single PDF)... AnonMoos (talk) 06:58, 25 October 2010 (UTC)
The pdf is 40 pages long, with two pages devoted to each individual. The first page consists solely of an image and a name. The second claim contains some biographical details, a classification, and some allegations.
Page 30 contains a mini-bio of an individual claimed to be a former Guantanamo captive. Unfortunately the documents the DoD has published about this individual raise doubts as to his identity.
I tried using the inkscape program to cut page 30 from the larger file. Unfortunately it too renders tiny. I'd like to be able to use http://commons.wikimedia.org/w/index.php?title=File%3ADIA_Af-Pak_wanted_posters%2C_October_2006.pdf&page=30 as the URL in a {{cite}} template, where the reader could see that page with a legible resolution.
Contrast this with File:The Wire Issue37v11.pdf -- commons renders these pages full size. -- 16:08, 25 October 2010 User:Geo Swan
OK, extracting page 30 is easy (it was the idea of fixing the whole PDF which was rather daunting). See File:DIA Af-Pak wanted posters October 2006-Page30.pdf... AnonMoos (talk) 12:58, 26 October 2010 (UTC)
That is terrific! Thanks! Did you use inkscape? Geo Swan (talk) 02:10, 1 November 2010 (UTC)
No, I used "xpdf" utilities (decompiling) and Ghostscript (recompiling). I don't actually use Inkscape to edit files (only to test and convert SVG files). AnonMoos (talk) 05:01, 1 November 2010 (UTC)

How to make a locator map?[edit]

How to make a locator map of e.g. Great Britain? I know how to edit svg-files (I have an intermediate knowledge of Gimp and Inkscape). Is there a tutorial anywhere to be found? Citypeek (talk) 09:44, 31 October 2010 (UTC)

Not sure what you're asking -- a map indicating the location of GB in Europe or the world, or a series of maps of GB with a red dot indicating the location of a particular town, or blank map of GB on which a red dot can be placed interactively by sotware... AnonMoos (talk) 12:52, 31 October 2010 (UTC)
Like this picture: India -- 13:43, 31 October 2010 User:Citypeek'
There's Category:Blank maps of the United Kingdom... AnonMoos (talk) 14:20, 31 October 2010 (UTC)
Thank you, but you miss my point. I want to know how to make them. How is the map of India (link above) made? So that in the future I can make my own locator and location maps and I don't have to depend on the maps others have made. Citypeek (talk) 14:42, 31 October 2010 (UTC)
Not sure that there's any special technique for such maps as opposed to other maps, but you could compare File:Map of USA with state names.svg and File:Map of USA without state names.svg ... AnonMoos (talk) 17:01, 31 October 2010 (UTC)
No, the two maps above are easy. The question is how to draw one from scratch. Citypeek (talk) 03:31, 1 November 2010 (UTC)
And this is really the one I was looking for: [1] Citypeek (talk) 05:08, 2 November 2010 (UTC)
Then you're asking how to make SVG map files in general, and I don't know why you went through this whole long thing of specifying "locator" maps when that's in fact irrelevant... AnonMoos (talk) 05:13, 1 November 2010 (UTC)
Using Inkscape is not a problem for me. It is mapmaking with Inkscape that baffles me. How is it done? Look on this page [2] : someone is working on a tutorial (media:Tutorial-cartography_(basic).svg) but the tutorial is not finished yet. That is the thing that I am looking for. Citypeek (talk) 06:21, 1 November 2010 (UTC)
And this is the one I was looking for: [3]Citypeek (talk) 05:09, 2 November 2010 (UTC)
That tutorial would not produce a map acceptable for use on Commons, because it involves tracing a copyrighted Google map. The easiest way to create an SVG map is to trace another source, but for Commons purposes that source has to be free to use -- ideally in the public domain. You may want to take a look at en:Wikipedia:WikiProject Maps/Source materials. Powers (talk) 13:06, 3 November 2010 (UTC)
