Fwd: [Clipart] Clipart mining guide
by Brianna Laugher 17 Oct '07

17 Oct '07

Could be good for Commons to have some help files on the best practices of extracting illustrations (if not clipart...) from scans. So this may be of interest and maybe folks here have some advice for using Gimp etc too. cheers, Brianna ---------- Forwarded message ---------- From: John Olsen <johnny_automatic(a)mac.com> Date: 17 Oct 2007 13:21 Subject: [Clipart] Clipart mining guide To: clipart(a)lists.freedesktop.org I have had a couple of people ask me to go through the steps I use to get images from old books. I am happy to share them. I can only do a version using an Adobe Creative Suite workflow as this is what I am most familiar with and it seems the GIMP needs some additional helpers to handle PDFs. So I imagine this all can be done with an Open Source workflow. I just am not the authority to write on it. Maybe someone can translate it. Anyway, I have a draft below. I was thinking of adding it to the Wiki section "http://openclipart.org/wiki/Clipart_Acquisition" but wondered if that clutters up that section. maybe it is better in a separate subsection under either "Clip Art Information" or "Contributor & User Handbook". If so someone who can unlock the top level would need to set that up for me. Ryan? Any suggestions or ideas are appreciated. John Olsen == Guideline for Mining Images from Online Book Libraries == * Sites such as those collected under the texts section of www.Archive.org offer a gold mine of Public Domain images. This is a guide to how to extract these images for use here on OCAL. Please note the author uses a workflow using Adobe Creative Suite 3 because he is most familiar with this software. It probably can all be done using Open Source software. Someone else will need to add those instructions. * Find a book with images you would like to extract. Keep in mind that the resolution is not extremely high so small images may not have enough resolution to extract good SVGs. * Download the PDF version of the book. It usually has the best resolution. The black and white PDF will be made for reading the text and might not have the best images. it is better to get the full color PDF and do your own adjustments. * Open the PDF in Photoshop. You will be asked to select a page. Pick the page you want and open it. Then crop the image tight around the graphic you want. * Alternatively you can extract individual pages using Adobe Acrobat and then open these single pages in Photoshop. This can be faster and less memory intensive when mining large books. * Using Image>Adjustments>Black & White convert the image to black & white. The High Contrast Red Filter Preset usually does a good job. * Further enhance the image using Image>Adjustments>Brightness/Contrast to increase contrast and brightness if necessary so you get a nice high contrast image. * Save the file as .PSD or .TIF or any format that Adobe Illustrator opens. * Open this file in Adobe Illustrator. * Use Live Trace to convert photo to vector art. The following presets usually give the best result. One Color Logo (give black lines only-smallest file size), Black & White Logo (white parts are filled shapes as well) and Comic Art. * When happy with the image, Save as SVG. Do not preserve Illustrator editing so file is basic SVG. * Using File>Save for Web & Devices make a PNG file to upload with SVG. * Upload file to OCAL. * You usually get better results with strong black & white images. They make nice clean traces with reasonable file sizes. It is easier to color these afterwards then try to trace a full color image and expect clean, crisp lines. _______________________________________________ clipart mailing list clipart(a)lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/clipart -- They've just been waiting in a mountain for the right moment: http://modernthings.org/

Are you planning to make it possible for others to mirror, or release any kinds of image dumps? or torrents? or send people disks in the mail? cheers Brianna -- They've just been waiting in a mountain for the right moment: http://modernthings.org/

Durova tries to get us more pics
by David Gerard 10 Oct '07

10 Oct '07

http://searchengineland.com/071009-084922.php This is not the dazzling polished work of wonder she wanted it to be, as her hard disk went BANG on the weekend and she had to rewrite the whole thing from scratch yesterday. I added ideas and some quotes. I think the Richard Schiff vs Michele Merkin appproach might make the point clear! - d.

International Cleanup Weekend (October 13th and 14th)
by Eugene Zelenko 09 Oct '07

Hi! This is complete off topic, but... We all take great care about our small but constantly growing online world Commons. However, physical world still need care too. I invite you to join a Google cause: http://maps.google.com/help/maps/cleanup/. Not because of Google PR, but because of great idea. I think to clean up a place where I took all my dragonflies images - there are many broken glass battles around. With best regards, Eugene.

InGimp - instrumented Gimp for user interface research
by David Gerard 09 Oct '07

09 Oct '07

http://www.ingimp.org/ InGimp is an initiative at the Human-Computer Interaction department of the University of Waterloo. It's the Gimp, but it gathers anonymised data on how you use the application. If you use the Gimp, you may wish to start using InGimp so as to influence future Gimp versions to your way of working! Present version is 2.2.17. I've emailed asking about plans for a version of 2.4 (presumably when 2.4.0 final is released). I installed InGimp on Windows and it picked up my Gimp preferences just fine. Everything works the same. - d.

Automatic messages to users: guessing user preferred language
by Alexandre NOUVEL 07 Oct '07

07 Oct '07

Hi list, I've seen that some users run bots that add some message templates to user talk pages, generally in order to warn them about missing tags and other similar problems. The problem is that bots are not able to guess the preferred user language :) As for now, here are some clues about the user preferred language: * he has a Babel box on his user page or on his talk page => the highest skill could do it * he has a Welcome template or another message template that is not in English => get the lang code from the template translation subpage, but actually this is quite difficult because templates are generally subst'd and no link remains to the translation page... Then, which tools could we set up to know in an easier way the user preferred language? I'd say: * other users check the user contributions and guess his preferred language, then add some {{guessed language|<language code>}} template to the user talk page. This very template would provide information about how to add a Babel box. This is not much better than adding a Welcome template, so I don't think it to be a good solution. * some toolserver asking the database and returning as raw text the preferred language code that the user has set up in his preferences. This seems to me the best way to handle automatically this information, but shall assume that the user has set up this information. I think it's okay because when we need to contact this user, that's because he interacted on the project and has a high probability of having set up his preferences... Any thoughts? Any volunteers to code such a simple tool? :) Best regards from France, -- Alexandre.NOUVEL(a)alnoprods.net |-> http://alnoprods.net |-> L'encyclopédie libre et gratuite : http://fr.wikipedia.org \ I hate spam.

File types brainstorm
by Brianna Laugher 06 Oct '07

06 Oct '07

Hello all, It seems to me we haven't added any new file formats/types for a while now. Are there any we should work on adding? Are there any reasons we shouldn't add them? - something for Blender? (sth. like game environments if my impression is correct) - SMIL? (open standard alternative to Powerpoint, I think) - Open Office 2 formats? - what would be best for animations? I would find it hard to believe that GIF is optimal... TIFF was mentioned on wikitech-l recently. The comment was made that anything TIFF should really be a better format: jpg for photographs and djvu for scans, and maybe png for anything else. TIFF tiles are typically huge and all those options are much smaller. Someone else commented on the VP that we have no documentation on DjVu which I found to be true, from how to create DJvu files, to how to use them in MediaWiki. I had a look on mediawiki.org and couldn't find anything too useful either. So any hints here would be appreciated. cheers, Brianna -- They've just been waiting in a mountain for the right moment: http://modernthings.org/
