Help needed with Image:MagicAmuletSquare.svg[edit]

  1. It needs to be cropped from portrait to square. (Is it possible to request a bot to do this, as it is with rotation?)
  2. It lacks categories.
  3. Perhaps some background on the ancient phrase (ROTAS OPERA TENET AREPO SATOR) the amulet incorporates.
  4. Anything else about it needs fixing? (Perhaps if someone does and uploads a new version in which the lettering is textual, not graphic, which should reduce the file size somewhat... I currently create SVGs by drawing them in Corel Draw 7, exporting to WMF and importing the result into Inkscape for the final save.)

It's fairly easy to fix margins by opening the file in a text editor and fiddling with the width, height, and viewBox attributes (as I did just now). It would be nice to have a basic description of what it is, but extended discussion shouild be reserved for the en:Sator Square article. I'm not sure what category to put it in; probably not occultism... AnonMoos (talk) 17:10, 2 July 2008 (UTC)

SVG Problem?[edit]

Can anyone help me to figure out why commons couldn't render this file, thx??Image:Map of Hong Kong 18Districts ZH.svg--ZHModdlygTalk+ 18:55, 5 July 2008 (UTC)

The SVG contains a reference to an external PNG file:
<image xlink:href="Hk_map_18.png" x="0" y="0" width="1454" height="1083" id="image2449" />

Urgent help needed with tomorrow's En main Page image[edit]

I've just uploaded a new image to commons, Image:William Gibson 60th birthday portrait.jpg that is used on the En article which will be on the Main Page tomorrow. I'd like someone to remove the border around the image and make any technical adjustments they see fit. (For bonus points, you could see to the other images in the article!) Thanks in advance, Astrojunta (talk) 18:27, 24 July 2008 (UTC)

Flip bot?[edit]

Is there a bot that flips images? -- carol (talk) 18:33, 24 July 2008 (UTC)

Hm, I only know of Rotatebot. --rimshottalk 19:05, 24 July 2008 (UTC)
They have a bot that will invert the colors of an image. I am still trying to think of a non-vandalism use for that one.... -- carol (talk) 19:57, 24 July 2008 (UTC)
If so, it would be great if the bot were to flip Earl of Athlone. Pharrar (talk) 22:12, 24 July 2008 (UTC)

Cropping - can it be done within Commons?[edit]

Following on from the idea of a "flip" or "rotate" bot, how about a "crop bot"? To crop I would currently have to download, crop and reupload an image. Wouldn't it be possible to do this within Commons? You could specify how much to take off from each side, though this would be difficult so an interface would probably be needed. That, in turn, would be quite a difficult thing to create, though it could potentially make cropping much easier (you could upload the crop as a new image or have it as a revision of the current one). Would it be used much though? Richard001 (talk) 03:18, 27 July 2008 (UTC)

How would you determine how much to take? I ask this because I would open it in an image editor because that is the easiest way to get an accurate pixel count. But then having it opened, I would select by color and invert the selection which probably would succeed (I am guessing) about 70% of the time -- the success of that depends on the borders being straight. The bots I have seen use jpegtrans and other tools like this which do not make selections. I wrote a script that made selections like this on a bunch of images, a lot depends on the image about where to make a selection like that. That was one of the many reasons that script did not go online with the others.
Perhaps a stylized page that has some pixel rulers on them; my brain is having problems thinking about if the resolution would easily work for that right now though. Interesting ideas though, in my opinion. -- carol (talk) 04:48, 27 July 2008 (UTC)
This cropping function could be really convenient ! By exemple, we can have a [Image:1942_world_map.svg] , and [[Image:1942_world_map.svg|cropped|start:x=5;y=5|end:x=10;y=0|200px|thumb|Map of Europe in 1942]]. Yug (talk) 13:47, 27 July 2008 (UTC)
More urgent right now : have we a page listing bots, especially bots able to act on images (rename; flip, crop) ? Yug (talk) 13:48, 27 July 2008 (UTC)
SVG is completely different to repair the borders of -- I am unable to think of how to make a software bot to do as simply as the suggestions I made for cropping bitmap images. There is a couple of places (project pages) that bots and their functions are listed and that requests can be made -- I would need to search around for them now the same as you would have to do.
The people who can write bots and have access to the privs the bots need to do these things should be reading this page, perhaps. -- carol (talk) 17:18, 27 July 2008 (UTC)
I just saw something in the recent uploads, User:Cropbot authored by User:Luxo operated today by User:ChristianBier and according to the user page, in test mode right now (birthday was either July 21 or June 21 this year) and if I read the documentation correctly, responds to {{Remove border}}. -- carol (talk) 10:50, 28 July 2008 (UTC)


Picture album layout[edit]

I have tried to use 2 galleries in one section. Result is bad. But why? Syntax is in article [1]:

begin gallery

image

end gallery


picture


begin gallery

end gallery
