PanoView DokuWiki Plugin

Over the last few days, I built another DokuWiki plugin. It's called PanoView.

The plugin allows you to embed really large images into your wiki pages without clogging people's bandwidth. The feature works similar to Google Maps. The large original image is sliced up into several smaller tiles. Only visible tiles are downloaded. The image can be panned and zoomed.

This might be useful to display construction drawings or medical photos, but works great for panorama images, too.

For better understanding, just have a look at the example below (RSS readers need to click through for the JavaScript version).

The image shows San Francisco after the big earthquake in 1906. The original scan is a 156MB TIF which I converted into the 13MB JPEG shown above. The image dimensions are 11709×4716 pixel (about 55 Megapixel).

The image tiling is done on the fly when viewing an image in the PanoView plugin for the first time. Subsequent view are served from cache.

The plugin is available here: plugin:panoview.

This is awesome.

Side note: Tabbing through the comment form is half broken with your new layout, as tab seems to select the label as well... or something

Hmm, tabbing works just fine for me!? What browser do you use?

How are the smaller images made? I haven't looked at the plugin yet; I was just wondering.

The tiles are generated on the fly when they are requested using either libGD or Image Magick (I really recommend the latter to avoid memory problems). They are cached of course, so only the first call is somewhat slow.

Looks great! My question is: Can this plugin be used to show an image on a post in a Wordpress blog? In that case how should I install the plugin?

Thanks in advance!
