I've switched to specifying width rounded to 100s; however, the API still gives me one-off images (599 instead of 600 px). I could hack the API thumbnail URL, though. Better yet, I can probably skip that step entirely after the first one... > Also, for the text, I just had a crazy idea : instead of > requesting the text of each page, you can do a single > request for the whole book, using &action=parse (pass the > <pages/> command to it, as in this script : > http://wikisource.org/wiki/MediaWiki:Dictionary.js ). > > Then we can split the returned string with a regexp that detects > the page breaks (they are in a special span element), and place > it in the corresponding divs ; things will break whenever a html > formatting element ends on a different page than where it > begins, but we could write a function that balances the > missing elements. Why load a giant text and then hack around on broken HTML, when I can just query each page individually? It's not really slow, at least not in Google Chrome. Meanwhile, I added a feature to hide "header elements" like the proofread line, which kind of disrupts the reading flow. There's a checkbox to toggle header display. And for Klaus, I added de.wikisource: http://toolserver.org/~magnus/book2scroll/index.html?lang=de&numlen=3&file=Reymont_-_Der_Vampir.djvu&startpage=5&pages=318 Cheers, Magnus _______________________________________________ Wikisource-l mailing list Wikisource-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikisource-l
