This uses a scanned file of a physical work to create an Index page, from which Page pages are created, which are eventually transcluded into the main namespace for anyone to read. These days, the ProofreadPage Extension can use different formats for the scanned file. This was not always the case.

Since then, the PDF format has changed; it is now acceptable for Wikisource's purposes and covered by the extension.

DjVu is specifically designed to enable the creation of digital libraries of high-visual-quality documents either scanned from paper or produced in other digital formats. It relies on advanced content analysis techniques to segment a scanned color page into layers and achieve high compression ratios, low memory utilization, extremely fast rendering on screen and indexing of the material. DjVu offers a means not only of preserving documents, but also making them truly accessible and usable across and throughout the digital world regardless of available bandwidth or the origin, complexity or size of the originals. File size and image quality are the perennially opposing forces in digital documents.

Он достаточно долго проработал бок о бок с директором и знал, что перерыв не относился к числу поощряемых им действий - особенно когда дело касалось ТРАНСТЕКСТА.

Одновременный подрыв этих тщательно замаскированных устройств должен был создать магнитное поле такой мощности, что вся информация на магнитных носителях - жестких дисках компьютеров, в постоянных запоминающих устройствах, в резервных файлах и даже на гибких дисках - оказалась бы стерта. Все данные, свидетельствующие о том, кто чем владел, должны были исчезнуть навсегда. Поскольку для одновременного подрыва устройств была необходима точнейшая координация действий, все эти изделия были связаны между собой телефонными линиями через Интернет.

Из Испании опять пришли плохие новости - не от Дэвида Беккера, а от других, которых он послал в Севилью. В трех тысячах миль от Вашингтона мини-автобус мобильного наблюдения мчался по пустым улицам Севильи. Он был позаимствован АНБ на военной базе Рота в обстановке чрезвычайной секретности.
