The focus of the readings this week is digital images. The Lesk and ARMS texts delved into the complexities of presenting a digital form of a text. Some of the issues covered are format, programming languages, and the ability to search the text. The topic of converting a printed text into a digital document, in particular, received a large level of attention. The quality of a scanned text depends on certain variables, including resolution. A text in a PDF file, for instance, is not a digital text; it is an image of a text.
Presentation of digital materials is an important issue with Websites. A digital library, after all, is a Website. The programming language used determines the technical details of a site. Languages like HTML, SGML, and XML require different specifications. The codes controlling the appearance of digital material are usually separate from the content being displayed.
