Picsel HTML File Format Support 
Page 
ePAGE supports the most popular global file formats.  The formats 
interpreted by ePAGE are richly expressive, containing not just text but 
sophisticated layout and rendering features, rich fonts, colour, images, 
tables, graphics and many other document features.  Picsel is 
continuously developing its file format support to eventually cover every 
feature of the native file.  With such a wealth of features across many 
document types, this is inevitably an ongoing process, with milestone 
releases of new functionality planned at periodic intervals.  The 
approach involves researching the feature set most commonly found in 
real documents, building support early for the most frequently used 
elements, and ensuring these features are reproduced with total 
faithfulness to the original. The emphasis of ePAGE is on displaying rich 
content rather than on reproducing the document creation facilities of 
the original application. 
 
This document describes the features supported in ePAGE.  This level of 
support already covers the vast majority of characteristics that occur in 
day to day documents of this type, and the specific features are 
described with notes where appropriate.  Those features planned for 
future implementation are also described, for completeness. 
HTML 
Hypertext Markup Language is used for the text and structure of web 
pages on the World Wide Web. It was originally designed to represent 
scientific papers in a form that allowed different organisations to print 
them in different styles, but has since been extended to cover formatting 
and page layout issues, and of course to include pictures. 
 
HTML is easy to write. Even relatively non-technical people can write it 
directly into a text editor, including hypertext links to other pages, 
references to images, document formatting, colours, and other details. 
Unfortunately, decoding it is more difficult as there are many small 
errors which are interpreted in certain ways by popular software, and 
have become assumed to be part of the standard.
