|
||||
pdf2htmlEX renders PDF files in HTML, utilizing modern Web technologies.
|
||||
It aims to provide an accuracy rendering, while keeping optimized for Web display.
|
||||
|
||||
It is optimized for modern web browsers. On Linux/Mac, the generated HTML pages could be as beautiful as PDF files.
|
||||
pdf2htmlEX is best for text-based PDF files, for example scientific papers with complicated formulas and figures.
|
||||
Text, fonts and formats are natively perserved in HTML such that you can still search and copy.
|
||||
The generated HTML file is static, Javascript is not required.
|
||||
|
||||
This program is designed for scientific papers with complicate formulas and figures, therefore precise rendering is the #1 concern. But of course general PDF files are also supported.
|
||||
|
||||
### Why HTML ?
|
||||
|
||||
HTML, together with CSS and Javascript, is much more open and flexible than PDF. Almost everything can be customized.
|
||||
- Embedding documents to web pages with consistent theme and behavior
|
||||
- Cross references to other documents are much easier and intuitive
|
||||
- More functions to the document with Javascript, e.g. access control, animation, statistics
|
||||
|
||||
Readers can also be benefitted
|
||||
- Read while downloading
|
||||
- Plugin-free

|
||||
When split-pages is 0, the manifest file describes how the final html page should be generated.
|
||||
|
||||
By default, pdf2htmlEX will use the manifest in the default data-dir (run `pdf2htmlEX -v` to check), which gives a simple demo of its syntax.
|
||||
|
||||
You can modify the default one, or you can create a new one and specify the correct data-dir in the command line.
|
||||
|
||||
When single-html is 1, all files referred by the manifest must be located in the data-dir.
