Document engineering for a digital library
Petr Sojka, Radim Hatlapatka · 2010
This paper describes several innovative document transformations and tools that have been developed in the process of building the Digital Mathematical Library DML-CZ http://dml.cz. The main result presented in this paper is our PDF re-compression tools developed using a jbig2enc library. Together with other programs, especially pdfsizeopt.py by Péter Szabó, we have managed to decrease PDF storage size and transmission needs be 62%: using both programs we reduced the size of the original PDFs to 38%.
