CUPS Filters: Converting Filters to Filter Functions

Introduction

CUPS-Filters provide the filters which CUPS needs to convert job data from the input data to the printer's native language. Filters enable a user to print a file even if the printer does not support the file format. Currently some filters are in the form of standalone executables. This uses a lot of CPU resources for running printer applications due to so many calls for each individual executable. So the primary focus of this project is to convert a few filters (pdftoraster, texttopdf, bannertopdf) into filter functions. These functions would be integrated in a shared library so as to reduce the number of calls to individual filter executables and minimize CPU resources exploitation.
