• Design – Applied various design patterns to make the components more structured and decoupled.
• Development – Implemented basic features as specified in SRS document like, Unicode file format and XDK, Sending for the QuarkXPress 8.0. Used policy, proxy and factory based design to decouple Reading/saving of 7.0, 8.0. Moved old Handle and array based code to STL containers.
• Product configuration use Singleton pattern to control the features enabling/disabling based on the product version.
• Bug Fixing – Fixed critical Access-violation and Performance bugs in QuarkXPress 7.0, 8.0. Improved the performance of the File open/save operation on network location by using the FSExchange objects on MAC OS. To achieve the better performance in some cases by using the low level system commands.
• Made the File format Unicode Compliant –Porting to FSRef on Mac OS and usage of QXString library for Unicode string support.
• Refactoring and Performance Improvement– Changed the project open and save, AutoSave, Auto backup, revert to save implementation to support network files and long filename/pathnames. Also used multithreading to gain performance and stability on multiprocessor and dual core platform while dealing with network and read-only files, now on opening these file we read the Disk data (Text and pictures) by separate thread mechanism so that further access to data become fast and in case of network failure there would be less chances of the document corruption.
• Done the Exception handling to make code more robust and easy to maintain.
• File format support for the MAC Intel version of QuarkXPress application.
• Implemented “Sending” text and typography feature and integrate it with the Core QuarkXPress Text engine.
• Implemented of Iterator based design for the File format module of the EATextXT.
