GSoC 2012 Project : Rendering and Multithreading

Email: annapareddyjanardhanreddy@gmail.com

Short description:

Scribus is a great DTP application which is used to print many magazines and books. And a lot of these books contain many images. But loading of books/document for the first time takes much time. Reloading time of documents takes reasonable time (It gets the images from the cache). Moreover toggle from display to other modes is also slow. The idea of this project is to prepare preview images using multithreading. The idea is to fill the cache by worker threads and let the render thread use a dummy or previous version of the image.

Implementation Details :

Contingency :

This project might be completed before gsoc. Then i will start implementing the following features using multithreading

1) DocumentChecker (specialy for checking for issues in text frames)

2) output/printing

3) image effects

All these remaining things i will try to complete after gsoc one by one.

After GSOC :

I am highly motivated and interested in working for Scribus even after GSoC. I will continue working with the Scribus team, fixing bugs, and also on some of the specific projects i am interested in.
