COLiER: Collaborative Editing of Raster Images
arXiv - CS - Graphics Pub Date : 2021-07-13 , DOI: arxiv-2107.05962
Ulrike Bath, Sumit Shekhar, Jürgen Döllner, Matthias Trapp

Various web-based image-editing tools and web-based collaborative tools exist in isolation. Research focusing to bridge the gap between these two domains is sparse. We respond to the above and develop a prototype groupware for real-time collaborative editing of raster images in a web browser. To better understand the requirements, we conduct a preliminary user study and establish communication and synchronization as key elements. The existing groupware for text documents, presentations, and vector graphics handles the above through well-established techniques. However, those cannot be extended as it is for raster graphics manipulation. To this end, we develop a document model that is maintained by a server and is delivered and synchronized to multiple clients. Our prototypical implementation is based on a scalable client-server architecture: using WebGL for interactive browser-based rendering and WebSocket connections to maintain synchronization. We evaluate our work qualitatively through a post-deployment user study for three different scenarios.

COLiER:光栅图像的协同编辑

各种基于 Web 的图像编辑工具和基于 Web 的协作工具是孤立存在的。专注于弥合这两个领域之间差距的研究很少。我们响应上述问题并开发了一个原型群件,用于在 Web 浏览器中实时协作编辑光栅图像。为了更好地了解需求,我们进行了初步的用户研究,并将沟通和同步作为关键要素。现有的用于文本文档、演示和矢量图形的组件通过成熟的技术处理上述问题。但是,这些不能扩展,因为它用于光栅图形操作。为此,我们开发了一个由服务器维护并交付并同步到多个客户端的文档模型。我们的原型实现基于可扩展的客户端-服务器架构:使用 WebGL 进行基于浏览器的交互式渲染和 WebSocket 连接以保持同步。我们通过针对三种不同场景的部署后用户研究来定性地评估我们的工作。
