Abstract

Graphics editing in current bitmap collaboration models suffers from issues such as large volume of data transmission, poor flexibility, overlapping conflicts and storage pressure. To solve these problems, this paper proposed a collaborative editing model for complex bitmaps. Collaborative operation sent only the coordinates and color change, had featuring low data volume, multi-dimensional granularity, and overlapping position. It added a four-dimensional bitmap collaborative architecture with spatio-temporal relationship, and only saved the edited pixel data to save more storage space. It used the replica state control algorithm based on rollback to ensure that the operations were executed on correct replica by reconstructing historical versions backward. It could dynamically generate branch versions according to the current state and policy configuration to solve the problem of too many branch versions. Finally, this paper inferred model correctness based on the CCI model, deve-loped a prototype collaborative editor "Co-Pixel", and executed the experiments based on randomly generated operation sets and simulated the actual editing behavior against Adobe Lightroom. Results show that this model can avoid conflicts between independent operations to a greater extent, reduce the algorithmic overhead in the consistency maintenance process, flexibly adjust the intent retention policy and generate a version of the result that reduces the user's intent maintenance effort.
