Object-Parsing And Layout Optimization For Composite Presentation Documents

The composite presentation document is a kind of digital media composed of elements such as text,graphics,images,color matching,etc.,which are widely used in magazine covers,PPT(PowerPoint)documents,posters and other aspects.Using a good composite presentation can make the content clear and vivid,and the use of low-quality composite presentations can not only effectively convey information,but also make the information misunderstanding of the audience.Therefore,how to help design inexperienced users to complete the composite presentation design quickly and efficiently is of great significance.Taking PPT document design as an example,this paper proposes an object-based parsing and layout optimization system for composite presentation documents for the four most frequently used elements in the document: text,graphics,images,and color matching.Firstly,the system firstly analyzes and summarizes the visual structure and combined structure characteristics of PPT documents,the planar aesthetic design method and the principle of human vision.The theoretical model of automatic layout optimization is composed of many design principles.Each design principle is for one design principle.Or elements within multiple PPT documents.At the same time,the system uses the object-based parsing method of the PPT document to parse the above four types of elements,and utilizes the association characteristics that may exist between the element itself and the elements,such as the position attribute,size attribute,element entry order,and number of elements between the elements.Features,etc.,get the classification of the parsed elements and the matching relationship between the elements.Finally,based on the optimization theory model and the matching relationship between elements,the system realizes the overall automatic layout optimization and element attribute optimization for the elements that are classified.The experimental results show that the designed prototype system can achieve better automatic layout optimization for PPT documents containing four basic elements.At the same time,users can more easily improve their PPT design capabilities based on the final optimization results.
