Abstract

The invention discloses a record broadcasting, class recording system writing stroke processing and displaying method. The method includes: judging whether the time interval between stop writing and start writing exceeds preset time; storing multiple strokes, not exceeding the preset time, in the same stroke storage unit, and drawing the multiple strokes in the same bitmap; if the preset time is exceeded, by the system, generating a new stroke data unit and a blank bitmap; displaying stroke data, as a display entity, of the same stroke data unit. By the method, the problems that the existing record broadcasting, class recording systems use a single stroke as a unit for storage, processing and display, moving and turning operations are complex, and display speed is slow are solved. During redisplay, the method does not need redrawing, stroke display information is called directly, and stroke display efficiency of the record broadcasting, class recording system in computers is increased.

Description

technical field

[0001] The field that the present invention relates to is a method for processing and displaying written strokes in a recording, broadcasting and class recording system. Background technique

[0002] As a new teaching and conference tool, recording, broadcasting and class recording systems have been applied in many schools and conference rooms. There are often a lot of blackboard writing in the teaching process. During the teaching process, it is often necessary to move these blackboard books or perform page-turning operations. For the display mode of the computer, it includes several layers of architecture such as hardware devices, device drivers, display interfaces, and application programs. Such as figure 1 The Windows system display architecture shown includes hardware devices, device drivers, GDI (graphics device interface), GDI+ engine for drawing graphics, images, and text, and platform layers (.NET, WIN32 / 64 (C++)). In order to facilitate porting,...
