For example, the vector graphic identifiers in the data frames 4 and 8 are static vector graphic identifiers, so that all vector graphics on the canvas need to be emptied, and then the vector data in the data frames are loaded, and since all vector graphics on the current canvas are stored for the static vector graphics during acquisition, all graphics in the recorded canvas can be displayed by emptying the canvas during playback; for another example, the vector graphics identifiers in the data frames 6 and 7 are dynamic vector graphics identifiers, when the data frame 7 is loaded, the vector graphics corresponding to the data frame 6 is displayed on the current canvas, the dynamic vector graphics in the data frame 6 is replaced by the dynamic vector graphics corresponding to the data frame 7, and the static vector graphics in the data frame 7 is the same as the data frame 6, and therefore remains unchanged.

In addition, according to the data frames stored in the vector data file, the corresponding vector graphics are played back, the playback process is the same as the sequence of recording the data frames, and the dynamic display effect can clearly show the drawing process; further, vector graphics stored in the form of data frames are displayed in a zooming mode during playback, the vector graphics are displayed on the basis of the vector data in the data frames, and the resolution of the vector graphics during playback and the display effect of a screen can be guaranteed.
