The characteristics and production processes of meteorological chart for TV service,and functions of Photoshop script are analyzed in this paper,hence the design of meteorological TV chart production system based on Photoshop scripting is proposed.The commands in Photoshop script,such as calling of the basic object model classes and delivery process of external variables,are demonstrated through a case of bar graph production.The Photoshop script can produce meteorological TV chart automatically in accordance with the variety and size of meteorological data without additional hardware requirement,which can improve the efficiency of meteorological TV chart production.
