A method for acquiring and editing custom graphics and a subtitle graphics production system

Abstract

The invention provides a method for acquiring and editing custom graphics and a system for making subtitle graphics, wherein the method specifically comprises: a making step: making a plug-in depending on the custom graphics required by the current user; the plug-in is used for providing a description of a key point and a control point of the required custom graphics, and the plug-in carries forward the interface of the main program protocol layer of graphics drawing; a loading step: receiving a custom graphics selected by the user and acquiring corresponding information from the plug-in; a first display step: drawing and displaying the custom graphics according to the acquired information; a changing step: receiving the movement of a certain control point by the user and passing the changed information to the plug-in via the interface; a calculating step: recalculating key point information by the plug-in after receiving the changed information and passing the information to the graphics drawing main program; and a second displaying step: displaying according to the key point information returned by the plug-in. The method in the invention is used for improving the efficiency of drawing graphics.

Description

technical field [0001] The invention relates to the technical field of computer graphics, in particular to a method for acquiring and editing custom graphics and a subtitle graphics production system. Background technique [0002] The main research content of computer graphics is to study how to represent graphics in computers, as well as the related principles and algorithms of computing, processing and displaying graphics using computers. Graphics are usually composed of geometric elements such as points, lines, surfaces, and volumes, and non-geometric attributes such as grayscale, color, line type, and line width. From the perspective of processing technology, graphics are mainly divided into two categories, one is based on line information representation, such as engineering drawings, contour maps, wireframes of curved surfaces, etc., and the other is light and shade maps, which are commonly referred to as Photorealistic graphics. Computer graphics technology is widely...

However, the graphic elements in the library are generally limited, for example, only basic graphic elements such as lines, rectangles, ellipses, and arcs are provided, so that when users need to draw free curves, the graphic element library cannot meet the demand at all; or , when there is demand for complex graphics such as parallelograms, rhombuses, trapezoids, triangles, and pentagons, users have to draw the required graphics line by line, which seriously affects the efficiency of graphics drawing
