Embodiment Construction

[0024] The visual editing system 5 for scientific formulas at least includes an input interface module 2 , a data layer module 3 and a typesetting display module 1 .

[0025] Input interface module 2, described input interface module 2 provides the user interface of standard scientific formula element and input scientific formula window at least, receives the information that the visual editing system 5 of this scientific formula is edited from peripheral equipment such as keyboard, mouse input ;

[0026] The data layer module 3, the data layer module 3 receives the formula transmitted from the input interface module 2 to format and serialize, when receiving the typesetting display command of the scientific formula, it performs the XML of the scientific formula stored in the file 4 The format is converted into the form of the corresponding object class, that is, format conversion, typesetting and display preprocessing; the data layer module 3 mainly implements data format conv...

Abstract

The system consists of input boundary surface module providing user boundary surface of standard formula element and input formula window to receive formula inputted by user and to send information to data layer module, data layer module receiving formula transmitted from boundary surface module and toconvert it to be corresponding XML mark stored in file as well as to convert XML mark in file to be object form when command of formula composing display is received, and composing display module receiving data transmitted from data layer module and to carry out composing display.

Description

technical field [0001] The invention relates to scientific formulas, in particular to a visual editing system and method for scientific formulas. Background technique [0002] At present, the most commonly used formula editor is the Microsoft Equation Editor used in office software. This editor is convenient for users to enter formulas, but it has the following deficiencies. [0003] (1) The formula edited in this editor is used as an OLE (Object Linking and Embedding) embedded object to be integrated into other applications that support the OLE standard, and the host document can be embedded in OLE mode, which can be scaled arbitrarily, bringing the entire text The formula format of the document is not uniform, which affects the layout of the entire document. And the formula is not cross-platform by using OLE method. [0004] (2) The editor can only input some fixed mathematical symbols, which is not expansible, and the user needs to input not only numerical formulas, bu...
