Description

一种修改公式运算符的方法和装置 Method and device for modifying formula operator

技术领域technical field

本发明涉及排版技术领域，特别涉及一种修改公式运算符的方法和装置。The invention relates to the technical field of typesetting, in particular to a method and device for modifying formula operators.

背景技术Background technique

在排版技术领域，公式的交互操作是一个非常重要和实用的技术，一种很好的交互设计不仅可以增强公式的排版效果，还可以加快排版效率，降低排版难度和工作量。In the field of typesetting technology, the interactive operation of formulas is a very important and practical technology. A good interactive design can not only enhance the typesetting effect of formulas, but also speed up typesetting efficiency and reduce typesetting difficulty and workload.

目前的排版软件在对公式排版时不支持对公式运算符的修改。如果用户想对公式运算符进行修改，比如替换公式运算符，则用户需要将公式运算附中的数据一起修改。The current typesetting software does not support the modification of formula operators when typesetting formulas. If the user wants to modify the formula operator, such as replacing the formula operator, the user needs to modify the data attached to the formula operation together.

比如用户想把直的分数线替换成斜的分数线，则必须把公式删除(即该运算符和其所带的数据必须一起删除)，然后再重新输入新的运算符。For example, if the user wants to replace a straight fraction line with a slanted fraction line, the formula must be deleted (that is, the operator and the data it carries must be deleted together), and then a new operator must be re-entered.

目前排版领域中，如果想要修改公式运算符必须将公式删除，然后在重新输入需要的公式。In the current typesetting field, if you want to modify the formula operator, you must delete the formula, and then re-enter the required formula.

综上所述，目前在公式排版中，不支持对公式运算符的修改，从而增加了修改公式运算符的复杂度和时间，降低了用户体验。To sum up, at present, the modification of formula operators is not supported in formula typesetting, which increases the complexity and time of modifying formula operators and reduces user experience.
