Formula display method, device, terminal, and computer-readable storage medium

Abstract

Disclosed in the present invention is a formula display method, comprising: obtaining the layout patterns of all elements nested in multiple levels in a formula to be displayed and position relationships between the elements in each nesting level; invoking the height to be displayed and / or aligning line information of one or more child elements of non-basic elements according to the layout patterns of the non-basic elements, and calculating the heights to be displayed and / or aligning line information of the non-basic elements; arranging all the child elements according to the aligning line information of all the child elements of expression combinations, so as to make the aligning line information of all the child elements the same; and displaying the formula of the arranged child elements of all the expression combinations according to the position relationships between the elements in each nesting level and the height to be displayed of each element. Correspondingly, also disclosed in the present invention are a formula display apparatus, a terminal, and a computer-readable storage medium. The present invention implements efficient and aesthetic display of a formula, and achieves the effect of clearly displaying the structure of the formula to users.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a formula display method, device, terminal and computer-readable storage medium. Background technique [0002] The teaching touch screen terminal is a multifunctional device developed on the basis of conventional audio-visual education and computer equipment. It has the functions of teaching, academic reports, conferences, etc., and meets the requirements of modern education for demonstration of various resources. [0003] Using the whiteboard software provided by the teaching touch-screen terminal, teachers can write on the whiteboard just like writing on a traditional blackboard. However, no matter on the traditional blackboard or whiteboard software, there is often a problem that the formulas are not displayed clearly due to the teacher's scribbled handwriting. Although the teaching touch screen terminals in the prior art can recognize the characters and layou...
