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

Abstract

The invention discloses a formula display method which comprises the steps that a layout pattern of all elements which are nested in multiple stages in a to-be-displayed formula and the position relations among the elements in each nesting stage are obtained; the to-be-displayed height and / or aligning line information of one or more sub-elements of a non-polaron element are / is called according to the layout pattern of the non-polaron element, and the to-be-displayed height and / or aligning line information of the non-polaron element is calculated; all sub-elements are arranged according to the aligning line information of all sub-elements of expression combinations, and the aligning line information of all the sub-elements is made same; formulas of the sub-elements of all expression combinations are displayed and arranged according to the position relations among the elements in each nesting stage and the to-be-displayed height of each element. Accordingly, the invention discloses a formula display device, a terminal and a computer readable storage medium. According to the formula display method and device, the terminal and the computer readable storage medium, the formulas are displayed efficiently and attractively, and the effect that the formula structures are clearly displayed to the user is realized.

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...

However, no matter on the traditional blackboard or whiteboard software, there is often a problem that the formula is 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 layout patterns in the formulas by means of image processing, they cannot align and arrange the elements in the formulas to display the formulas beautifully.
