Typesetting method of online mathematical fraction

Abstract

The invention discloses a typesetting method of an online mathematical fraction. The typesetting method comprises the following steps: analyzing DOM elements of a document; identifying a mathematicalfraction; recognizing a molecule; identifying denominators; converting fractions; a conversion molecule; adding a fractional line effect; converting denominators; calculating the sum of the number ofmolecules and the number of the denominators, and recording as N; and adding line content: adding the line content before the fraction and adding the line content after the fractions, and finishing the re-typesetting of the mathematical fractions. A identifier is added into the HTML document, and the display position of the mathematical fraction is calculated in the script; the content of the rowwhere the mathematical fraction is located is calculated, the content of the molecules and the denominators in the row is updated, the mathematical fraction is described in a table mode, the effect ofcorrectly displaying the mathematical fraction in most browsers is achieved through the typesetting characteristic of the table, secondary editing can be conveniently carried out, the whole process is rapid, and efficiency is high.

Description

technical field [0001] The invention relates to a typesetting method for online mathematical fractions, in particular to an online typesetting method for mathematical fractions that can be correctly displayed in most browsers and can realize secondary editing. Background technique [0002] With the advent of the WEB Internet era, more and more mathematical formulas need to be presented on web pages. A mathematical fraction is a common mathematical formula, that is, a mathematical formula including a numerator, a denominator, and a fraction line. [0003] The existing mathematical formulas are described in laTex or MathML language, and the current implementation of the two uses the addition of <span style＝″border-bottom-width：0.04em；″> The numerator and denominator use a complex positioning method, which results in complex calculations and low rendering efficiency, while MathML has a high learning threshold and is not compatible with many browsers. [0004] In addition, ...

Problems solved by technology

[0003] The existing mathematical formulas are described in laTex or MathML language, and the current implementation of the two uses the addition of The numerator and denominator use a complex positioning method, which results in complex calculations and low rendering efficiency, while MathML has a high learning threshold and many browsers are not compatible

[0004] In addition, there is another general rendering method that uses pictures and converts mathematical fractions into images for display. Its advantage is that it will not cause deformation, misalignment, etc. in different display environments, but when using pictures, it will lead to formula 2 It is difficult to edit once, and the efficiency is low when zooming in, and problems such as image blurring will occur when zooming in

[0005] Therefore, there is currently no typesetting method for online mathematical fractions that has high rendering efficiency, can be displayed correctly in most browsers, and can realize secondary editing
