Usage

Please note that this component only accepts in-line mathematics. Learn more

import { MathJaxSvg } from 'react-native-mathjax-html-to-text-svg';
...

<MathJaxSvg 
  fontSize={16}
  color="red"
  fontCache={true}
>
  {'$$4sen(α)cos^2(α/2)$$'}
</MathJaxSvg>

Using TeX or LaTeX with html

import { MathJaxSvg } from 'react-native-mathjax-html-to-text-svg';

return (
    <MathJaxSvg 
      fontSize={16}
      color="#000000"
      fontCache={true}
    >
      {`
        <p>When \\(a \\ne 0\\), there are <u>two solutions</u> to \\(ax^2 + bx + c = 0\\) <span style="color:red;">and</span> they are $$x = {-b \\pm \\sqrt{b^2-4ac} \\over 2a}.$$</p>

Output

Props	Default	Description
fontSize	14	The font size for displaying the formula. Note that it will also apply to regular text. Regular text can accept inline styles if HTML has inline styles.
color	"#000000"	The color of the formula to display. Note that it will also apply to regular text. Regular text can accept inline styles if HTML has inline styles.
fontCache	false	MathJax will cache font paths on an expression-by-expression basis (each expression has its own cache within the SVG image itself), which makes the SVG self-contained, but still allows for some savings if characters are repeated.
style	{ flexDirection: 'row', flexWrap: 'wrap', alignItems: 'center', flexShrink: 1 }	Container style
styles	{ container: Styles for the container wrapping the entire component. mathSvgs: Styles for the SVG elements generated by MathJax. formattedTextStyles: Styles for the formatted text elements. scrollContainerStyle: Styles for the scrollable container when equations are too wide. heading1, heading2, heading3, heading4: Styles for different heading levels. paragraph: Styles for paragraph text. bold: Styles for bold text. table, tableRow, tableHeader, tableCell, firstRow: Styles for table elements. }	Allows overriding default styles for specific components within MathJaxSvg.
