# Native Android library to render latex with HTML support
## Introduction
In the realm of Android development, the struggle with sluggish equation rendering has been all too real. RenderX steps into the spotlight as a game-changing solution, not only accelerating LaTeX rendering but also seamlessly handling HTML with a nuanced fallback mechanism.
#### The Dual Power of RenderX
1. **Native Rendering Excellence:**
- Bid farewell to the performance bottlenecks associated with webviews. RenderX champions native rendering, dramatically enhancing the speed of LaTeX equation display on Android. Our benchmark tests reveal a 50-80% improvement, translating to a more responsive user experience.
So we have captured the frame rate graph while rendering Latex equations in RenderX vs MathJax. The difference can be visually seen.

2. **HTML + LaTeX Synergy:**
- One of RenderX's standout features is its ability to seamlessly render LaTeX embedded within HTML. This means developers can pass HTML with LaTeX equations directly, unleashing a new realm of possibilities. To illustrate its prowess, we've included real-world scenarios where HTML and LaTeX coexist harmoniously.
```markdown
Example
RenderX(
latex = "
LaTeX Equations:
\n" +
"\n" +
" Example 1: Equation 1 \\(e^{i\\pi} + 1 = 0\\)
\n" +
"\n" +
" Example 2: Equation with fractions \\[ f(x) = \\frac{1}{2\\pi i} \\oint_C \\frac{f(z)}{z-z_0} \\, dz \\]
\n" +
"Example 3: Quadratic formula \\(x = \\frac{{-b \\pm \\sqrt{{b^2 - 4ac}}}}{{2a}}\\)
\n" +
"\n" +
" Example 4: Maxwell's equations\n" +
" \\[\n" +
" \\begin{aligned}\n" +
" \\nabla \\cdot \\mathbf{E} &= \\frac{\\rho}{\\varepsilon_0} \\\\\n" +
" \\nabla \\cdot \\mathbf{B} &= 0 \\\\\n" +
" \\nabla \\times \\mathbf{E} &= -\\frac{\\partial \\mathbf{B}}{\\partial t} \\\\\n" +
" \\nabla \\times \\mathbf{B} &= \\mu_0 \\mathbf{J} + \\mu_0\\varepsilon_0 \\frac{\\partial \\mathbf{E}}{\\partial t}\n" +
" \\end{aligned}\n" +
" \\]
\n" +
"\n" +
" Example 5: Dirac equation \\(\\gamma^\\mu (i\\hbar\\partial_\\mu - e A_\\mu) \\psi - m c \\psi = 0\\)
\n"
)
```
Output
3. **Versatile HTML Rendering:**
- RenderX isn't confined to LaTeX alone; it excels in rendering pure HTML content with equal finesse with support of rendeing images via coil. Explore scenarios where the library effortlessly handles diverse HTML content, making it a versatile choice for rendering beyond mathematical equations.
4. **Intelligent Fallback Mechanism:**
- In complex scenarios where native rendering faces challenges, RenderX gracefully falls back to webview, so that it can be used in production ready usecases, ensuring a seamless user experience.
## Integration Guide: Bringing pwHtml Latex Into Your Project:
1) For new project system following has to be added to setting.gradle and for old system it has to be added to root level build.gradle
```
dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
........... other repo
mavenCentral()
maven("https://jitpack.io")
}
}
```
2) Then add the dependency to the app level build.gradle
```
dependencies {
implementation 'com.github.tech-pw:RenderX:$version'
}
```
