Support Tagged Equations In Webbooks And EPUBs

Apr 2, 2025 by ADMIN 47 views

Introduction

In the world of academic publishing, equations play a crucial role in conveying complex mathematical concepts. However, when it comes to exporting equations with number tags in webbooks and EPUBs, the current implementation falls short. This article aims to explore the issue of tagged equations in webbooks and EPUBs, and propose a solution to restore support for these equations without compromising on the display size.

The Current State of Tagged Equations

Currently, equations with a number tag such as [latex]\tag{2.1}R\:=\frac{E}{I}[/latex] are displayed in PDF exports. However, when it comes to EPUBs, the same equation with a number tag does not display at all. This is a significant issue, as EPUBs are widely used for digital publishing and online courses.

On the other hand, webbooks do display the equation, but without the number tag on the right side. This is a compromise, but it is not ideal, as the number tag is an essential part of the equation.

The Importance of Tagged Equations

Tagged equations are essential in academic publishing, as they provide a clear and concise way to reference equations throughout a document. Without tagged equations, it can be difficult to navigate and understand complex mathematical concepts.

In addition, tagged equations are also important for accessibility. By providing a clear and concise way to reference equations, tagged equations can help readers with disabilities to better understand and engage with mathematical content.

The Solution

To restore support for tagged equations in webbooks and EPUBs, we need to modify the current implementation to include the number tag on the right side of the equation. This can be achieved by modifying the CSS styles to include the number tag in the equation display.

Here is an example of how the modified CSS styles could look:

.pb-mathjax .tag {
  display: inline-block;
  margin-left: 10px;
  font-size: 12px;
  color: #666;
}

This CSS style will display the number tag on the right side of the equation, while also ensuring that the equation is displayed in a clear and concise manner.

Implementation

To implement the solution, we need to modify the current implementation of webbooks and EPUBs to include the modified CSS styles. This can be achieved by modifying the pb-mathjax plugin to include the modified CSS styles.

Here is an example of how the modified pb-mathjax plugin could look:

function pb_mathjax_init() {
  // Include the modified CSS styles
  wp_enqueue_style( 'pb-mathjax', plugins_url( 'css/pb-mathjax.css', __FILE__ ) );
}

This modified plugin will include the modified CSS styles in the webbook and EPUB exports, ensuring that tagged equations are displayed correctly.

Testing and Validation

To ensure that the solution works correctly, we need to test and validate the implementation. This can be achieved by creating a test document with tagged equations and exporting it as a webbook and EPUB.

Here is an example of how the test document could look:

[latex]\tag{2.1}R\:=\frac{E}{}[/latex]

[latex]\tag{2.2}F\:=\frac{G}{H}[/latex]

This test document includes two tagged equations, which should be displayed correctly in the webbook and EPUB exports.

Conclusion

In conclusion, restoring support for tagged equations in webbooks and EPUBs is essential for academic publishing and online courses. By modifying the current implementation to include the number tag on the right side of the equation, we can ensure that tagged equations are displayed correctly in webbooks and EPUBs.

The solution proposed in this article is a simple and effective way to restore support for tagged equations, and it does not compromise on the display size. By implementing the modified CSS styles and modifying the pb-mathjax plugin, we can ensure that tagged equations are displayed correctly in webbooks and EPUBs.

Future Work

Future work on this project could include:

Improving the display of tagged equations in webbooks and EPUBs
Adding support for other types of equations, such as inline equations
Improving the accessibility of tagged equations for readers with disabilities

By continuing to work on this project, we can ensure that tagged equations are displayed correctly in webbooks and EPUBs, and that academic publishing and online courses continue to thrive.

Introduction

In our previous article, we explored the issue of tagged equations in webbooks and EPUBs and proposed a solution to restore support for these equations without compromising on the display size. In this article, we will answer some of the most frequently asked questions about supporting tagged equations in webbooks and EPUBs.

Q: What are tagged equations?

A: Tagged equations are equations that have a number tag attached to them, such as [latex]\tag{2.1}R\:=\frac{E}{I}[/latex]. These equations are essential in academic publishing and online courses, as they provide a clear and concise way to reference equations throughout a document.

Q: Why are tagged equations not displayed in EPUBs?

A: Tagged equations are not displayed in EPUBs because of a limitation in the current implementation of the pb-mathjax plugin. This plugin is responsible for rendering mathematical equations in webbooks and EPUBs, but it does not currently support tagged equations.

Q: How can I restore support for tagged equations in webbooks and EPUBs?

A: To restore support for tagged equations in webbooks and EPUBs, you need to modify the current implementation of the pb-mathjax plugin to include the modified CSS styles. This can be achieved by modifying the pb-mathjax plugin to include the modified CSS styles, as shown in the example code below:

function pb_mathjax_init() {
  // Include the modified CSS styles
  wp_enqueue_style( 'pb-mathjax', plugins_url( 'css/pb-mathjax.css', __FILE__ ) );
}
