: A Comprehensive Guide

Introduction

When generating PDFs using mPDF, it’s not uncommon to encounter issues where images seem to break free from their table cells (TDs). In this blog, we’ll explore the potential causes of this problem and provide various solutions with code examples.

1. Image Size and TD Width

Cause:

The image might be too large for the TD, causing overflow.

Solution:

Resize the image or ensure the TD has sufficient width.

<style>
   img {
      max-width: 100%;
      height: auto;
   }
</style>

2. CSS Styling Conflicts

Cause:

Conflicting CSS styles affecting the image or TD.

Solution:

Review and adjust your CSS styles.

<style>
   td, img {
      box-sizing: border-box;
   }
</style>

3. Padding and Margins

Cause:

Excessive padding or margins in the TD.

Solution:

Adjust padding and margins.

<style>
   td {
      padding: 10px;
      margin: 0;
   }
</style>

4. mPDF Configuration

Cause:

Issues with mPDF rendering.

Solution:

Check and adjust mPDF configuration settings.

$mpdf = new \Mpdf\Mpdf();
$mpdf->SetImportUse();

// Adjust image settings if needed
$mpdf->Image('path/to/image.jpg', 10, 10, 50);

5. HTML Structure

Cause:

Incorrect HTML structure.

Solution:

Ensure valid HTML structure.

<table>
   <tr>
      <td><img src="path/to/image.jpg" alt="Image"></td>
   </tr>
</table>

6. Image Alignment

Cause:

Improper image alignment settings.

Solution:

Set the image alignment.

<style>
   td img {
      display: block;
      margin: 0 auto;
   }
</style>

7. mPDF Version

Cause:

Outdated mPDF version.

Solution:

Update mPDF to the latest version.

composer require mpdf/mpdf

8. Image Format

Cause:

Unsupported image format.

Solution:

Convert to a widely supported format.

<img src="path/to/image.jpeg" alt="Image">

Conclusion

By addressing these potential issues step by step, you can overcome image overflow problems in mPDF. Remember to test thoroughly and adapt the solutions to your specific use case.
