What is PDF formatting and how to customize it in CodeIgniter?

PDF formatting refers to the style and layout of a PDF document, including text formatting, alignment, colors, fonts, and other visual elements. In CodeIgniter, you can customize PDF formatting by using a library or tool that allows you to generate and manipulate PDF files, such as TCPDF or FPDF.

To customize PDF formatting in CodeIgniter using TCPDF, you can follow these steps:

1. Download TCPDF library from the official website (https://tcpdf.org/) and extract the files to your CodeIgniter project directory.
2. Create a new controller in your CodeIgniter application and include the TCPDF library by adding the following code at the beginning of your controller file:

1

require_once('path/to/tcpdf/tcpdf.php');

1. In your controller method, you can customize the PDF formatting by setting various attributes such as font, font size, color, alignment, etc. Here is an example of how you can create a simple PDF document with customized formatting using TCPDF:

$pdf->AddPage();
$pdf->Cell(0, 10, 'Customized PDF Formatting', 0, 1, 'C');
$pdf->Output('example.pdf', 'D');

In this code snippet, we are creating a new TCPDF instance, setting the font to Helvetica, bold, and size 16, adding a new page, and then outputting the PDF file with the name 'example.pdf' and displaying it in the browser ('D').

1. You can further customize the PDF formatting by using TCPDF methods such as SetFont(), Cell(), SetTextColor(), SetFillColor(), SetDrawColor(), etc. Refer to the TCPDF documentation for more details on customization options.
