__construct()

public function __construct(?string $filename = null)

Description

Constructor for the Image module. Blocks direct URL access and checks for the GD extension. If a filename is provided, loads the image for immediate processing.

Note: The framework automatically instantiates Image via $this->image. You rarely need to call this constructor manually.

Parameters

Parameter	Type	Description	Default	Required
filename	string\|null	Path to an image file to load immediately. If null, no image is loaded.	null	No

Return Value

Type	Description
void	Constructor does not return a value.

Example Usage

PHP

<?php
// Automatic instantiation by framework (inside a controller)
class Products extends Trongate {
    public function edit() {
        // $this->image is automatically an Image instance
        $this->image->resize(800, 600);
    }
}

// Manual instantiation with pre-loading
$image = new Image('uploads/product.jpg');
$image->resize(300, 300);
