Gmagick::setimagebackgroundcolor() is a method in PHP's Gmagick extension that is used to set the background color of an image. This method takes a color value as input and sets it as the background color for the image.

The color value can be specified in various formats, such as hexadecimal RGB values (#RRGGBB), RGB values (rgb(r, g, b)), or color names (e.g., red, blue, green).

Here is an example demonstrating the usage of Gmagick::setimagebackgroundcolor():

php
<?php
// Create a new Gmagick object
$image = new Gmagick();

// Read an image file
$image->readImage('input.jpg');

// Set the background color to white
$image->setimagebackgroundcolor('white');

// Write the output image file
$image->writeImage('output.jpg');
?>


In this example, we create a new Gmagick object and read an input image file. We then use the setimagebackgroundcolor() method to set the background color to white. Finally, we write the modified image to an output file named 'output.jpg'.

This method is useful when you want to change the background color of an image before performing any operations or transformations on it.
