Below programs illustrate the Gmagick::getquantumdepth() function in PHP:

Program 1:
Original Image:

<?php

// Create new Gmagick object
$im = new Gmagick(
'https://media.geeksforgeeks.org/wp-content/uploads/geeksforgeeks-15.png');

// Using getquantumdepth function
print_r($im->getquantumdepth());

?>

Output:

Array ( [quantumDepthLong] => 16 
        [quantumDepthString] => Q16 
) 

Program 2:
Original Image:

<?php

$string = "Computer Science portal for Geeks!";

// Creating new image of above String
// and add color
$im = new Gmagick();
$draw = new GmagickDraw();

// Fill the color in image
$draw->setFillColor(new GmagickPixel('green'));

// Set the text font size
$draw->setFontSize(50);

$metrix = $im->queryFontMetrics($draw, $string);
$draw->annotation(0, 40, $string);
$im->newImage($metrix['textWidth'], $metrix['textHeight'],
        new GmagickPixel('white'));

// Draw the image
$im->drawImage($draw);
$im->setImageFormat('jpeg');

// Using getquantumdepth function
print_r($im->getquantumdepth());

?>

Output:

Array ( [quantumDepthLong] => 16 
        [quantumDepthString] => Q16 
)
