The Gmagick::getquantumdepth() function is an inbuilt function in PHP which is used to return the quantum depth of Gmagick object.
Syntax:
public Gmagick::getquantumdepth( void ) : array
Parameters: This function does not accept any parameter.
Return Value: This function returns the Gmagick quantum depth as string.
Below programs illustrate the Gmagick::getquantumdepth() function in PHP:
Program 1:
Original Image:
<?php   // Create new Gmagick object $im = new Gmagick(   // Using getquantumdepth function print_r($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
)
