The Imagick::getQuantumDepth() function is an inbuilt function in PHP which is used to get the quantum depth of an Imagick object.
Syntax:
array Imagick::getQuantumDepth( void )
Parameters: This function does not accept any parameter.
Return Value: This function returns the Imagick quantum depth as a string.
Below programs illustrate the Imagick::getQuantumDepth() function in PHP:
Program 1:
Original Image:
<?php // Create new Imagick object $im = new Imagick(
// 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 Imagick();
$draw = new ImagickDraw();
// Fill the color in image $draw ->setFillColor( new ImagickPixel( '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 ImagickPixel( 'white' ));
// Draw the image $im ->drawImage( $draw );
$im ->setImageFormat( 'jpeg' );
// Using getQuantumDepth function print_r( $im ->getQuantumDepth());
?> |
Output:
Array ( [quantumDepthLong] => 16 [quantumDepthString] => Q16 )
