The Imagick::getQuantumRange() function is an inbuilt function in PHP which is used to get the Imagick quantum range of an Imagick object.
Syntax:
array Imagick::getQuantumRange( void )
Parameters: This function does not accept any parameter.
Return Value: This function returns the associative array containing the quantum range.
Below programs illustrate the Imagick::getQuantumRange() function in PHP:
Program 1:
Original Image:
<?php // Create new Imagick object $im = new Imagick( // Using getQuantumRange function print_r( $im ->getQuantumRange()); ?> |
Output:
Array ( [quantumRangeLong] => 65535 [quantumRangeString] => 65535 )
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 getImageChannelDepth function // with different channel print_r( $im ->getQuantumRange()); ?> |
Output:
Array ( [quantumRangeLong] => 65535 [quantumRangeString] => 65535 )
