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
)
