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
)
