Output:
2 // which corresponds to one of imagick::RESOLUTION_PIXELSPERCENTIMETER.
Program 2:
<?php       // Create a new imagick object $imagick = new Imagick();       // Create a image on imagick object $imagick->newImage(500, 250, 'green');       // Create a new ImagickDraw object $draw = new ImagickDraw();       $draw->setClipUnits(imagick::RESOLUTION_PIXELSPERINCH);     $draw->setFontSize(24);     $draw->annotation(160, 125,                   'The clipUnits is '                  . $draw->getClipUnits() . '.');       // Render the draw commands $imagick->drawImage($draw);       // Show the output $imagick->setImageFormat('png'); header("Content-Type: image/png"); echo $imagick->getImageBlob(); ?> |
