X = 37.8
Y = 37.8

Program 2:

$im = new Imagick();  
$draw = new ImagickDraw();  
    
// Fill the color in image  
$draw->setFillColor(new ImagickPixel('green'));  
    
// Set the text font size  
$draw->setFontSize(50);  
    
$matrix = $im->queryFontMetrics($draw, $string);  
$draw->annotation(0, 40, $string);  
$im->newImage($matrix['textWidth'], $matrix['textHeight'],  
         new ImagickPixel('white'));  
             
// Draw the image           
$im->drawImage($draw);  
$im->setImageResolution(50, 50);  
  
// getting Resolution of created image 
// using getimageresolution function 
$res = $im->getImageResolution(); 
echo "X = ".$res['x'] . "</br>"; 
echo "Y = ".$res['y'] ." </br>";
