Below program illustrates the Gmagick::setimageresolution() function in PHP:
Program 1:
Original Image:
<?php $gmagick = new Gmagick( // Getting Resolution of image // using getimageresolution function $res = $gmagick->getImageResolution(); echo "X = ".$res['x'] . "</br>"; echo "Y = ".$res['y'] . "</br>"; // Function to set image resolution $gmagick->setimageresolution(50, 50); echo "After Set Resolution: </br>"; // Getting Resolution of image // using getimageresolution function $res = $gmagick->getImageResolution(); echo "X = " . $res['x'] . "</br>"; echo "Y = " . $res['y'] . "</br>"; ?> |
Output:
X = 37.8 Y = 37.8 After Set Resolution: X = 50 Y = 50
Program 2:
Original Image:
<?php $string = "Computer Science portal for Geeks!"; // Creating new image of above String // and add color and background $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); echo "Before: </br>"; // Getting Resolution of created image // using getimageresolution function $res = $im->getImageResolution(); echo "X = ".$res['x'] . "</br>"; echo "Y = ".$res['y'] ." </br>"; // Set image resolution (50, 50) $im->setimageresolution(50, 50); echo "After:</br> "; // Getting Resolution of created image // using getimageresolution function $res = $im->getImageResolution(); echo "X = ".$res['x'] . "</br>"; echo "Y = ".$res['y'] ." </br>"; ?> |
Output:
Before: X = 0 Y = 0 After: X = 50 Y = 50
