Return Value: This function does not returns any value.
Below programs illustrates the ImagickDraw::rotate() function in PHP:
Program 1:
<?php // require_once('path/vendor/autoload.php'); // Create an Imagick Draw object $draw = new \ImagickDraw(); // Set the stroke color $strokeColor = new \ImagickPixel( 'Green' ); // Set the fill color $fillColor = new \ImagickPixel( 'Red' ); // Set the stroke opacity $draw ->setStrokeOpacity(1); // Set the stroke color $draw ->setStrokeColor( 'Green' ); // Set the Fill Color $draw ->setFillColor( 'Red' ); // Set the stroke width $draw ->setStrokeWidth(2); // Draw the rectangle $draw ->rectangle(100, 200, 500, 400); // Set the stroke color $draw ->setStrokeColor( 'black' ); // Set the fill color $draw ->setFillColor( 'lightgreen' ); // Set the rotation $draw ->rotate(10); // Draw the rectangle $draw ->rectangle(100, 200, 500, 400); //Create an imagick object $imagick = new \Imagick(); // Set the image dimensions $imagick ->newImage(600, 500, 'White' ); // Set the image format $imagick ->setImageFormat( "png" ); // Draw the image $imagick ->drawImage( $draw ); header( "Content-Type: image/png" ); // Display the image echo $imagick ->getImageBlob(); ?> |
Output:
Program 2:
