The ImagickDraw::skewY() function is an inbuilt function in PHP which is used to skews the current coordinate system in the vertical direction.
Syntax:
bool ImagickDraw::skewY( $degrees )
Parameters: This function accepts a single parameter $degrees which is used to hold the degrees to skew.
Return Value: This function does not return return any value.
Below programs illustrate the ImagickDraw::skewY() function in PHP:
Program 1:
<?php // require_once('path/vendor/autoload.php'); // Create an ImagickDraw object. $draw = new ImagickDraw();
// Set the image filled color $draw ->setFillColor( 'blue' );
$points = [[ 'x' => 40 * 5, 'y' => 10 * 5],
[ 'x' => 70 * 5, 'y' => 50 * 5],
[ 'x' => 60 * 5, 'y' => 15 * 5], ];
// Draw the polygon $draw ->polygon( $points );
// Set the image filled color $draw ->setFillColor( 'red' );
$draw ->skewY(-60);
$points = [[ 'x' => 40 * 5, 'y' => 10 * 5],
[ 'x' => 70 * 5, 'y' => 50 * 5],
[ 'x' => 60 * 5, 'y' => 15 * 5], ];
// Draw the polygon $draw ->polygon( $points );
// Set the image filled color $draw ->setFillColor( 'green' );
$draw ->skewY(30);
$points = [[ 'x' => 40 * 5, 'y' => 10 * 5],
[ 'x' => 70 * 5, 'y' => 50 * 5],
[ 'x' => 60 * 5, 'y' => 15 * 5], ];
// Draw the polygon $draw ->polygon( $points );
// Create new Imagick object $image = new Imagick();
// Set the image dimensions $image ->newImage(500, 500, 'white' );
// Set the image format $image ->setImageFormat( "png" );
// Draw the image $image ->drawImage( $draw );
header( "Content-Type: image/png" );
// Display the image echo $image ->getImageBlob();
?> |
Output:
Program 2:
<?php // require_once('path/vendor/autoload.php'); // Create an ImagickDraw object $draw = new ImagickDraw();
// Set the stroke color $draw ->setStrokeColor( 'black' );
// Set the image filled color $draw ->setFillColor( 'red' );
// Draw the circle $draw ->circle(250, 250, 100, 150);
// Set the image filled color $draw ->setFillColor( 'green' );
$draw ->skewY(-30);
// Draw the circle $draw ->circle(250, 250, 100, 150);
// Set the image filled color $draw ->setFillColor( 'yellow' );
$draw ->skewY(-60);
// Draw the circle $draw ->circle(250, 250, 100, 150);
// Create new Imagick object $image = new Imagick();
// Set the image dimensions $image ->newImage(700, 700, 'white' );
// Set the image format $image ->setImageFormat( "png" );
// Draw the image $image ->drawImage( $draw );
header( "Content-Type: image/png" );
// Display the image echo $image ->getImageBlob();
?> |
