PHP | Gmagick raiseimage() Function

The Gmagick::raiseimage() function is an inbuilt function in PHP which is used to create a simulated three-dimensional button-like effect by creating the lightning and darkening the edges of the image. The width and height of raise_info define the width of the vertical and horizontal edge of the effect. Syntax:

Gmagick Gmagick::raiseimage( $width, $height, $x, $y, $raise )

Parameters: This function accepts five parameters as mentioned above and described below:

• $width: This parameter stores the value of the width of the area to raise.
• $height: This parameter stores the value of the height of the area to raise.
• $x: This parameter stores the value of the x-coordinate.
• $y: This parameter stores the value of the y-coordinate.
• $raise: This parameter stores the value of the raise where value other than zero creates a 3-D raise effect, otherwise it has a lowered effect.

Return Value: This function returns Gmagick object on success. Errors/Exceptions: This function throws GmagickException on error. Below programs illustrates the Gmagick::raiseimage() function in PHP: Program 1: Input Image:

php

<?php

// Create a Gmagick object
$gmagick = new Gmagick(
'https://media.geeksforgeeks.org/wp-content/uploads/tech.png');

// Raise the image.
$gmagick->raiseimage(12, 12, 12, 12, true);

header('Content-type: image/png');

// Output the image
echo $gmagick;
?>

Output: Program 2:

php

<?php

// Create a GmagickDraw object
$draw = new GmagickDraw();

// Create GmagickPixel object
$strokeColor = new GmagickPixel('Red');
$fillColor = new GmagickPixel('Green');

// Set the color, opacity of image
$draw->setStrokeOpacity(1);
$draw->setStrokeColor('Red');
$draw->setFillColor('Green');

// Set the width and height of image
$draw->setStrokeWidth(7);
$draw->setFontSize(72);

// Function to draw circle
$draw->circle(250, 250, 100, 150);

$gmagick = new Gmagick();
$gmagick->newImage(500, 500, 'White');
$gmagick->setImageFormat("png");
$gmagick->drawImage($draw);

// Lower the image
$gmagick->raiseimage(102, 102, 102, 102, false);

// Display the output image
header("Content-Type: image/png");
echo $gmagick->getImageBlob();
?>
