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( // 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(); ?> |
Output:
