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 
  
// 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 
   
// 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(); 
?>
