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(
// Raise the image. $gmagick ->raiseimage(12, 12, 12, 12, true);
header( 'Content-type: image/png' );
// Output the image echo $gmagick ;
?> |
Output:
<?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();
?> |
