Gmagick is a PHP extension that lets you create, change, and get information
about images using the GraphicsMagick API. It includes the Gmagick,
GmagickDraw, and GmagickPixel classes.
Here's an example of how to use the Gmagick::getpackagename() function in PHP:
Original Image:
PHP Code:
<?php // Create new Gmagick object $im = new Gmagick( 'https://media.geeksforgeeks.org/wp-content/uploads/geeksforgeeks-15.png'); // Using getpackagename function echo $im->getpackagename(); ?>
Output:
GraphicsMagick
The list of complete Gmagick Functions are given below:

| Gmagick::implodeimage() | Creates a new image that is a copy of an existing image. |
| Gmagick::magnifyimage() | Scales an image to twice its original size. |
| Gmagick::medianfilterimage() | Applies a digital filter to improve the quality of a noisy image. |
| Gmagick::minifyimage() | Scales an image proportionally to half of its original size. |
| Gmagick::modulateimage() | Control the brightness, saturation, and hue of an image. |
| Gmagick::motionblurimage() | Simulates motion blur. |
| Gmagick::normalizeimage() | Enhances the contrast of a color image by adjusting the color of the pixels to span the entire range of colors available. |
| Gmagick::oilpaintimage() | Applies a special effect filter that simulates an oil painting. |
| Gmagick::raiseimage() | Creates a simulated three-dimensional button-like effect by lightening and darkening the edges of the image. |
| Gmagick::reducenoiseimage() | Sets smooth contours of an image while still preserving edge information. |
| Gmagick::resampleimage() | Resample the image to the desired resolution. |
| Gmagick::resizeimage() | Scales an image in given dimensions with a filter. |
| Gmagick::rollimage() | Rotates the image pixels by a specified number of degrees. |
| Gmagick::rotateimage() | Rotate an image by a specified number of degrees and fills the empty spaces with a given color. |
| Gmagick::scaleimage() | Scales the size of an image to the given dimensions. |
| Gmagick::setimageblueprimary() | Sets the blue primary point of the image. |
| Gmagick::setimagechanneldepth() | Sets the depth of a particular image channel. |
