Imagick Gradient

Note: (This is a fork from the imagickbutton, at https://github.com/chaoszcat/imagickbutton)

A beautifully PHP rendered imagick gradient (1px width) for used in rendering button backgrounds

Requirements

PHP 5.3 and Imagick extension installed. Installation steps is out of scope here. Google it, should have a lot of resources.

Example

To draw it:

$gradient = new Gradient();
$gradient->width(8)
         ->draw();

Quick Start

• Get the Gradient.php class file

• Include the Gradient.php in your script

    include 'Gradient.php';
    $gradient = new Gradient();
    $gradient->draw();
  

• That's it!

Configurations

These are the default properties in the Gradient class.

private $properties = array(
	'width' => 1,
	'height' => 40,
	'color' => '#ff6600',   //Gradient Color
	'glossy' => true,
	
	/**
	 * Image type. GIF genenerally produces smaller file.
	 * Supported gif/png.
	 */
	'imageType' => 'gif',
	
	/**
	 * Unless specified, these values will be automatically
	 * calculated based on buttonColor
	 */
	'startColor' => null,
	'endColor' => null
);

To set it, simply call the respective properties as a method. For example, a blueish gradient:

$gradient->gradientColor('#36a')
         ->draw();

A orange gradient (orangy color is the default color) with no glossy effect

$gradient->glossy(false)
         ->draw();

To read $_GET automatically, use readGET. Pass an array of whitelisted $_GET keys in array, or CSV string

$gradient->readGET(array('height', 'color'))
         ->draw();

To draw into a file instead, call this

$gradient->draw('path/to/the/file');
