Yii2 框架图像处理扩展。
从 yurkinx/yii2-image 分支而来

安装

添加到你的 composer.json 文件

"require": 
{
    "mervick/yii2-image": "~1.0"
}

之后执行 php composer.phar update

使用方法

简单

$driver = \mervick\image\drivers\GD::classname(); // or `\mervick\image\drivers\Imagick::classname()`
/* @var $image \mervick\image\Image */
$image = \mervick\image\Image::load('@path/to/file', $driver);
$image->resize($width, $height, 'crop');
$image->save(); 
// or $image->save('@path/to/file2.png', $quality);

使用组件

在 main.php 中配置

'components' => [
    'image' => [
        'class' => 'mervick\\image\\Component',
        'driver' => 'mervick\\image\\drivers\\Imagick',
    ],
],

使用

/* @var $image \mervick\image\Image */
$image = Yii::$app->image->load('@path/to/file');
$image->flip('vertical')->save('@path/to/file2.jpeg', $quality);

 * Fill the background color of the image.
 * @param string $color Hexadecimal color
 * @param integer $opacity Background opacity: 0-100
 * @return Image
 */
public function background($color, $opacity = 100);

/**

/**
 * Render the image.
 * @param string|null $type
 * @param integer|null $quality
 * @return string binary string

图像常量

    // resize contants
    const WIDTH   = 'width';
    const HEIGHT  = 'height';
    const AUTO    = 'auto';
    const INVERSE = 'inverse';
    const PRECISE = 'precise';
    const ADAPT   = 'adapt';
    const CROP    = 'crop';
    
    // Flipping constants 
    const HORIZONTAL = 'horizontal';
    const VERTICAL   = 'vertical';
