Simple to use Yii2 Framework extension for image manipulating using powerful Kohana Image Library. Inspired by old yii extension http://www.yiiframework.com/extension/image/ and Kohana Image Library https://github.com/kohana/image
{
"require":
{
"yurkinx/yii2-image": "dev-master"
}
}
In config file
/config/web.php
Add image component
'components' => array(
...
'image' => array(
'class' => 'yii\image\ImageDriver',
'driver' => 'GD', //GD or Imagick
),
)
$file=Yii::getAlias('@app/pass/to/file');
$image=Yii::$app->image->load($file);
header("Content-Type: image/png");
echo $image->resize($width,$height)->rotate(30)->render();Supported methods out of the box from Kohana Image Library:
$image->resize($width = NULL, $height = NULL, $master = NULL);
$image->crop($width, $height, $offset_x = NULL, $offset_y = NULL);
$image->sharpen($amount);
$image->rotate($degrees);
$image->save($file = NULL, $quality = 100);
$image->render($type = NULL, $quality = 100);
$image->reflection($height = NULL, $opacity = 100, $fade_in = FALSE);
$image->flip($direction);
$image->background($color, $opacity = 100);
$image->watermark(Image $watermark, $offset_x = NULL, $offset_y = NULL, $opacity = 100);Using resize with resize constrains
$image->resize($width, $height, \yii\image\drivers\Image::HEIGHT);
$image->resize($width, $height, \yii\image\drivers\Image::ADAPT)->background('#fff');Possible resize constrains:
// Resizing constraints ($master)
const NONE = 0x01;
const WIDTH = 0x02;
const HEIGHT = 0x03;
const AUTO = 0x04;
const INVERSE = 0x05;
const PRECISE = 0x06;
const ADAPT = 0x07;
const CROP = 0x08;Using flip with flipping directions
// Flipping directions ($direction)
$image->flip(\yii\image\drivers\Image::HORIZONTAL);Possible flipping directions:
const HORIZONTAL = 0x11;
const VERTICAL = 0x12;
