README

一个将图片调整大小并存储在缓存文件夹中的Yii2组件

安装

安装此扩展的首选方式是通过 composer。

• 运行以下命令之一

php composer.phar require "petersonsilvadejesus/yii2-image-resize" "*"

或者

"petersonsilvadejesus/yii2-image-resize" : "*"

将以下内容添加到您的应用 composer.json 文件的 require 部分。

• 在您的应用配置文件的 components 部分添加一个新的组件，例如

'components' => [
    'imageresize' => [
		'class' => 'petersonsilvadejesus\imageresize\ImageResize',
		//path relative web folder. In case of multiple environments (frontend, backend) add more paths 
		'cachePath' =>  ['assets/images', '../../frontend/web/assets/images'],
		//use filename (seo friendly) for resized images else use a hash
		'useFilename' => true,
		//show full url (for example in case of a API)
		'absoluteUrl' => false,
	],
],

使用方法

如果您想要获取图片URL

/*
 * $sImageFilePath_id: (required) path to file
 * $width/$height: (required) width height of the image
 * $mode: "outbound", "inset" or "{horz}:{vert}" where {horz} is one from "left", "cetrer", "right" and {vert} is one from "top", "center", "bottom"
 * $$quality: (1 - 100)
 * $chosenFileName: if config -> components -> imageresize -> useFilename is true? its an option to give a custom name else use original file name
 */
\Yii::$app->imageresize->getUrl($sImageFilePath, $width, $height, $mode, $quality, $chosenFileName);
