izupet/laravel-flyimages
Composer 安装命令：
composer require izupet/laravel-flyimages
包简介
Optimize images on the fly for laravel
README 文档
README
Resize/crop image on the fly according to screen resolution (bootstrap grid pattern).
Prerequisite
Imagick (ImageMagick) PHP extension
PHP version >= 5.5
Laravel framework 4 and up
Installation
First you need to add this line to composer.json file:
{
"require": {
"izupet/laravel-flyimages" : "^1.0.0"
}
}
Update composer from the terminal:
$ composer update
Add service provider in app.php file:
Izupet\FlyImages\FlyImagesServiceProvider::class
After composer finishes its work, run this artisan command to generate config file
$ php artisan vendor:publish
Put this line of JavaScript to the <head> tag of your template.
<script>document.cookie='resolution='+Math.max(screen.width)+'; path=/';</script>
You are done.
Usage
Customize route in flyimages.php config file. This route will be used as a path to the images in your templates.
Now for every image you want to optimize you should append query string to the path. Possible parameters are:
lg-w lg-h md-w md-h sm-w sm-h xs-w xs-m
Valid values for this parameters are:
- number (integer) of pixels
- text (string) auto - calculate this dimension automatically according to opposite one (the ratio is kept)
If screen resolution is equal or higher than 1200px the lg prefixed parameters are used.
If screen resolution is equal or higher than 992px and smaller than 1200px the md prefixed parameters are used. If there are none, closest parent's one (lg) are used.
The same pattern of hierarchy is used also for sm and xs prefixed parameters.
A prerequisite for everything to work is that both width and height must be present for certain prefixed parameter. If there are not both present, original image will be delivered.
####Examples
<img src="/optimize/test.jpg?lg-w=400&lg-h=400&md-w=300&md-h=300"/> <img src="/optimize/test.jpg?lg-w=auto&lg-h=700"/> <img src="/optimize/test.jpg?sm-w=400&lg-h=400&md-w=300&xs-h=300"/> Wont work <div style="background-image:url('/optimize/test.jpg?sm-w=256&sm-h=256');"></div>
