下面我来给大家转一个关于Laravel4创建一个占位图片服务例子,有需要了解的朋友可看看。
使用Composer安装intervention/image库
composer require intervention/image:dev-master
编码
// vim app/routes.php
<?php Route::pattern('width', '\d+'); Route::pattern('height', '\d+'); Route::get('{width}x{height}', 'ImageHolderController@getIndex'); ?>
// vim app/controllers/ImageHolderController.php
<?php class ImageHolderController extends BaseController { public function getIndex($width, $height) { $width = intval($width); $height = intval($height); if ($width > 1900 || $height > 900) App::abort(404); $fontSize = min(max(intval($width / 5), 12), 38); $image = Image::canvas($width, $height, '#CCCCCC') ->line('#B5B5B5', 0, 0, $width, $height) ->line('#B5B5B5', $width, 0, 0, $height) ->text($width . 'x' . $height, $width / 2, $height / 2, function ($font) use ($fontSize) { $font->file(public_path('font/Georgia.ttf')); $font->align('center'); $font->valign('middle'); $font->size($fontSize); $font->color('#666666'); }); return Response::make($image, 200, array('Content-Type' => 'image/png')); } } ?>
