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,使用Composer安装intervention/image库,代码如下:
composer require intervention/image:dev-master
编码,代码如下:
-
- <?php
- Route::pattern('width', '\d+');
- Route::pattern('height', '\d+');
- Route::get('{width}x{height}', 'ImageHolderController@getIndex');
-
- <?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)(www.111cn.net);
- $image = Image::canvas($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'));
- }
- }
