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：

// 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)(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'));

    }

}
