我有以下内容:

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use Imagine\Image\Box;
use Imagine\Image\ImageInterface;
use Imagine;

class UploadController extends Controller {

    public function processImage($request) {
        $file = $request->file('file');

        $path = '/images';
        $fileName = 'image.png';

        if ($file) {
            $file->move('../public' . $path, $fileName);
            $gThumb = $this->createThumbnail(219, 300, '../public/images', 'image', 'png', 'thumb', true);
            $pThumb = $this->createThumbnail(300, 300, '../public/images', 'image', 'png', 'pthumb');
            return response()->json([
                'gallery_thumbnail' => $path . '/' . $gThumb,
                'upload_thumbnail' => $path . '/' . $pThumb
            ]);
        }
    }

    function createThumbnail($height, $width, $path, $filename, $extension, $postfix = …

使用Laravel并尝试使用Imagine处理图像上传.

问题是我收到错误说明:

Imagine \ Exception \ RuntimeException

Imagick not installed
Open: /Applications/MAMP/htdocs/laravelcms/vendor/imagine/imagine/lib/Imagine/Imagick/Imagine.php

{
/**
* @throws RuntimeException
*/
public function __construct()
{
if (!class_exists('Imagick')) {
throw new RuntimeException('Imagick not installed');
}

我按照本指南,正确创建了所有文件夹和文件等,如下所述:

我还检查了Imagick文件夹,所有文件等都在正确的位置.

有帮助吗？

谢谢,克雷格.

I am using imagine library to create thumbnails for images. It is as simple as this.

$size = new \Imagine\Image\Box(240, 180);
$imagine->open($source_path)->thumbnail($size, 'inset')->save($target_path);

该库提供两种模式:插入和出站.在插入模式下,图像调整大小但不填充缩略图大小.所以我需要填充它来填充目标大小.有没有一种简单的方法来使用库函数？

我在yii2中得到了这段代码:

Image::thumbnail($path, 100, 100)->save($thumbnail, ['quality' => 50]);

我认为它将调整保持纵横比的原始图像的大小.但它只是创造了一个盒子......有什么可能是错的？

我使用的是 Symfony 2.3.*，当我使用 LiipImagineBundle 时，我在 app/logs/dev.log 中收到此错误。

request.CRITICAL: Uncaught PHP Exception Imagine\Exception\InvalidArgumentException: "png_compression_level option should be an integer from 0 to 9" at /vendor/imagine/imagine/lib/Imagine/Gd/Image.php line 535 {"exception":"[object] (Imagine\\Exception\\InvalidArgumentException: png_compression_level option should be an integer from 0 to 9 at /vendor/imagine/imagine/lib/Imagine/Gd/Image.php:535)"} []

有什么解决办法吗？谢谢

这是我的配置

liip_imagine:
    resolvers:
       default:
          web_path: ~
    filter_sets:
        cache: ~
        standard:
            quality: 200
            filters:
                thumbnail: { size: [400, 300], mode: outbound }
