VichUploader 和 LiipImagine ：调整大小并保存上传的图像

Question

我正在做一个 symfony 项目，我正在使用 vichuploader 和 liipImagine，所以我想调整上传图片的大小并将它（调整后的图片）保存在上传目录中，以便用户上传图片最大 10Mb，然后调整大小以保持 100 KB 的大小。

到目前为止，我发现可以使用 imagine_filter 调整上传图片的大小，但在这种情况下，它会保留原始图片，并在缓存中创建调整大小的图片。

所以我试图做这样的事情：在我的控制器中

public function edit(Post $post,Request $request)
    {
        $form = $this->createForm(PostType::class, $post);
        $form->handleRequest($request);
        if ($form->isSubmitted() && $form->isValid()) {
            $this->em->flush();
            // And then resize all uploaded images...
            // All i know is to get the filename of each image stored in public/media/posts.
            // In loop because we allow multiple upload 
            // foreach ($post->getPictures() as $picture) {
            //   $picture->getFilename();
            // }
            $this->addFlash('success', 'ELement successfully modified');
            return $this->redirectToRoute('admin.post.index');
        }
        return $this->render('admin/post/edit.html.twig', [
            'post' => $post,
            'form' => $form->createView()
        ]);
    }

我的文章类型

class PostType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('title')
            ->add('category', EntityType::class, [
                'class' => Category::class,
                'required' => true,
                'choice_label' => 'title'
            ])
            ->add('pictureFiles', FileType::class, [
                'required' => false,
                'multiple' => true
            ])
            ->add('content')
        ;
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            'data_class' => Post::class,
        ]);
    }
}

感谢您的帮助！

由于找不到任何建议，我决定使用 InterventionImage。我知道这不是最好的做法，但是当你得不到你需要的东西时，你就会满足于你所拥有的。正如我上面所说，目标是在服务器上保留最小的图像并允许用户上传大图像。对于那些可能感兴趣的人，我添加了这个

public function edit(Post $post,Request $request)
    {
        $form = $this->createForm(PostType::class, $post);
        $form->handleRequest($request);
        if ($form->isSubmitted() && $form->isValid()) {
            $this->em->flush();
            $pics = [];
            foreach ($post->getPictures() as $picture) {
                // this path of the image
                $targetPath = 'media/posts/' .  $picture->getFileName();
                // and then resize it
                $this->resizeImage($targetPath);
            }
            dump($pics);
            $this->addFlash('success', 'ELement successfully modified');
            return $this->redirectToRoute('admin.post.index');
        }
        return $this->render('admin/post/edit.html.twig', [
            'post' => $post,
            'form' => $form->createView()
        ]);
    }

    private function resizeImage($targetPath)
    {
        $manager = new ImageManager(['driver' => 'gd']);
        $manager->make($targetPath)->widen(768, function ($constraint) {
            $constraint->upsize();
        })->save($targetPath);
    }

如果有其他改进的想法，我会注意的，谢谢:)
