在Laravel 5.2中调整图像大小 [英] Resize image in Laravel 5.2

问题描述

有人可以帮助我如何在Laravel中实现图像大小调整吗?

Can anyone help me how to implement resizing image in Laravel?

我只有这个代码:

if($request->hasFile('image')){
    if (Input::file('image')->isValid()) {
        $file = Input::file('image');
        $destination = base_path() . '/public/images/ServiceImages';
        $extension = Input::file('image')->getClientOriginalExtension();
        $fileName = rand(111,99999).'.'.$extension;

        if(!empty($data['Image'])){
            unlink($destination.$data['Image']);
        }

        $file->move($destination, $fileName);
        $service->image=$fileName;
    }
}

推荐答案

Laravel没有图像的默认调整大小.但是大多数Laravel开发人员在处理图像时会使用"图像干预".易于使用.

Laravel does not have a default resize of image. But most Laravel developers use 'Image intervention' in handling the image. It is easy to use.

要安装(图像干预):

STEP 1 运行

composer require intervention/image

第2步在您的config/app.php上:

STEP 2 On your config/app.php:

在$ providers数组中，添加以下内容:

In the $providers array, add the following:

Intervention\Image\ImageServiceProvider::class

在$ aliases数组中，添加以下内容:

In the $aliases array,add the following:

'Image' => Intervention\Image\Facades\Image::class

如果您的GD库缺少问题，请安装它

If you have problems your GD library is missing, install it

• PHP5:sudo apt-get install php5-gd
• PHP7:sudo apt-get安装php7.0-gd

要在您的控制器上使用.

To use on your controller.

第3步

在控制器之上

use Intervention\Image\ImageManagerStatic as Image;

第4步

关于您的方法(有几种方法，但这会给您一个想法)

On your method (there are several ways but this will give you an idea)

if($request->hasFile('image')) {

    $image       = $request->file('image');
    $filename    = $image->getClientOriginalName();

    $image_resize = Image::make($image->getRealPath());              
    $image_resize->resize(300, 300);
    $image_resize->save(public_path('images/ServiceImages/' .$filename));

}
