Image source not readable in Laravel 5.2 - Intervention Image

问题

I have a small problem concerning the resizing process of a given image, I am trying to submit a form containing an input type -->file<-- I was able to upload a picture without resizing it, after that I decided to resize that image so I installed the Intervention Image Library using:

composer require intervention/image

then I integrated the library into my Laravel framework

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

and finally I configured it like following

php artisan vendor:publish --provider="Intervention\Image\ImageServiceProviderLaravel5"

my controller is like the following

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Input;
use Image; 

class ProjectController extends Controller{

public function project(Request $request){  


    $file = Input::file('file');
    $fileName = time().'-'.$file->getClientOriginalName();

    $file -> move('uploads', $fileName);
    $img=Image::make('public/uploads/', $file->getRealPath())->resize(320, 240)->save('public/uploads/',$file->getClientOriginalName());

}
}

but instead of resizing the pic the following exception is throwed

NotReadableException in AbstractDecoder.php line 302:
Image source not readable

回答1:

Shouldn't it be Image::make($file->getRealPath()) instead of Image::make('public/uploads/', $file->getRealPath())?

Image::make() doesn't seem to take two arguments, so that could be your problem.

Try this:

$file = Input::file('file');
$fileName = time() . '-' . $file->getClientOriginalName();

$file->move('uploads', $fileName);

$img = Image::make($file->getRealPath())
    ->resize(320, 240)
    ->save('public/uploads/', $file->getClientOriginalName());

Or if you want to do it without moving the file first, try this:

$file = Input::file('file');
$img = Image::make($file)
    ->resize(320, 240)
    ->save('public/uploads/', $file->getClientOriginalName());

In L5.2 its not directly possible to get image from Input facade. For that we need to first store the image on server and then give path into Image facade to do operations on image.

Code goes likes this:

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

        $destinationPath = public_path('uploads/user');
        $photoname = date("YmdHis");
        $file_extention = '.'.$request->file('picture')->getClientOriginalExtension();
        $photo = $photoname.$file_extention;
        $file_check = $request->file('picture')->move($destinationPath, $photo);

        $thumb_path = $destinationPath.'/thumbnail/'.$photo;

        $new_filePath =  $destinationPath.'/'.$photo;

        $assets_path = url('uploads/user/');

        $img = Image::make($assets_path.'/'.$photo)->fit(100)->save($thumb_path,40);

        $data['picture'] = $photo;           
    }

I was looking for direct solution i.e. as it was possible previously to take image directly from Input facade. If anyone of you have direct solution, show your code here and I'll reward you this bounty. Cheers.

Uploading a file and resizing it before saving is as easy as that: (Without validation or checks)

You can directly pass an instance of UploadedFile to InterventionImage::make()

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

    $filename = $file->getClientOriginalName();

    $img = \Image::make($file);
    $img->resize(320, 240)->save(public_path('uploads/'.$filename))

}

If you want to save original size and resized image:

    $img->save(public_path('uploads/'.$filename))
        ->resize(320, 240)
        ->save(public_path('uploads/thumb_'.$filename));

This was just tested on currently latest 5.2 version with is 5.2.45

[EDIT:]

If you call

$file->move();

Don't use

$file->getRealPath()

afterwards, because this will return false after calling move()

    $filename = $file->getClientOriginalName();
    $file->move('uploads', $filename);
    dd($file->getRealPath());

回答4:

This problem occurred when you resize the image after moving it

$file->move('uploads', $fileName);

$file->getRealPath() will return false after moving the image. You need to resize the image before the moving process. That's it ;)

$img=Image::make('public/uploads/', $file->getRealPath())->resize(320, 240)->save('public/uploads/',$file->getClientOriginalName());
$file->move('uploads', $fileName);
