In this tutorial, we will explain to you how to create and upload Grayscale Image with example in laravel 8. If you want to create a greyscale image from an original image in your laravel application then you can create using “intervention/image” package.

We will also explain in laravel 8 create and upload grayscale image with example. so you can also learn and use of laravel intervention image package.

So let’s start the creation of a greyscale image with the following steps.

Overview

Step 1: Install Laravel

Step 2: Install intervention/image Package

Step 3: Add providers and aliases

Step 4: Create Route

Step 5: Create a Controller

Step 6: Create Blade Files

Step 7: Run Our Laravel Application

Step 1: Install Laravel

We are going to install laravel 8, so first open the command prompt or terminal and go to xampp htdocs folder directory using the command prompt. after then run the below command.

composer create-project --prefer-dist laravel/laravel laravel8_image

1	composer create-project --prefer-dist laravel/laravel laravel8_image

Step 2: Install intervention/image Package

Now, We will install intervention/image package using below command.

composer require intervention/image

1	composer require intervention/image

Step 3: Add providers and aliases

We will add below providers and aliases in the “config/app.php” file.

'providers' => [
	....
	'Intervention\Image\ImageServiceProvider'
],
'aliases' => [
	....
	'Image' => 'Intervention\Image\Facades\Image'
]

'providers' => [

....

'Intervention\Image\ImageServiceProvider'

'aliases' => [

....

'Image' => 'Intervention\Image\Facades\Image'

]

Step 4: Create Route

Add the following route code in the “routes/web.php” file.

<?php
use App\Http\Controllers\ImageController;

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
Route::get('/', function () {
   // return view('welcome');	
});
Route::get('gray-scale-image', [ImageController::class, 'index']);
Route::post('gray-scale-image', [ImageController::class, 'grayScaleSaveImage'])->name('gray.scale.image');
?>

<?php

use App\Http\Controllers\ImageController;

|--------------------------------------------------------------------------

| Web Routes

|--------------------------------------------------------------------------

| Here is where you can register web routes for your application. These

| routes are loaded by the RouteServiceProvider within a group which

| contains the "web" middleware group. Now create something great!

Route::get('/', function () {

// return view('welcome');

});

Route::get('gray-scale-image', [ImageController::class, 'index']);

Route::post('gray-scale-image', [ImageController::class, 'grayScaleSaveImage'])->name('gray.scale.image');

Step 5: Create a Controller

Here below command help to create the controller and model.

php artisan make:controller ImageController

1	php artisan make:controller ImageController

ImageController.php

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use Image;
class ImageController extends Controller
{
  
    public function index()
    {
      return view('viewGrayscaleImage');
    }
    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function grayScaleSaveImage(Request $request)
    {
      $this->validate($request, [
        'title' => 'required',
            'imagefile' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
        ]);
        $image = $request->file('imagefile');
        $input['image_name'] = time().'.'.$image->getClientOriginalExtension();
        $destinationPath = public_path('/uploads');
        $img = Image::make($image->getRealPath());
        $img->greyscale()->save($destinationPath.'/'.$input['image_name']);
        return back()
          ->with('success','Image Uploaded successfully.')
          ->with('image_name',$input['image_name']);
    }
}

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;

use Image;

class ImageController extends Controller

{

public function index()

{

return view('viewGrayscaleImage');

}

/**

* Show the form for creating a new resource.

* @return \Illuminate\Http\Response

public function grayScaleSaveImage(Request $request)

{

$this->validate($request, [

'title' => 'required',

'imagefile' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',

]);

$image = $request->file('imagefile');

$input['image_name'] = time().'.'.$image->getClientOriginalExtension();

$destinationPath = public_path('/uploads');

$img = Image::make($image->getRealPath());

$img->greyscale()->save($destinationPath.'/'.$input['image_name']);

return back()

->with('success','Image Uploaded successfully.')

->with('image_name',$input['image_name']);

}

Step 6: Create Blade Files

Finally, We will create a viewGrayscaleImage.blade.php file in the “resources/views/” folder directory and paste the below code.

viewGrayscaleImage.blade.php

<html lang="en">
<head>

  <meta name="csrf-token" content="{{ csrf_token() }}">
</head>
<body>
<div class="container" style="margin: 50px;">
<h1>Laravel5 create and upload Grayscale Image </h1>
@if (count($errors) > 0)
  <div class="alert alert-danger">
    <strong>Whoops!</strong> There were some problems with your input.<br><br>
    <ul>
      @foreach ($errors->all() as $error)
        <li>{{ $error }}</li>
      @endforeach
    </ul>
  </div>
@endif
@if ($message = Session::get('success'))
<div class="alert alert-success alert-block">
  <button type="button" class="close" data-dismiss="alert">×</button>  
    <strong>{{ $message }}</strong>
</div>
<div class="row">
  <div class="col-md-4">
    <strong>Grayscale Image:</strong>
    <br/>
    <img src="{{ asset('uploads/'.Session::get('image_name')) }}" width="500px" />
  </div>
</div>
@endif
{{ Form::open(array('route' => 'gray.scale.image','enctype' => 'multipart/form-data')) }}
  <div class="row">
    <div class="col-md-4">
      <strong>Give a Title:</strong>
      {{ Form::text('title', null,array('class' => 'form-control','placeholder'=>'Give a title')) }}
    </div>
    <div class="col-md-12">
      <strong>Upload Image:</strong>
      {{ Form::file('imagefile', array('class' => 'image')) }}
    </div>
    <div class="col-md-12">
      <br/>
      <button type="submit" class="btn btn-success">Upload</button>
    </div>
  </div>
{{ Form::close() }}
</div>
</body>
</html>

<head>

<title>Laravel 8 create and upload Grayscale Image with example - XpertPhp </title>

</head>

<body>

<h1>Laravel5 create and upload Grayscale Image </h1>

@if (count($errors) > 0)

<strong>Whoops!</strong> There were some problems with your input.<br><br>

<ul>

@foreach ($errors->all() as $error)

<li>{{ $error }}</li>

@endforeach

</ul>

</div>

@endif

@if ($message = Session::get('success'))

<strong>{{ $message }}</strong>

</div>

<strong>Grayscale Image:</strong>

<br/>

</div>

@endif

{{ Form::open(array('route' => 'gray.scale.image','enctype' => 'multipart/form-data')) }}

<strong>Give a Title:</strong>

{{ Form::text('title', null,array('class' => 'form-control','placeholder'=>'Give a title')) }}

</div>

<strong>Upload Image:</strong>

</div>

<br/>

<button type="submit" class="btn btn-success">Upload</button>

</div>

</body>

</html>

Step 7: Run Our Laravel Application
We can start the server and run this example using the below command.

php artisan serve

1	php artisan serve

Now we will run our example using the below Url in the browser.

http://127.0.0.1:8000/gray-scale-image

1	http://127.0.0.1:8000/gray-scale-image
