CVApi
=====

[](#cvapi)

CVAPi library is built entirely in PHP to bring the power of computer vision into web development. Under the hood of CVAPi lies [OpenCV](https://opencv.org/), which is used extensively for computer vision applications.

Why use CVApi
-------------

[](#why-use-cvapi)

- Save your time by not having to worry about different versions and implementations of [OpenCV](https://opencv.org/)
- Easily integrate this API into any existing PHP Project, or use it in any popular framework such as [Laravel](https://laravel.com/) or [Symfony](https://symfony.com/)
- Our up-to-date documentation provides thorough instructions for each operations
- Computer Vision related heavy calculations are handled by our servers
- **...and many more**

Version Compatability
---------------------

[](#version-compatability)

- CVApi is compatible with PHP5.6 and above
- CVApi supports most image file extensions
- There are no known dependency conflicts

Getting Started
---------------

[](#getting-started)

Firstly, make sure you have Composer installed in your system. You can acquire it by clicking [here](https://getcomposer.org/)

After that, you can require CVAPi by writing out this command in terminal

```
$ composer require cv-api/cv-api
```

As Composer is done fetching necessary dependencies, make sure to register for an account in [CVApi](#)After the confirmation e-mail, open the **config** file inside **vendor/CVApi** and edit these settings

```
"public_key" => "your-public-key",
"secret_key" => "your-secret-key",
"password" => "your-password",
"path" => "your-path-to-storage"
```

In the end we can test whether CVApi is configured properly by trying out this piece of code

```
require_once __DIR__ . 'path_to_autoload_file.php';

use CVApi/CVApi;

CVApi::test();
```

If you receive the welcome message, you are good to go

Examples
--------

[](#examples)

Using CVApi is fairly straightforward. For example, we would like to save a grayscale version of our image. In order to do this you have to type:

```
CVApi::make(['old_image.jpg'])->grayscale()->results(function($new_image) { $new_image->save(); });
```

As we can see, all methods in CVApi are chainable. We can perform more than one operation at onceP

```
CVApi::make(['old_image.jpg'])
	->resize(300, 300)
	->brightness(85)
	->histogram(['B', 'G', 'R'])
	->results(function($new_images) {
		$new_images->save();
	->results(function($images) {
		$images->save();
});
```

CVApi is automatically configured to understand the source of the images. If we leave the **make** argument empty, CVApi automatically looks for images coming from form requests.

```
CVApi::make()->pyrDown(3)->results(function($image) { $image->save(); });
```
