# Colorizzar 

Change color of an image without lose alpha channel (alpha layer)  

Altere a cor da sua imagem sem perder a camada alpha (camada de transparência)

You can change the color of this [car](https://github.com/gabrieldarezzo/colorizzar/blob/master/car.png?raw=true) (Or any imagem you want), example:

Change color from [red](https://www.webpagefx.com/web-design/random-color-picker/#FF1F28) color pick by Hexadecimal to [blue](https://www.webpagefx.com/web-design/random-color-picker/#1F75FE):  

```php

setFromHex('#FF1F28');

// Will create 'blue.png' in new_cars/ folder

$changeColor->colorizeByNameColor('Blue', 'new_cars/');

```

Or create by specific color name, example from red to blue:  

```php

setFromHex('#FF1F28');

$changeColor->setToHex('#1F75FE');

// Will create 'blue.png' in new_cars/ folder

$changeColor->colorizeKeepAplhaChannnel('new_cars/blue.png');

```   

 

 

Result of   `colorizeKeepAplhaChannnel()`/`colorizeByNameColor()` :

![Scheme](doc/to_from_rgb.png)  

-----------

Create all `135` COLORS with `colorizeToAllColors()` !

Example of code:

```php

setFromHex('#FF1F28');

$changeColor->colorizeToAllColors('cars/');

```  

![Scheme](doc/to_from.png)  

### TODO-LIST:

  - FIX (ChangeColorTests.php:testColorizeLoopColors())  

  - FIX require_once() on tests, (Maybe a custom vendor.php for tests)    

  - Create a plugin in JS consume colorizzar and show in realtime result    

  - Improve tests (check in image created has new rgb expected)  

  - (almost done -> `ColorizzarWebService.php`) Create a WebService recive a file and manipulate methods to create dynamic  

  - (done) IMPROVE TODOLIST and update readme with new methods (hexadecimal)  

  - (done) Add DockBlock in all methods  

  - (done) Improve ChangeColor.php SOLID  

  - testExtensionIsFilePng()

#### ColorizzarWebService.php will be:   

  - Hash create by upload image  

  - create a folder with same name of hash  

  - result a JSON with all urls created    

JS-Plugin will consume ColorizzarWebService.php and show final result to user like a magic!
