Installation

You can install the package via Composer:

composer require nikkanetiya/laravel-color-palette

You must install the service provider (For Laravel < 5.5):

// config/app.php
'providers' => [
    ...
    NikKanetiya\LaravelColorPalette\ColorPaletteServiceProvider::class,
],

Register facade:

// config/app.php
'aliases' => [
    ...
    'ColorPalette' => NikKanetiya\LaravelColorPalette\ColorPaletteFacade::class,
],

Available Methods

1. getColor() - Use this method to get most dominant single color form image

   Example:

   // get most dominant color from image
   
   $color = ColorPalette::getColor( 'https://rawcdn.githack.com/nikkanetiya/laravel-color-palette/master/tests/images/strawberry.jpeg' );
   
   // Color provides several getters/properties
   echo $color;             // '#dc5550'
   echo $color->rgbString;  // 'rgb(220,85,80)'
   echo $color->rgbaString; // 'rgba(220,85,80,1)'
   echo $color->int;        // 14439760
   print_r($color->rgb);        // array(220, 85, 80) 
   print_r($color->rgba);       // array(220, 85, 80, 1)

   Options

   $color = ColorPalette::getColor($sourceImage, $quality = 10, $area = null );

   By default, getColor will have quality -> 10 and specific area -> null.

   • Quality can be int. 1 is the highest quality. There is a trade-off between quality and speed. The bigger the number, the faster the palette generation but the greater the likelihood that colors will be missed.
   • Area can be array|null $area[x,y,w,h]. It allows you to specify a rectangular area in the image in order to get colors only for this area. It needs to be an associative array with the following keys:
     • $area['x']: The x-coordinate of the top left corner of the area. Default to 0.
     • $area['y']: The y-coordinate of the top left corner of the area. Default to 0.
     • $area['w']: The width of the area. Default to image width minus x-coordinate.
     • $area['h']: The height of the area. Default to image height minus y-coordinate.

2. getPalette() - Use this method to find representative color palette form image.

   Example:

   // get colors from image
   
   $colors = ColorPalette::getPalette( 'https://github.com/nikkanetiya/laravel-color-palette/blob/master/tests/images/strawberry.jpeg' );
   
   foreach($colors as $color) {
       //
   }
   // Colors will be array of Color Objects

   Options

   $color = ColorPalette::getPalette($sourceImage, $colorCount = 10, $quality = 10, $area = null)

   • colorCount can be 2 to 256. It is the number of colors you want to retrieve for the image.
   • Quality & Area is same as above.
