Image brackground

[delyriand]

Preconditions

1. Magento 2.1.3
2. PHP 7

Steps to reproduce

1. Edit view.xml file
   ex: theme-frontend-luma/etc/view.xml
2. Add background color attribute to an image

<image id="related_products_list" type="small_image">
     <width>152</width>
     <height>230</height>
     <background>[250,247,247]</background>
</image>

3. Clear cache and reload images.

Expected result

1. Image with background

Actual result

1. Product image always has a black background
   

---

The problem comes from 2 methods:

• Method Magento\Catalog\Model\ImageExtractor::processImageBackground : The method return a string array
• Magento\Framework\Image\Adapter\AbstractAdapter::backgroundColor : If the color is not an integer, the background is ignored.
