ImageBuilder block override

[agiorgini]

Hello,

using 2.2.1 here. I need to override module-catalog/Block/Product/ImageBuilder.php block, so I did define my own:

<?php
namespace Hoop\Util\Block\Product;
use Mageno\Catalog\Helper\ImageFactory as HelperFactory;

class ImageBuilder {..}

but when I call it I get:

4 exception(s):
Exception #0 (Magento\Framework\Exception\LocalizedException): Invalid block type: Magento\Catalog\Block\Product\ListProduct
Exception #1 (ReflectionException): Class Hoop\Util\Block\Product\ImageFactory does not exist
Exception #2 (ReflectionException): Class Hoop\Util\Block\Product\ImageFactory does not exist
Exception #3 (RuntimeException): Source class "\Hoop\Util\Block\Product\Image" for "Hoop\Util\Block\Product\ImageFactory" generation does not exist.

ofc I want to use magento's ImageFactory, not redefine it.

what am I doing wrong?

Thanks a lot

I see the problem must be in the constructor:

public function __construct(
        HelperFactory $helperFactory,
        ImageFactory $imageFactory
    ) {
        //$this->helperFactory = $helperFactory;
        $this->imageFactory = $imageFactory;
    }

which I don't understand in the original magento block either, because in fact I can't find any ImageFactory inside Helper folder.

Any hint?

thanks

What do you want to do for ImageBuilder Class? Are you want to override or what need to do and please give a full details for your queru.

Hello Rakesh,

thanks for your answer. I need to override the create function, in order to fill the $data array with my own info, in particular the 'image_url' parameter will be filled with my own custom attribute.

thanks a lot

ok I found the solution myself:

<?php
class ImageBuilder extends \Magento\Catalog\Block\Product\ImageBuilder
{

    public function create()
    {
        /** @var \Magento\Catalog\Helper\Image $helper */
        $helper = $this->helperFactory->create()
            ->init($this->product, $this->imageId);

        $template = $helper->getFrame()
            ? 'Magento_Catalog::product/image.phtml'
            : 'Magento_Catalog::product/image_with_borders.phtml';

        $imagesize = $helper->getResizedImageInfo();

        $data = [
            'data' => [
                'template' => $template,
                'image_url' => $this->product->load($this->product->getId())->getMyCustomAttributeImage(),
                'width' => $helper->getWidth(),
                'height' => $helper->getHeight(),
                'label' => $helper->getLabel(),
                'ratio' =>  $this->getRatio($helper),
                'custom_attributes' => $this->getCustomAttributes(),
                'resized_image_width' => !empty($imagesize[0]) ? $imagesize[0] : $helper->getWidth(),
                'resized_image_height' => !empty($imagesize[1]) ? $imagesize[1] : $helper->getHeight(),
            ],
        ];

        return $this->imageFactory->create($data);
    }
}
