Can you run a command to re-size only certain image types in Magento2?

Question

The below command will re-size all images based on new specified dimensions:

php bin/magento catalog:images:resize

Is there a variable to add to run for a certain image type only? For example, swatch or thumb only?

Answer 1

There is no straight forward answer to pass diff image types.

Because the way of doing resizing involves all the Themes, Stores, and Image types around 40-50 types (which are available in every theme file Namespace/Themename/etc/view.xml).

This runs for all the product images which will obviously consume more time.

One thing is to remove the unnecessary image tag from the etc/view.xml showing under <images module="Magento_Catalog"> from your respective theme files.

comment out below or other tag which does not active:

<image id="bundled_product_customization_page" type="thumbnail">
            <width>140</width>
            <height>140</height>
        </image>

Another way, there is one private method getViewImages is available in the file

Here, you can add a condition like in the foreach loop by overriding the preference to this file. This will surely reduce a lot of time.

//Only type = image will be proceed
if ($imageData['type'] !== 'image') {
    continue;
}

You can create custom cli tool based on ImageResizeCommand the acting below: https://github.com/magento/magento2/blob/2.3/app/code/Magento/MediaStorage/Console/Command/ImagesResizeCommand.php#L81

1. Create a custom cli tool by using this - https://devdocs.magento.com/guides/v2.4/extension-dev-guide/cli-cmds/cli-howto.html

2. In file Console\WhateverNameCommand.php, you can take the whole ImagesResizeCommand.php class from Magento.

   $themeId = 1; //Get this from theme table $themeObject = $this->themeModelFactory->create()->load($themeId); $this->resize->resizeFromThemes($themeObject);

Answer 2

This is related to v2.3.x

I would assume not, looking at the code of Magento 2 ImagesResizeCommand.

You might need to create a new custom module to override function execute() and possibly target information inside $resizeInfo[] array, for example filename.

(For example, you might create new custom arguments to the constructor in your module and target those conditions)

NOTE: I see the upcoming v2.4x version will be vastly different - functions like executeSync and executeASync will handle the execute() independently.
