Images are now playing a very important role in influencing online customers and encouraging them to buy the product. For engagement in an e-commerce store, images are the basic factor. In Magento 2, we can configure storefront images through the view.xml file.
If you are new to my article, I suggest you go through my previous article in tutorial series.
What is view.xml file?
Images are configured in view.xml file for storefront and can be changed in our theme as per our requirements.
Location in theme folder :
app/design/frontend/<vendor_name>/ ├── <theme_name>/ │ ├── etc/ │ │ ├── view.xml
By default, Luma’s view.xml belongs to vendor/magento/theme-frontend-luma/etc/view.xml.
Configure Image properties in view.xml
<media>
<images module="Magento_Catalog">
...
</images>
</media>Attributes used :
- id: Ids are unique image identifiers in any theme scope. ids are used in .phtml templates for defining the type and properties of images displayed in each particular location on a particular page
- type: Type of image is defined here. It can be,
- image – corresponds to the Base Image role.
- small_image – corresponds to the Small Image role.
- swatch_image – corresponds to the Swatch Image role.
- swatch_thumb – corresponds to the Swatch Image role.
- thumbnail – corresponds to the Thumbnail Image role.
Let’s have an example to change main image size of product detail page:
<media>
<images module="Magento_Catalog">
<image id="product_page_image_medium" type="image_type">
<width>650</width> <!-- Image width in px -->
<height>650</height> <!-- Image height in px -->
</image>
</images>
</media>There are few parameters used with image:
- height: specifies height in pixels of image which is used to resize the image.
- width: specifies the width in pixels of image which is used to resize the image
- constrain: If set to true, images that are smaller than required by the configuration, are not enlarged. Default value: true, Type: Boolean
- aspect_ratio: If set to true, the ratio of image width and height are not changed without image fragmentation. Default value: true, Type: Boolean
- frame: If set to true, the image is not cropped. The attribute is only applied in case the aspect_ratio is set to true. Default value: true, Type: Boolean
- transparency: If set to true, the transparent background of images is saved. It is set to false, images have a white background (by default). You can set the color for the background using the background parameter. Default value: true. Default value: true, Type: Boolean
- background: The color for the background of the image. Not applied to images with transparency, if transparency is set to true. Format: “[, ,]”, e.g.: “[255, 255, 255]”. Default Value: [255, 255, 255], Type: string
Note: Before applying background color, you need to change transparent value to false.For example,
<image id="category_page_grid" type="small_image">
<width>300</width>
<height>300</height>
<transparency>false</transparency>
<background>[245, 81, 66]</background>
</image>
After configuration, we need to resize image:
$ php bin/magento catalog:images:resize
$ php bin/magento cache:flush
Here are the predefined variables :
