Best practices using the Image Service

Learn about the best practices for using the image service and more. Our goals are:

  1. Make sure every image is perfectly sized as needed
  2. Multiple sizes are provided for various use cases
  3. Labels and configs made by the editor (for example, setting a priority corner) are respected by the resizer

Base Class with Kit.Image

This tutorial inherits from the Custom.Hybrid.Razor14 or the Custom.Hybrid.RazorTyped base class.

This allows us to use Kit.Image to access an IScrub without having to use GetService<IImageService>.

As learned in the previous tutorials the img tag can be created out of URLs. The image service can also be used with Fields. The field will contain the URL as well as additional Metadata like the description or what part of the picture is important (the Crop-Anchor).

To get the most out of 2sxc and its image configuration options it's best to use the image object instead of URLs. By using the image configuration options, the settings can be easily retrieved from the corresponding image.

The Image Service offers multiple parameters for further customization of the images, such as the factor. The factor works as a resize multiplier for the image as for example (0.5).

Below you will find an example:

The picture tag contains multiple configurations of images, which are called recipes in our ecosystem. The browser then chooses the optimal configuration based on the given srcset. Using the .Recipe("") method from the image service, you can easily add more size variants of your images.

Below you will find an example:

Picture default recipe

By passing in the Field object, the picture tag will apply the alt text automatically. Unless your code specifies the imgAlt parameter, which would override any internal setting.
Because alt texts are not always defined in the settings, you can set a imgAltFallback to be used if the alt text is not defined.
