Umbraco Image Crop Picker using Contentment Data List

A couple of weeks ago, Marcin Zajkowski and Adrian Ochmann announced the release of their new Umbraco package, Image Crop Picker.

The Image Crop Picker is a property-editor that enables a specific image crop to be selected from the configuration of a Image Cropper data-type. This can be useful for when a content-editor needs control over which crop is used for rendering an image.

The package has releases for both Umbraco v7 and v8, and has plans to extend the functionality in future releases. If it suits your needs, then please use it. 👍

Now what does this all have to do with my Contentment package? Since developing the Data List property-editor, whenever I see another package use a dropdown-list, checkbox-list or radiobutton-list, I can't shake the concept of separating the data-source from the list-editor.

So with the the Image Crop Picker package, I wondered - Could that be achieved as a custom Data Source? 🤔

It would need a way to select a pre-configured Image Cropper data-type, then get all the crop definitions from that data-type... Yeah, why not!

🕙🕚🕛 TL;DR, If you want to skip the explanation and see the code, it is available this gist: UmbracoImageCropDataListSource.cs

To do this, I needed to define the crops in my own Image Cropper data-type. I opted to copy Marcin's examples.

Next, once I had the code (from the gist) in place, I could create my custom Data List data-type.

The configuration for the data-source needs to select a pre-configured Image Cropper data-type.

For this UI, I opted to use the Item Picker editor, I thought it would be a nicer UI, in case have numerous Image Cropper data-types. This could have easily been done with a dropdown-list.

Once selected, you can configure the list-editor you would like to use. For this example, I chose a radiobutton-list.

You can then save the Data List data-type and add it to your document-type.

On your content page, it will be displayed like so...

Of course, if you prefer a different list-editor - say a dropdown-list, or enable multiple selections with a checkbox-list or Item Picker, you can do that.

Here is the Umbraco Image Crops data-source code in full...

If people think it would be interesting for me to break down and explain the code in more detail, please let me know. I'm happy to do so, just didn't want to do it unwarranted.


🔌 Plugs and begging... 🙏
