#28277 closed enhancement (fixed)

Add ability to apply image edits to custom image sizes

This patch allows developers to add custom image sizes to the "Edit Image" -> "Apply changes to:" setting so that image edits may be set to only affect a custom image size.

This can now be accomplished using the 'edit_custom_thumbnail_sizes' filter and passing it an array of 'Label' => 'size' elements.

And this is my first contribution so please go easy on me (administratively speaking)!

This would certainly fill a hole in the incomplete edit feature.

Updated patch fixes some issues with inappropriate use of translation functions, adds escaping, and updates the patch.

The original patch required a user to return an array of image sizes to use in custom size editing; I changed that so a value of 'true' can return the value of get_intermediate_image_sizes(), though it can be overridden to customize the values.

Not requiring a custom array does mean that we don't have any custom labels for the sizes, which was a benefit to passing a custom array; but also makes it harder to turn on.

To test:

  • This patch does not enable the feature; it adds a filter to enable it. Before applying the patch, you can switch the value $edit_custom_sizes = false; to true.
  • Go to edit a media item and select an option to apply sizes to.
  • Verify that the edits were applied to the expected sizes.

Thanks, @costdev! I'm going to go ahead and commit this. I'm still not 100% thrilled with the use of size keys for labels, but I think that can be tweaked during beta, if it's seen as necessary. Since this is all behind a filter, anyway, it's not going to have a profound impact on most users.
