I needs to upload images in my plugin and use wp.media for this task. According to https://codex.wordpress.org/Javascript_Reference/wp.media
Its work, but I needs to have "Select and Crop" option in media library after upload my image with custom size.
I was see this in default theme in appearence custom header image, but can't understand how I can use this in my plugin with wp.media js?
This my not be better solution but work in wordpress :) i use Thumbnail Crop Position and Simple Image Sizes for that :) Good luck! :)
