Problem:

Upload image files with Toolset Forms plugin, do some validation and modify the image.

Solution:

You can edit those specific forms, enable option "Use the WordPress Media Library manager for image, video, audio, or file fields"

So all files will be uploaded with WordPress Media Library manager,

Problem: I would like to know details about any APIs or event hooks available when uploading images in Forms with or without the new Media Library integration. I would like to have a developer create a custom image manipulation system where the User can crop and zoom the image before the Form is submitted.

Solution: There is no JavaScript API for forms, unfortunately, so there isn't much to offer on the front-end. Since Media Library support was integrated, the older AJAX image upload system no longer works in Forms. So the only APIs available are the Forms PHP APIs like cred_form_validate, cred_save_data, cred_success_redirect, and so on. These are all server-side events, so the Form must be submitted to trigger them. See the link here for more information about those APIs.
