i recently bought your extension. I would like to know if i want to add some preprocessings to the image once the customer upload the image via the designer, where should i paste my code?
I have created a ticket in our support system for the developer to answer.
I had the same question as Johnny. This was the supports response:
There is a grayscale filter, however there is no way of applying that automatically. You'd have to develop your own solution for that.
