So I learned how to use planing to load images from the server and convert them and it works great.
But now, I want to know how can I use the same transformations on the image that I set in the ImageView before setting it as src?
You can use it in the same way as for images from the server Glide.with(context).load(uri).transform(new Transform()).into(view) , where uri is your local uri of the image and Transform is your transform class.
Glide.with(context).load(uri).transform(new Transform()).into(view)
