Comment appliquer la transformation de la bibliothèque Glide? [Android Studio]

Question

J'ai une image dans un ImageView chargé de la galerie de mon téléphone et je veux appliquer certaine transformation Glide

Le code doit être comme ça

Glide.with(MainActivity.this) 
    .load(current image) 
    .bitmapTransform(new CropCircleTransformation(MainActivity.this)) 
    .into(myimageview); 

Mon problème est de savoir comment pour obtenir le Bitmap, drawable, uri etc (tout ce qui fonctionne) de myimageview à ".load" cela, donc Glide sait que c'est l'image qu'il va transformer ".into"myimageview.
