Scaling not working as expected

[LudoFarkas]

Describe the bug
Hi,

I'm migrating from Glide to Coil and have an issue with image scaling. I'm used to set the scale type in code. So in order to achieve ImageView.ScaleType = CENTER_CROP I set scale(Scale.FILL). The problem is that the image does not fill the ImageView, but fits entirely in. However, if the scale type is set in xml, it works as expected.

Expected behavior
I would like to get a clear explanation of how Coil's scale should work in case I don't understand it right. Or to have it corrected in case there is a bug.

To Reproduce
I have 2 ImageViews in a layout with blue background to highlight their borders (one of them without explicitly set scale type, the second set to centerCrop). The expected behavior is to achieve filling both of the ImageViews:

<androidx.appcompat.widget.LinearLayoutCompat
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:orientation="vertical">

    <androidx.appcompat.widget.AppCompatImageView
        android:id="@+id/thumbnail1ImageView"
        android:layout_width="200dp"
        android:layout_height="200dp"
        android:background="#19dbff" />

    <androidx.appcompat.widget.AppCompatImageView
        android:id="@+id/thumbnail2ImageView"
        android:layout_width="200dp"
        android:layout_height="200dp"
        android:layout_marginTop="20dp"
        android:background="#19dbff"
        android:scaleType="centerCrop" />
</androidx.appcompat.widget.LinearLayoutCompat>

The same image is loaded to them in code:

thumbnail1ImageView.load(File(photoPath)){
            scale(Scale.FILL)
}

thumbnail2ImageView.load(File(photoPath))

Only the second image fills the ImageView, see screenshots.

You should set the scale type on the ImageView. Coil will auto-detect the scale from the ImageView's scale type.

OK, but then for what use case should be scale(scale: Scale) used for?

I'm facing the same issue here. Have you got any answer?
