VB.net TreeView change images not resizing as expected

Hi

I am using the following code to resize the images in my TreeView
but as you can see in the image the hight seems to not change
possiblr because it is governed ny the row height.

How do I resolve this?

Thanks


        Dim myImageList As New ImageList()
        myImageList.Images.Add(Image.FromFile("C:\P1.png"))
        myImageList.Images.Add(Image.FromFile("C:\P2.png"))
        myImageList.Images.Add(Image.FromFile("C:\P3.png"))
        myImageList.ImageSize = New Size(100, 100)
