This one works fine. Image is loaded into ImageView1.
Dim bmp As Image = fx.LoadImageSample(directory,fileName,300,200)

The best way to work with such images is by setting the ImageView gravity to Fill and resizing the ImageView based on the bitmap size.

You would need to first save the image in the imageview to a file, then you can use the LoadBitmapResize to load the image in from the file and return a different size bitmap.
