Android Question HugeImageView tile not showing at bottom

I try HugeImageView for B4A with my jpg file 2479 X 3209 in portrait and it run very well.

When I set I can zoom in but if I go to the bottom, a big portion of jpg is white, some part of image is lost. If I zoom out a full image reappears

I joint the same project as HugeImageView and added my jpg file and change to landscape.
