In this hour, you looked at ImageViews and Bitmaps. You learned how ScaleType is used to change how images display in ImageViews and saw how rotation can be used in ImageViews. You learned about the Matrix class. You handled the display of an unrealistically large image by reading the dimensions of the bitmap before displaying it. You drew the word “Hello” on Canvas and displayed it in an ImageView to learn about the relationship between an ImageView, Canvas, and Bitmap. Picasso, an open source image library, was introduced.
