v0.111.0

Added

• AvatarCropper (suggested by @Cyberistic in #240) — the photo can be zoomed out smaller than the outline. Until now it always
  had to cover the outline, which left no way to keep the whole of a wide photo, or a logo with
  margins, in a round avatar.
  • cover (default true) keeps the old behaviour. Set it to false to let the photo shrink.
  • minZoom (default 0.5) is how small it can get: its long side as a fraction of the
    outline's width.
  • background fills the space around a smaller photo, on screen and in the image crop()
    writes. It takes any colour or 'transparent', which is written as PNG, and defaults to the
    theme's background colour.
  • A crop with background in it needs the optional react-native-view-shot, because the image
    manipulator cannot pad an image on a phone. It is captured at the outline's on-screen
    resolution. A crop that is all photo still cuts the photo's own pixels.
