get-view

Gets the position and size of the visible region of a snip (in snip coordinates).

• (send a-wx:snip-admin get-view x y h w snip) -> void
      x : boxed inexact real or null
      y : boxed inexact real or null
      h : boxed inexact real or null
      w : boxed inexact real or null
      snip : wx:snip% object or null

  If snip is not null, the current visible region of the snip is installed in the boxes x, y, w, and w. The x and y values are relative to the snip's top-left corner.

  If snip is null, the total visible region of the snip's display is returned in buffer coordinates.
