Class Rect


  • public class Rect
    extends Object
    Represents a rectangular region on the backing store. The edges of the rectangle are the infinitely thin region between adjacent pixels on the screen. The origin of the rectangle is its upper-left corner. It is inclusive of the pixels on the top and left edges and exclusive of the pixels on the bottom and right edges. For example, a rect at position (0, 0) and of size (1, 1) would include only the pixel at (0, 0).

    Negative coordinates and sizes are not supported, since they make no sense in the context of the packer, which deals only with positively sized regions.

    This class contains a user data field for efficient hookup to external data structures as well as enough other hooks to efficiently plug into the rectangle packer.

      • maxX

        public int maxX()
        Returns the maximum x-coordinate contained within this rectangle. Note that this returns a different result than Java 2D's rectangles; for a rectangle of position (0, 0) and size (1, 1) this will return 0, not 1. Returns -1 if the width of this rectangle is 0.
      • maxY

        public int maxY()
        Returns the maximum y-coordinate contained within this rectangle. Note that this returns a different result than Java 2D's rectangles; for a rectangle of position (0, 0) and size (1, 1) this will return 0, not 1. Returns -1 if the height of this rectangle is 0.
