Constructors
| RectF() |
Create a new empty RectF. |
| RectF(IntPtr, JniHandleOwnership) |
A constructor used when creating managed representations of JNI objects; called by the runtime. |
| RectF(Rect) | |
| RectF(RectF) |
Create a new rectangle, initialized with the values in the specified rectangle (which is left unmodified). |
| RectF(Single, Single, Single, Single) |
Create a new rectangle with the specified coordinates. |

Methods

| Clone() |
Creates and returns a copy of this |
| Contains(RectF) |
Returns true iff the specified rectangle r is inside or equal to this rectangle. |
| Contains(Single, Single) |
Returns true if (x,y) is inside the rectangle. |
| Contains(Single, Single, Single, Single) |
Returns true iff the 4 specified sides of a rectangle are inside or equal to this rectangle. i.e. is this rectangle a superset of the specified rectangle. |

| Dispose() | (Inherited from Object) |
| Dispose(Boolean) | (Inherited from Object) |
| Equals(Object) |
Compares this instance with the specified object and indicates if they are equal. (Inherited from Object) |
| GetHashCode() |
Returns an integer hash code for this object. (Inherited from Object) |
| Height() | |
| Inset(Single, Single) |
Inset the rectangle by (dx,dy). |
| Intersect(RectF) |
If the specified rectangle intersects this rectangle, return true and set this rectangle to that intersection, otherwise return false and do not change this rectangle. |
| Intersect(Single, Single, Single, Single) |
If the rectangle specified by left,top,right,bottom intersects this rectangle, return true and set this rectangle to that intersection, otherwise return false and do not change this rectangle. |
| Intersects(RectF, RectF) |
Returns true iff the two specified rectangles intersect. |
| Intersects(Single, Single, Single, Single) |
Returns true if this rectangle intersects the specified rectangle. |

calling one of the |
| NotifyAll() |
Causes all threads which are waiting on this object's monitor (by means
of calling one of the |
| Offset(Single, Single) |
Offset the rectangle by adding dx to its left and right coordinates, and adding dy to its top and bottom coordinates. |
| OffsetTo(Single, Single) |
Offset the rectangle to a specific (left, top) position, keeping its width and height the same. |
| ReadFromParcel(Parcel) |
Set the rectangle's coordinates from the data stored in the specified parcel. |
| Round(Rect) |
Set the dst integer Rect by rounding this rectangle's coordinates to their nearest integer values. |
| RoundOut(Rect) |
Set the dst integer Rect by rounding "out" this rectangle, choosing the floor of top and left, and the ceiling of right and bottom. |
| Set(Rect) |
Copy the coordinates from src into this rectangle. |
| Set(RectF) |
Copy the coordinates from src into this rectangle. |
| Set(Single, Single, Single, Single) |
Set the rectangle's coordinates to the specified values. |

Sets the Handle property. (Inherited from Object) |
| SetIntersect(RectF, RectF) |
If rectangles a and b intersect, return true and set this rectangle to that intersection, otherwise return false and do not change this rectangle. |

Swap top/bottom or left/right if there are flipped (i.e. left > right and/or top > bottom). |
| ToArray<T>() | (Inherited from Object) |
| ToShortString() |
Return a string representation of the rectangle in a compact form. |
| ToString() |
Returns a string containing a concise, human-readable description of this object. (Inherited from Object) |
