CGRect CGRect Struct
Definition
Structure defining a rectangle in terms of location and size.
[System.Serializable]
public struct CGRect : IEquatable<CoreGraphics.CGRect>type CGRect = struct- Inheritance
- Attributes
- Implements
Remarks
CGRects structures define a rectangle using floating point values of type nfloat and are defined using an initial location (X,Y) as well as a size (Width, Height).
You can save the CGRect into an NSDictionary by calling the ToDictionary() method. You can also get an CGRect out a serialized dictionary by using the TryParse(NSDictionary, CGRect) method.
Constructors

Methods
| Contains(CGPoint) Contains(CGPoint) |
Determines if the specified point is contained within this CGRect structure. |
| Contains(CGRect) Contains(CGRect) |
Determines if the rectangular region represented by |
| Contains(Double, Double) Contains(Double, Double) |
|
| Contains(nfloat, nfloat) Contains(nfloat, nfloat) |
Determines if the specified point is contained within this CGRect structure. |
| Contains(Single, Single) Contains(Single, Single) |
Determines if the specified point is contained within this CGRect structure. |
| Equals(Object) Equals(Object) |
Tests whether |
| Equals(CGRect) Equals(CGRect) |
Tests whether |
| FromLTRB(nfloat, nfloat, nfloat, nfloat) FromLTRB(nfloat, nfloat, nfloat, nfloat) |
Creates a CGRect structure with the specified edge locations. |
| GetHashCode() GetHashCode() |
Returns the hash code for this CGRect structure. For information about the use of hash codes, see |
| Inflate(CGSize) Inflate(CGSize) |
Enlarges this CGRect by the specified amount. |
| Inflate(Double, Double) Inflate(Double, Double) |
Increases the size of the rectangle by adding the specified amounts along both directions of each axis. |
| Inflate(nfloat, nfloat) Inflate(nfloat, nfloat) |
Enlarges this CGRect by the specified amount. |
| Inflate(Single, Single) Inflate(Single, Single) | |
| Inflate(CGRect, nfloat, nfloat) Inflate(CGRect, nfloat, nfloat) |

| Intersect(CGRect) Intersect(CGRect) |
Replaces this CGRect with the intersection of itself and the specified CGRect. |
| Intersect(CGRect, CGRect) Intersect(CGRect, CGRect) |
Returns a third CGRect structure that represents the intersection of two other CGRect structures. If there is no intersection, an empty CGRect is returned. |
| IntersectsWith(CGRect) IntersectsWith(CGRect) |
Determines if this rectangle intersects with |
| Offset(CGPoint) Offset(CGPoint) |
Adjusts the location of this rectangle by the specified amount. |
| Offset(Double, Double) Offset(Double, Double) |
Adjusts the location of this rectangle by the specified amount. |
| Offset(nfloat, nfloat) Offset(nfloat, nfloat) |
Adjusts the location of this rectangle by the specified amount. |
| Offset(Single, Single) Offset(Single, Single) |
Adjusts the location of this rectangle by the specified amount. |
| ToDictionary() ToDictionary() |
Serializes the state of the rectangle into an NSDictionary. |
| ToString() ToString() |
Gets the y-coordinate of the top edge of this CGRect structure. |
| TryParse(NSDictionary, CGRect) TryParse(NSDictionary, CGRect) | |
| Union(CGRect, CGRect) Union(CGRect, CGRect) |
Gets a CGRect structure that contains the union of two CGRect structures. |
