RectangleF

RectangleF class

Represents a rectangular area of an image defined as single-precision floating point X and Y coordinates of its upper left corner and its width and height. This type should be allocated on stack and passed to functions by value or by reference. Never use System::SmartPtr class to manage objects of this type.

int GetHashCode() constReturns a hash code of the current object.
void Inflate(float, float)Increases the width and height of the rectangle represented by the current object, maintaining the location of the geometrical center of the rectangle. The width and height are increased in both directions by the specified amounts.
void Inflate(const SizeF&)Increases the width and height of the rectangle represented by the current object, maintaining the location of the geometrical center of the rectangle. The width and height are increased in both directions by the amounts specified by width and height values of the specified size object correspondingly.
static RectangleF Inflate(const RectangleF&, float, float)Increases the width and height of the rectangle represented by the specified object, maintaining the location of the geometrical center of the rectangle. The width and height are increased in both directions by the specified amounts.
void Intersect(const RectangleF&)Replaces the rectangle represented by the current object with the rectangle that results from the its intersection with the rectangle represented by the specified object.
static RectangleF Intersect(const RectangleF&, const RectangleF&)Returns a rectangle that is a result of intersection of the specified rectangles.
bool IntersectsWith(const RectangleF&)Determines if the rectangles represented by the current and specified objects intesect.
void Offset(const PointF&)Offsets the position of the rectangle represented by the current object by the specified amounts.
void Offset(float, float)Offsets the position of the rectangle represented by the current object by the specified amounts.
bool operator!=(std::nullptr_t) constAlways returns true.
bool operator==(std::nullptr_t) constAlways returns false.
RectangleF()Constructs a new instance of RectangleF object that represents a rectangle with X and Y coordinates and width and hegiht values set to 0.
RectangleF(float, float, float, float)Constructs a new instance of RectangleF object that represents a rectangle with the specified coordinates of its upper left corner and width and height.
RectangleF(const PointF&, const SizeF&)Constructs a new instance of RectangleF object that represents a rectangle with the coordinates of its upper left corner specified as an instance of PointF class and its width and height as an instance of SizeF class.
explicit RectangleF(const Rectangle&)Constructs a new instance of RectangleF object that represents the rectangle equivalent to the specified one.
