PixelRect 结构

Constructor which sets the initial values to the values of the parameters. Width and Height must be non-negative

Bottom Property - This is a read-only alias for Y + Height If this is the empty rectangle, the value will be negative infinity.

BottomLeft Property - This is a read-only alias for the Point which is at X, Y + Height If this is the empty rectangle, the value will be positive infinity, negative infinity.

BottomRight Property - This is a read-only alias for the Point which is at X + Width, Y + Height If this is the empty rectangle, the value will be negative infinity, negative infinity.

Gets the center point of the rectangle.

Empty - a static property which provides an Empty rectangle. X and Y are positive-infinity and Width and Height are negative infinity. This is the only situation where Width or Height can be negative.

Height - The Height component of the Size. This cannot be set to negative, and will only be negative if this is the empty rectangle, in which case it will be negative infinity. If this rect is Empty, setting this property is illegal.

Left Property - This is a read-only alias for X If this is the empty rectangle, the value will be positive infinity.

Location - The Point representing the origin of the Rectangle

Right Property - This is a read-only alias for X + Width If this is the empty rectangle, the value will be negative infinity.

Size - The Size representing the area of the Rectangle

Top Property - This is a read-only alias for Y If this is the empty rectangle, the value will be positive infinity.

TopLeft Property - This is a read-only alias for the Point which is at X, Y If this is the empty rectangle, the value will be positive infinity, positive infinity.

TopRight Property - This is a read-only alias for the Point which is at X + Width, Y If this is the empty rectangle, the value will be negative infinity, positive infinity.

Width - The Width component of the Size. This cannot be set to negative, and will only be negative if this is the empty rectangle, in which case it will be negative infinity. If this rect is Empty, setting this property is illegal.

X - The X coordinate of the Location. If this is the empty rectangle, the value will be positive infinity. If this rect is Empty, setting this property is illegal.

Y - The Y coordinate of the Location If this is the empty rectangle, the value will be positive infinity. If this rect is Empty, setting this property is illegal.

Contains - Returns true if the Point is within the rectangle, inclusive of the edges. Returns false otherwise.

Contains - Returns true if the PixelRect non-Empty and is entirely contained within the rectangle, inclusive of the edges. Returns false otherwise

Contains - Returns true if the Point represented by x,y is within the rectangle inclusive of the edges. Returns false otherwise.

Equals - compares this PixelRect with the passed in object. In this equality int.NaN is equal to itself, unlike in numeric equality. Note that int values can acquire error when operated upon, such that an exact comparison between two values which are logically equal may fail.

Equals - compares this PixelRect with the passed in object. In this equality int.NaN is equal to itself, unlike in numeric equality. Note that int values can acquire error when operated upon, such that an exact comparison between two values which are logically equal may fail.

Compares two PixelRect instances for object equality. In this equality int.NaN is equal to itself, unlike in numeric equality. Note that int values can acquire error when operated upon, such that an exact comparison between two values which are logically equal may fail.

Returns the HashCode for this PixelRect

Inflate - inflate the bounds by the size provided, in all directions If this is Empty, this method is illegal.

Inflate - inflate the bounds by the size provided, in all directions. If -width is > Width / 2 or -height is > Height / 2, this PixelRect becomes Empty If this is Empty, this method is illegal.

Inflate - return the result of inflating rect by the size provided, in all directions If this is Empty, this method is illegal.

Inflate - return the result of inflating rect by the size provided, in all directions If this is Empty, this method is illegal.

Intersect - Update this rectangle to be the intersection of this and rect If either this or rect are Empty, the result is Empty as well.

Intersect - Return the result of the intersection of rect1 and rect2. If either this or rect are Empty, the result is Empty as well.

IntersectsWith - Returns true if the PixelRect intersects with this rectangle Returns false otherwise. Note that if one edge is coincident, this is considered an intersection.

Offset - translate the Location by the offset provided If this is Empty, this method is illegal.

Offset - return the result of offsetting rect by the offset provided If this is Empty, this method is illegal.

Scale the rectangle in the X and Y directions

Creates a string representation of this object based on the current culture.

Creates a string representation of this object based on the IFormatProvider passed in. If the provider is null, the CurrentCulture is used.

Union - Update this rectangle to be the union of this and rect.

Union - Return the result of the union of rect1 and rect2.

Compares two PixelRect instances for exact inequality. Note that int values can acquire error when operated upon, such that an exact comparison between two values which are logically equal may fail. Furthermore, using this equality operator, int.NaN is not equal to itself.
