VB.NET 1.1 Tutorial - GDI+ - Rectangle and RectangleF

Rectangle

A Rectangle structure stores a set of four integers that represent the location and size of a rectangle. A rectangle is defined by its width, height, and upper-left corner. By default, GDI+ will interpret the values entered as the amount of pixels on the screen.

There a two methods of creating a new Rectangle object.

Public Sub New( _
  ByVal location As Point, _
  ByVal size As Size _
)

This method initializes a new instance of the Rectangle class with the specified location and size.

• location - A Point that represents the upper-left corner of the rectangular region.
• size - A Size that represents the width and height of the rectangular region.

Public Sub New( _
  ByVal x As Integer, _
  ByVal y As Integer, _
  ByVal width As Integer, _
  ByVal height As Integer _
)

This method initializes a new instance of the Rectangle class with the specified location and size.

• x - The x-coordinate of the upper-left corner of the rectangle.
• y - The y-coordinate of the upper-left corner of the rectangle.
• width - The width of the rectangle.
• height - The height of the rectangle.

RectangleF

A RectangleF structure is only different to a Rectangle structure in the fact that floating point values are used instead of integers.

The two methods of creating a new RectangleF object are defined as:

Public Sub New( _
  ByVal location As PointF, _
  ByVal size As SizeF _
)

and

Public Sub New( _
  ByVal x As Single, _
  ByVal y As Single, _
  ByVal width As Single, _
  ByVal height As Single _
)
