Syntax

public class Bitmap : Image

The Bitmap type exposes the following members.

Constructors

	Name	Description
	Bitmap(Stream)	Initializes a new instance of the Bitmap class from the specified data stream.
	Bitmap(String)	Initializes a new instance of the Bitmap class from the specified file.
	Bitmap(Image)	Initializes a new instance of the Bitmap class from the specified existing image.
	Bitmap(Int32, Int32)	Initializes a new instance of the Bitmap class with the specified size.
	Bitmap(Stream, Boolean)	Initializes a new instance of the Bitmap class from the specified data stream.
	Bitmap(String, Boolean)	Initializes a new instance of the Bitmap class from the specified file.
	Bitmap(Image, Size)	Initializes a new instance of the Bitmap class from the specified existing image, scaled to the specified size.
	Bitmap(Int32, Int32, PixelFormat)	Initializes a new instance of the Bitmap class with the specified size and format.
	Bitmap(Image, Int32, Int32)	Initializes a new instance of the Bitmap class from the specified existing image, scaled to the specified size.
	Bitmap(Int32, Int32, Int32, PixelFormat, Int32)	Initializes a new instance of the Bitmap class with the specified size and pixel data.
