Methods

Name	Description
static FromFile(string)	Creates an Image from the specified file.
static FromStream(Stream)	Creates an Image from the specified data stream.
static FromStream(Stream, bool)	Creates an Image from the specified data stream, optionally using embedded color management information in that stream.
Clone()	Creates an exact copy of this Image.
virtual Dispose()	Releases all resources used by this Image.
GetBounds(ref GraphicsUnit)	Gets the bounds of the image in the specified unit.
GetFrameCount(FrameDimension)	Returns the number of frames of the specified dimension.
abstract GetPropertyItem(int)	Gets the specified property item from this Image.
GetThumbnailImage(int, int, GetThumbnailImageAbort, IntPtr)	Returns a thumbnail for this Image.
abstract RemovePropertyItem(int)	Removes the specified property item from this Image.
abstract RotateFlip(RotateFlipType)	This method rotates, flips, or rotates and flips the Image.
Save(string)	Saves this Image to the specified file or stream.
Save(Stream, ImageFormat)	Saves this image to the specified stream in the specified format.
Save(string, ImageFormat)	Saves this Image to the specified file in the specified format.
Save(Stream, ImageCodecInfo, EncoderParameters)	Saves this image to the specified stream, with the specified encoder and image encoder parameters.
Save(string, ImageCodecInfo, EncoderParameters)	Saves this Image to the specified file, with the specified encoder and image-encoder parameters.
SaveAdd(EncoderParameters)	Adds a frame to the file or stream specified in a previous call to the one of Image.Save(…) methods. Use this method to save selected frames from a multiple-frame image to another multiple-frame image.
SaveAdd(Image, EncoderParameters)	Adds a frame to the file or stream specified in a previous call to the one of Image.Save(…) methods.
SelectActiveFrame(FrameDimension, int)	Selects the frame specified by the dimension and index.
abstract SetPropertyItem(PropertyItem)	Stores a property item (piece of metadata) in this Image.
static FromHbitmap(IntPtr)	Creates a Bitmap from a handle to a GDI bitmap.
static GetPixelFormatSize(PixelFormat)	Returns the color depth, in number of bits per pixel, of the specified pixel format.
static IsAlphaPixelFormat(PixelFormat)	Returns a value that indicates whether the pixel format for this Image contains alpha information.

Other Members

Name	Description
delegate GetThumbnailImageAbort	Provides a callback method for determining when the GetThumbnailImage method should prematurely cancel execution.
