Methods

	Name	Description
	AppendPage	This method appends one or more pages to the image file from the image file specified by the SrcImage parameter.
	Clear	This method clears the specified area of one or all pages in the image file.
	Convert2BW	This method can be used to convert one or more pages of the image file to black-and-white (bi-tonal, one-bit color depth).
	CreateMemoryBitmap	This method creates a MemoryBitmap object from one of the pages stored in the related ImageFile object.
	CreateMemoryBitmapArea	This method creates a MemoryBitmap object from a defined area in one of the pages specified by the Page parameter stored in the related ImageFile object.
	CreatePage	This method creates an empty page based on the information specified by the Info parameter.
	CreatePageFromBitmap	This method creates an empty page using the memory bitmap specified by the Bitmap parameter.
	DeletePage	This method deletes the page specified by the Page parameter from the image file.
	Deskew	This method de-skews a page by an amount given by the Slope parameter.
	Deskew3D	This method performs 3-dimensional de-skew on a page, which means it is used to correct the skew and perspective distortion that can occur when an image is taken by digital camera.
	Despeckle	This method performs adaptive noise removal on a B/W page.
	DetectSkew	This method attempts to detect the orientation and the slope of a page.
	Dispose	Releases all resources used by the ImageFile
	Equals	(Overrides Object.Equals(Object).)
	Format	This property returns the format of a page.
	GetEngine	Returns the Engine object.
	GetHashCode	(Overrides Object.GetHashCode().)
	GetPalette	This property is used to get or set the palette of an 8-bit page in the image file object.
	Info	This property creates and returns an ImageInfo object for the requested page of the image file.
	InsertPage	This method inserts one or more pages into the image file from the image file specified by the SrcImage parameter at the position specified by the Page parameter.
	Invert	This method inverts the specified area of one or all pages in the image.
	IsBlank	This method returns True if the page identified with the optional Page index parameter is a blank image.
	Pack	When this method is called the data from any pages deleted using ImageFile methods such as DeletePage are physically removed from the image file.
	Paletted	This method returns True if the requested page is a paletted, color one.
	RemoveLines	This method removes the vertical and horizontal lines from the specified part of a BW page and returns a RemovedLines collection containing the removed lines.
	Rotate	This method rotates one or more pages of the image file according to the Rotation parameter.
	SaveArea	This method saves a part of the page image to a new file using an image format specified by the Format parameter.
	SaveAs	This method saves the image to a new file using the specified format.
	SetPalette	This method sets the palette of an image's page.
	Transform	This method transforms one or more pages of the image file.
	TransformByMatrix	This method performs a geometric transformation on a page of the image file using the passed transformation matrix.
	TransformByPoints	This method performs a geometric transformation on a page.
	TransformPalette	This method transforms one or more pages of the image file.
	UpdatePage	This method updates a single page specified by the Page index parameter with a new image at the index SrcPage, stored in the image file defined by the SrcImage parameter.
	UpdatePageFromBitmap	This method replaces a page in the image file with the content specified by the Bitmap parameter.

Remarks

Use this object to get information on, manipulate or convert image files using a wide set of image manipulation methods. Most image-processing methods are available only for particular multi-page tiff images as documented in the descriptions for the methods concerned. To process other images using these methods, save them in the multi-page TIFF format first, perform the operations and convert them back to the original format.

The supported image resolution is in the range of 75-2400 dpi. When accessing bitmap pixel data, note that every stored image is stored in bottom-up line order and the pixel order is BGR.
