Public Constructors

	Name	Description
	JpegDecoder	Overloaded. Initializes a new instance of the class.

Public Properties

	Name	Description
	IsAuthenticationRequired	Gets a value indicating whether source document requres authentication. (Inherited from DecoderBase)
	IsDisposed	Gets a value indicating whether this decoder is disposed. (Inherited from DecoderBase)
	IsVectorDecoder	Gets a value indicating whether the decoder is a vector decoder. (Inherited from DecoderBase)
	Name	Gets the name of the decoder.
	PageCount	Gets the number of pages in the source file stream. (Inherited from DecoderBase)
	SourceStream	Gets the source stream of this decoder. (Inherited from DecoderBase)

Public Methods

	Name	Description
	Authenticate	Performs authentication using specified authentication request. (Inherited from DecoderBase)
	CanConvertToSvgOptimally	Determines whether this decoder can convert page with specified index to SVG optimally. (Inherited from DecoderBase)
	CanReadImageRegion	Determines that decoder can read a region of the image.
	CanUseProgressiveDecoding	Determines that decoder can progressively read the image.
	Close	Closes the source of the decoder.
	Dispose	Overloaded. Releases all resources used by the object. (Inherited from DecoderBase)
	GetAuthorizationResult	Returns the authorization result. (Inherited from DecoderBase)
	GetDefaultDecodingSettings	Returns the default decoding settings of the specified page.
	GetDefaultLayoutSettings	Returns the default layout settings of the document. (Inherited from DecoderBase)
	GetDefaultRenderingSettings	Returns the default rendering settings of the specified page. (Inherited from DecoderBase)
	GetDocumentMetadata	Returns a document metadata. (Inherited from DecoderBase)
	GetImage	Overloaded. Returns an image, which is associated with the specified page of image/document source. (Inherited from DecoderBase)
	GetImageInfo	Overloaded. Returns information about JPEG image without loading the image data into memory.
	GetImageRect	Returns a scaled rectangle of image.
	GetImageRectGrid	Returns an image grid as array of rectangles.
	GetImageRectScales	Returns an array of scale factors for rectangles of image grid.
	GetImageRegion	Returns a scaled region of image.
	GetPageMetadata	Returns a metadata of JPEG file.
	GetPrimaryDecoderName	Returns name of primary decoder (decoder that decodes image data) for specified page index. (Inherited from DecoderBase)
	GetRasterGridEditor	Returns the raster grid editor for image. (Inherited from DecoderBase)
	GetThumbnail	Overloaded. Returns a thumbnail image of the specified page of the image source.
	IsValidFormat	Determines that stream contains JPEG file.
	SetImageSize	Sets the size of the image. This method must be used when image size is not specified in JPEG stream because image size exceeds allowable image dimension (width/height) in 65535 pixels.

Protected Methods

	Name	Description
	CheckPageIndexValue	Checks the value of the page index. (Inherited from DecoderBase)
	CheckRenderingSettingsValue	Check the value of rendering settings. (Inherited from DecoderBase)
	Finalize	Allows an DecoderBase to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from DecoderBase)
	GetPageCount	Returns the number of pages in the source file stream. (Inherited from DecoderBase)
	OnPageCountChanged	Raises the [PageCountChanged] event. (Inherited from DecoderBase)
	PerformColorCorrection	Performs color correction using specified decoding settings. (Inherited from DecoderBase)
	SetPageCount	Sets the number of pages in the source file stream. (Inherited from DecoderBase)

Public Events

	Name	Description
	PageCountChanged	Occurs when page count is changed. (Inherited from DecoderBase)
