Detailed Description

This accessor creates a multi-tile composite of a single channel (and a single plane). The accessor will request all tiles that intersect with the specified ROI and are on the specified plane and create a composite as shown here:

The resulting output bitmap will look like this:

This accessor only operates on pyramid layer 0 - i. e. only sub-blocks with logical_size = physical_size will be considered. If the flag "drawTileBorder" is set, then the tiles will be sorted by their M-index (tiles with higher M-index are placed 'on top').
The pixel type of the output bitmap is either specified as an argument or it is automatically determined. In the latter case the first sub-block found on the specified plane is examined for its pixeltype, and this pixeltype is used.
The pixels in the output bitmap get converted from the source pixels (if their pixeltypes differ).

◆ Get() [1/5]

virtual std::shared_ptr<libCZI::IBitmapData> libCZI::ISingleChannelTileAccessor::Get	(	const libCZI::IntRect &	roi,
		const IDimCoordinate *	planeCoordinate,
		const Options *	pOptions
	)

pure virtual

Gets the tile composite of the specified plane and the specified ROI. The pixeltype is determined by examing the first subblock found in the specified plane (which is an arbitrary subblock). A newly allocated bitmap is returned.

It needs to be defined what is supposed to happen if there is no subblock found in the specified plane.

Parameters

roi	The ROI.
planeCoordinate	The plane coordinate.
pOptions	Options for controlling the operation.

Returns: A std::shared_ptr<libCZI::IBitmapData> containing the tile-composite.

◆ Get() [2/5]

std::shared_ptr<libCZI::IBitmapData> libCZI::ISingleChannelTileAccessor::Get	(	int	xPos,
		int	yPos,
		int	width,
		int	height,
		const IDimCoordinate *	planeCoordinate,
		const Options *	pOptions
	)

inline

Gets the tile composite of the specified plane and the specified ROI. The pixeltype is determined by examing the first subblock found in the specified plane (which is an arbitrary subblock). A newly allocated bitmap is returned.

Parameters

xPos	The x-position.
yPos	The y-position.
width	The width.
height	The height.
planeCoordinate	The plane coordinate.
pOptions	Options for controlling the operation.

Returns: A std::shared_ptr<libCZI::IBitmapData>

◆ Get() [3/5]

virtual void libCZI::ISingleChannelTileAccessor::Get	(	libCZI::IBitmapData *	pDest,
		int	xPos,
		int	yPos,
		const IDimCoordinate *	planeCoordinate,
		const Options *	pOptions
	)

pure virtual

Copy the tile composite into the specified bitmap. The bitmap passed in here determines the width and the height of the ROI (and the pixeltype).

Parameters

[in]	pDest	The destination bitmap.
	xPos	The x-position of the ROI (width and height are given by pDest).
	yPos	The y-position of the ROI ((width and height are given by pDest).
	planeCoordinate	The plane coordinate.
	pOptions	Options for controlling the operation.

◆ Get() [4/5]

virtual std::shared_ptr<libCZI::IBitmapData> libCZI::ISingleChannelTileAccessor::Get	(	libCZI::PixelType	pixeltype,
		const libCZI::IntRect &	roi,
		const IDimCoordinate *	planeCoordinate,
		const Options *	pOptions
	)

pure virtual

Gets the tile composite of the specified plane and the specified ROI.

Parameters

pixeltype	The pixeltype.
roi	The ROI.
planeCoordinate	The plane coordinate.
pOptions	Options for controlling the operation.

Returns: A std::shared_ptr<libCZI::IBitmapData> containing the tile-composite.

◆ Get() [5/5]

std::shared_ptr<libCZI::IBitmapData> libCZI::ISingleChannelTileAccessor::Get	(	libCZI::PixelType	pixeltype,
		int	xPos,
		int	yPos,
		int	width,
		int	height,
		const IDimCoordinate *	planeCoordinate,
		const Options *	pOptions
	)

inline

Gets the tile composite of the specified plane and the specified ROI.

Parameters

pixeltype	The pixeltype.
xPos	The x-position.
yPos	The y-position.
width	The width.
height	The height.
planeCoordinate	The plane coordinate.
pOptions	Options for controlling the operation.

Returns: A std::shared_ptr<libCZI::IBitmapData>
