Detailed Description

template<typename DATATYPE>
class ml::TSubImage< DATATYPE >

This template class manages/represents a rectangular 6d image region in memory which is organized linearly.

It inherits the functionality of SubImage and adds data type specific access functions to that class. Apart from the direct data access methods, there are the TSubImage::Cursor and TSubImage::ConstCursor classes, which allow to work on the typed data with cursor positioning/movements.

A const TSubImage can be used to only allow const access to the underlying image data.

Thread-safety: This class is reentrant.

This template class owns

all functionality from SubImage
methods query and set of (sub)image properties, which are inherited from the class ImageProperties (via SubImage).
a typed pointer to the memory chunk. The data type is given by the template parameter DATATYPE.
Access functions/methods for image data. Examples are
DATATYPE value;

ImageVector p(......); // Define coordinate

value = getImgVal(p); // Get voxel value from image

setImgVal(p,value); // Set value of voxel p in image

ml::TImageVector< MLint >

Notes: In the overloaded Module::calculateOutputSubImage, the Host passes untyped subimages (see SubImage). The image processing module usually needs to build typed wrappers around these untyped SubImages to have easy access to them. Then this class represents typed input tiles and output pages for image processing algorithms. Algorithms which have different typed input images can build easily template code to access the image data correctly. The methods to access image voxels are designed for image manipulation to be used by algorithm developers.

Constructor & Destructor Documentation

◆ TSubImage() [1/4]

template<typename DATATYPE >

ml::TSubImage< DATATYPE >::TSubImage	(	const SubImageBox &	box,
		MLDataType	dataType,
		void *	data )

inline

Constructor for an image region with location/extent box, with data type dataType (must fit to DATATYPE!) and the memory address data which hold the image region.

Note: The specification of dataType would usually not be necessary because it could be derived from DATATYPE. Anyway, one or two modules use differing DATATYPE and dataType for special purposes. Moreover, the derivation of dataType from template parameter DATATYPE is a little bit nasty, so we leave this constructor as it is. Note that this may be changed in future. Differing template data types and passed dataType enums will be handled as fatal error if real data is set.

References ML_BAD_DATA_TYPE, and ML_PRINT_FATAL_ERROR.

◆ TSubImage() [2/4]

template<typename DATATYPE >

ml::TSubImage< DATATYPE >::TSubImage ( )

inline

Default constructor to build a typed subimage (with an empty box) from scratch.

Initial values will be an empty SubImageBox as box, the ML data type is derived from the template type, and data is initialized to NULL. See also the documentation of TSubImage(const SubImageBox& box, MLDataType dataType, void* data).

◆ TSubImage() [3/4]

template<typename DATATYPE >

inline

Constructor to build a typed subimage from an untyped subImage.

See also the documentation of TSubImage(const SubImageBox& box, MLDataType dataType, void* data). NOTE: This does not take over the MemoryBlockHandle of the given subImage for performance reasons. You need to explicitly set the handle on the TSubImage if you want the TSubImage to reference count the data.

template<typename DATATYPE >

MLint ml::TSubImage< DATATYPE >::calculateMinMax	(	DATATYPE &	minValue,

		const SubImageBox *const	validBox = nullptr ) const

inline

Scans subimage and determines minimum and maximum values of the region which is part of subimage box and of validBox.

If no validBox is passed (default), all voxels are checked. The return value is the number of scanned voxels. If subimage is empty, minValue and maxValue are set to 0 and return value is 0. Warning: If used in calculateOutputSubImage take in consideration that the page may also contain invalid data which is not part of the image. Pass image box as validBox to be sure to access only valid regions.

template<typename FROM_DATATYPE >

void ml::TSubImage< DATATYPE >::copySubImageTyped	(	const TSubImage< FROM_DATATYPE > &	typedFromImg,
		const ScaleShiftData &	scaleShiftData )

inline

Copies image data from the subimage fromImg into the overlapping region of this subimage.

Grey values are transformed linearly according to the settings in scaleShiftData (see ScaleShiftData). Notes:

The copied data always has the data type of this subimage. If necessary it is cast.
By transforming voxel values linearly before copying them it is possible to avoid information loss due to type casting.
The default case of scaleShiftData defines scaleShiftData.getScale()==1 and scaleShiftData.getShift()==0. So voxel value transformation does not change anything and copying is implemented as special case which is therefore faster.

◆ fillBordersWithValue()

template<typename DATATYPE >

void ml::TSubImage< DATATYPE >::fillBordersWithValue	(	const SubImageBox &	box,

inline

Fills all regions with fillValue which are not covered by box.

Note that box must be specified in global image coordinates. So two subimages with different origins and same sizes are filled differently, dependent on their overlap with the box in global image coordinates. The cursor position is left undefined.
