imgToAdd	image with values to be added to imgDst (will not be modified)

◆ allocateImage() [1/3]

vtkSmartPointer< vtkImageData > allocateImage	(	int	vtkType,
		int const	dimensions[3],
		double const	spacing[3]
	)

Create a VTK image with the given properties.

Parameters

vtkType	the VTK type identifier (VTK_INT, VTK_UNSIGNED_CHAR, ...) for the voxel data type to use in the new image
dimensions	the size of the image in the 3 dimensions.
spacing	the spacing (distance of voxels) in each of the 3 dimension directions.

Returns: an image with a single component and the type, size and spacing as the given parameters, with allocated but uninitialized pixel data.

◆ allocateImage() [2/3]

vtkSmartPointer< vtkImageData > allocateImage	(	int	vtkType,
		int const	dimensions[3],
		double const	spacing[3],
		int	numComponents
	)

Create a VTK image with the given properties.

Parameters

vtkType	the VTK type identifier (VTK_INT, VTK_UNSIGNED_CHAR, ...) for the voxel data type to use in the new image
dimensions	the size of the image in the 3 dimensions.
spacing	the spacing (distance of voxels) in each of the 3 dimension directions.
numComponents	the number of components in each voxel.

Returns: an image with the type, size, spacing and number of components as the given parameters, with allocated but uninitialized pixel data.

◆ allocateImage() [3/3]

vtkSmartPointer< vtkImageData > allocateImage ( vtkSmartPointer< vtkImageData > img )

Create a VTK image that has the same properties (type, size, spacing) as the given image.

Parameters

img	image whose type, size and spacing will be used to create the result image; its data will not be copied over to the new image

Returns: an image that has the same type, size and spacing as the image given as parameter, with allocated but uninitialized pixel data.

◆ fillImage()

void fillImage	(	vtkSmartPointer< vtkImageData >	img,
		double const	value
	)

fill all pixels in the given image with the given value

Parameters

img	image to be filled
value	used to fill each voxel in given image

◆ isVtkIntegerImage()

bool isVtkIntegerImage ( vtkImageData * img )

Check whether the given image holds integer numbers.

Parameters

img	a VTK image

Returns: true if the values in the given VTK image are integer numbers, false if it holds floating point numbers

◆ mapReadableDataTypeToVTKType()

int mapReadableDataTypeToVTKType ( QString const & dataTypeName )

Maps a given data type string to the corresponding VTK type identifier.

Parameters

dataTypeName an entry from the list of readable data types (see readableDataTypeList())

Returns: the VTK type identifier (VTK_INT, VTK_UNSIGNED_CHAR, ...) for the given readable data type name, or -1 if the given name is not on the list

int mapRenderModeToEnum ( QString const & modeName )

◆ mapVTKTypeToReadableDataType()

QString mapVTKTypeToReadableDataType ( int vtkType )

Maps a given VTK type to the corresponding readable data type.

Parameters

vtkType the VTK type identifier (VTK_INT, VTK_UNSIGNED_CHAR, ...)

Returns: the name (in the list as returned by readableDataTypeList()) of the given VTK type identifier, or -1 if the given VTK type identifier is unknown

◆ mapVTKTypeToSize()

size_t mapVTKTypeToSize ( int vtkType )

Returns the size (in bytes) of the given VTK type.

Parameters

vtkType a VTK type identifier (VTK_INT, VTK_UNSIGNED_CHAR, ...)

Returns: the size in bytes of the given type (VTK_CHAR -> 1, ...), or 0 if it's an unknown type

◆ multiplyImage()

iAbase_API void multiplyImage	(	vtkSmartPointer< vtkImageData >	imgDst,
		double	value
	)

multiply all values of an image with the given value

Parameters

imgDst	the image to be multiplied
value	multiplier used for each voxel

◆ readableDataTypeList()

QStringList const & readableDataTypeList ( bool withLongLongTypes )

Returns a human-readable list of available data types for a single pixel/voxel.

Parameters

withLongLongTypes

◆ readImage()

void readImage	(	QString const &	filename,
		bool	releaseFlag,
		vtkSmartPointer< vtkImageData > &	ptr
	)

Read an image from disk into a VTK image.

Parameters

filename	the name of the file to read.
releaseFlag	whether the ITK release flag should be set on the ITK image reader
ptr	the smart pointer in which to store the loaded image (it will be assigned a new vtkImageData)

◆ RenderModeMap()

QMap< int, QString > const & RenderModeMap ( )

◆ setCamPosition()

void setCamPosition	(	vtkCamera *	cam,
		iACameraPosition	pos
	)

◆ storeImage()

void storeImage	(	vtkSmartPointer< vtkImageData >	img,
		QString const &	filename,
		bool	useCompression = `true`
	)

Stores an image on disk (typically in .mhd format).

Parameters

img	the image to store
filename	the name of the file to write to.
useCompression	whether the file should be compressed (.zraw) or not (.raw) in case we are storing .mhd files

◆ vtkStandardNewMacro()

vtkStandardNewMacro ( iAvtkImageData )

◆ writeSingleSliceImage()

void writeSingleSliceImage	(	QString const &	filename,
		vtkImageData *	img
	)

Write a single slice image to a common 2D picture format.

Parameters

filename	the name of the file to write to; this is expected to have an extension of tif, png, jpg or bmp; the type of the file written will be chosen according to this extension
img	the image to write; this already needs to be a 2D image (i.e., size in Z dimension = 1)
