On each axis, the extent is defined by the index of the first point and the index of the last point. The extent should be set before the "Scalars" are set or allocated. The Extent is stored in the order (X, Y, Z). The dataset extent does not have to start at (0,0,0). (0,0,0) is just the extent of the origin. The first point (the one with Id=0) is at extent (Extent[0],Extent[2],Extent[4]). As for any dataset, a data array on point data starts at Id=0.

◆ GetIncrements() [1/6]

virtual vtkIdType* vtkImageData::GetIncrements ( )
virtual

Different ways to get the increments for moving around the data.

GetIncrements() calls ComputeIncrements() to ensure the increments are up to date. The first three methods compute the increments based on the active scalar field while the next three, the scalar field is passed in.

◆ GetContinuousIncrements() [1/2]

virtual void vtkImageData::GetContinuousIncrements ( int  extent[6],
vtkIdType incX,
vtkIdType incY,
vtkIdType incZ 
)
virtual

Different ways to get the increments for moving around the data.

incX is always returned with 0. incY is returned with the increment needed to move from the end of one X scanline of data to the start of the next line. incZ is filled in with the increment needed to move from the end of one image to the start of the next. The proper way to use these values is to for a loop over Z, Y, X, C, incrementing the pointer by 1 after each component. When the end of the component is reached, the pointer is set to the beginning of the next pixel, thus incX is properly set to 0. The first form of GetContinuousIncrements uses the active scalar field while the second form allows the scalar array to be passed in.

◆ GetContinuousIncrements() [2/2]

virtual void vtkImageData::GetContinuousIncrements ( vtkDataArray scalars,
int  extent[6],

virtual void vtkImageData::AllocateScalars ( int  dataType,

virtual

Allocate the point scalars for this dataset.

The data type and the number of components of the array is determined by the meta-data in the pipeline information. This is usually produced by a reader/filter upstream in the pipeline.

◆ Crop()

void vtkImageData::Crop ( const int updateExtent)
overridevirtual

Reallocates and copies to set the Extent to updateExtent.

overridevirtual

Return the actual size of the data in kibibytes (1024 bytes).

This number is valid only after the pipeline has updated. The memory size returned is guaranteed to be greater than or equal to the memory required to represent the data (e.g., extra space in arrays, etc. are not included in the return value). THIS METHOD IS THREAD SAFE.

Copy information from this data object to the pipeline information.

This is used by the vtkTrivialProducer that is created when someone calls SetInputData() to connect the image to a pipeline.

◆ PrepareForNewData()

void vtkImageData::PrepareForNewData ( )
overridevirtual

make the output data ready for new data to be inserted.

For most objects we just call Initialize. But for image data we leave the old data in case the memory can be reused.

Reimplemented from vtkDataObject.

◆ ShallowCopy()

void vtkImageData::ShallowCopy ( vtkDataObject src)
overridevirtual

Shallow and Deep copy.

Reimplemented from vtkDataSet.

◆ DeepCopy()

void vtkImageData::DeepCopy ( vtkDataObject src)
overridevirtual

Reimplemented from vtkDataSet.

◆ GetArrayPointerForExtent()

void* vtkImageData::GetArrayPointerForExtent ( vtkDataArray array,
int  extent[6] 
)

These are convenience methods for getting a pointer from any filed array.

It is a start at expanding image filters to process any array (not just scalars).

◆ GetArrayPointer()

void* vtkImageData::GetArrayPointer ( vtkDataArray array,
int  coordinates[3] 
)

◆ GetArrayIncrements()

void vtkImageData::GetArrayIncrements ( vtkDataArray array,
vtkIdType  increments[3] 
)

Since various arrays have different number of components, the will have different increments.

◆ ComputeInternalExtent()

void vtkImageData::ComputeInternalExtent ( int intExt,
int tgtExt,
int bnds 
)

Given how many pixel are required on a side for bounrary conditions (in bnds), the target extent to traverse, compute the internal extent (the extent for this ImageData that does not suffer from any boundary conditions) and place it in intExt.

◆ GetExtentType()

int vtkImageData::GetExtentType ( )
inlineoverridevirtual

The extent type is a 3D extent.

Reimplemented from vtkDataObject.
