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.

virtual unsigned long vtkImageData::GetEstimatedMemorySize (  )  [virtual]

Get the estimated size of this data object itself. Should be called after UpdateInformation() and PropagateUpdateExtent() have both been called. This estimate should be fairly accurate since this is structured data.

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.

virtual void vtkImageData::Crop (  )  [virtual]

Reallocates and copies to set the Extent to the UpdateExtent. This is used internally when the exact extent is requested, and the source generated more than the update extent.

Reimplemented from vtkDataObject.

virtual unsigned long vtkImageData::GetActualMemorySize (  )  [virtual]

Return the actual size of the data in kilobytes. This number is valid only after the pipeline has updated.

Note that these methods are setting and getting the pipeline scalar type. i.e. they are setting the type that the image data will be once it has executed. Until the REQUEST_DATA pass the actual scalars may be of some other type. This is for backwards compatibility

virtual void vtkImageData::CopyTypeSpecificInformation ( vtkDataObject data  )  [virtual]

By default, there is no type specific information

Reimplemented from vtkDataObject.

virtual void vtkImageData::CopyInformationToPipeline ( vtkInformation request,
vtkInformation input,
vtkInformation output,
int  forceCopy 
) [virtual]

Override these to handle origin, spacing, scalar type, and scalar number of components. See vtkDataObject for details.

virtual void vtkImageData::PrepareForNewData (  )  [virtual]

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.

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).

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

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).

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

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

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 nto suffer from any boundary conditions) and place it in intExt

virtual int vtkImageData::GetExtentType (  )  [inline, virtual]

The extent type is a 3D extent
