virtual vtkIdType* vtkImageData::GetIncrements ( ) [virtual]

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

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.

Set/Get the origin of the dataset. The origin is the position in world coordinates of the point of extent (0,0,0). This point does not have to be part of the dataset, in other words, the dataset extent does not have to start at (0,0,0) and the origin can be outside of the dataset bounding box. The origin plus spacing determine the position in space of the points.

virtual void vtkImageData::CopyInformationFromPipeline ( vtkInformation information) [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.

Reimplemented from vtkDataObject.

virtual void vtkImageData::ShallowCopy ( vtkDataObject src) [virtual]

Shallow and Deep copy.

Reimplemented from vtkDataSet.

Reimplemented in vtkUniformGrid.

virtual void vtkImageData::DeepCopy ( vtkDataObject src) [virtual]

Shallow and Deep copy.

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,

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 not suffer from any boundary conditions) and place it in intExt
