topologically and geometrically regular array of data
vtkImageData is a data object that is a concrete implementation of vtkDataSet. vtkImageData represents a geometric structure that is a topological and geometrical regular array of points. Examples include volumes (voxel data) and pixmaps. This representation supports images up to three dimensions. The image may also be oriented (see the DirectionMatrices and related transformation methods). Note however, that not all filters support oriented images.

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.

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

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.

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] | ||

vtkIdType vtkImageData::GetTupleIndex | ( | vtkDataArray * | array, |
int | coordinates[3] | ||
) |
Given a data array and a coordinate, return the index of the tuple in the array corresponding to that coordinate.
This method is analogous to GetArrayPointer(), but it conforms to the API of vtkGenericDataArray.
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.
