## Detailed Description

show two images at once using a checkboard pattern

Date:
  2002/05/07 21:11:36

Revision:
  1.7

vtkImageCheckerboard displays two images as one using a checkerboard pattern. This filter can be used to compare two images. The checkerboard pattern is controlled by the NumberOfDivisions ivar. This controls the number of checkerboard divisions in the whole extent of the image.

## Member Function Documentation

vtkImageCheckerboard* vtkImageCheckerboard::New | ( |  | ) | `[static]`

| Create an object with Debug turned off, modified time initialized to zero, and reference counting on. Reimplemented from vtkObject.

virtual const char* vtkImageCheckerboard::GetClassName | ( |  | ) | `[virtual]`

| Reimplemented from vtkImageTwoInputFilter.

int vtkImageCheckerboard::IsTypeOf | ( | const char * | type | ) | `[static]`

| Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkImageTwoInputFilter.

virtual int vtkImageCheckerboard::IsA | ( | const char * | type | ) | `[virtual]`

| Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkImageTwoInputFilter.

vtkImageCheckerboard* vtkImageCheckerboard::SafeDownCast | ( | vtkObject * | o | ) | `[static]`

| Reimplemented from vtkImageTwoInputFilter.

void vtkImageCheckerboard::PrintSelf | ( | ostream & | os,
|  | vtkIndent | indent
| ) | `[virtual]`

| Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkImageTwoInputFilter.

virtual void vtkImageCheckerboard::SetNumberOfDivisions | ( | int | ,
|  | int | ,
|  | int |
| ) | `[virtual]`

| Set/Get the number of divisions along each axis.

virtual void vtkImageCheckerboard::SetNumberOfDivisions | ( | int | [3] | ) | `[virtual]`

| Set/Get the number of divisions along each axis.

virtual int* vtkImageCheckerboard::GetNumberOfDivisions | ( |  | ) | `[virtual]`

| Set/Get the number of divisions along each axis.

virtual void vtkImageCheckerboard::GetNumberOfDivisions | ( | int | data[3] | ) | `[virtual]`

| Set/Get the number of divisions along each axis.

void vtkImageCheckerboard::ThreadedExecute | ( | vtkImageData ** | inDatas,
|  | vtkImageData * | outData,
|  | int | extent[6],
|  | int | id
| ) | `[protected, virtual]`

| The execute method created by the subclass. This is kept public instead of protected since it is called from a non-member thread function. Reimplemented from vtkImageMultipleInputFilter.
