Export VTK images to third-party systems. More...
#include <vtkImageExport.h>
Detailed Description
Export VTK images to third-party systems.
vtkImageExport provides a way of exporting image data at the end of a pipeline to a third-party system or to a simple C array. Applications can use this to get direct access to the image data in memory. A callback interface is provided to allow connection of the VTK pipeline to a third-party pipeline. This interface conforms to the interface of vtkImageImport. In Python it is possible to use this class to write the image data into a python string that has been pre-allocated to be the correct size.

Member Function Documentation
| static vtkImageExport* vtkImageExport::New | ( | ) | [static] |
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkAlgorithm.
| static int vtkImageExport::IsTypeOf | ( | const char * | name | ) | [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 vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkImageAlgorithm.
| virtual int vtkImageExport::IsA | ( | const char * | name | ) | [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 vtkTypeMacro found in vtkSetGet.h.

| void vtkImageExport::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 vtkImageAlgorithm.
Get the number of bytes required for the output C array.
| void vtkImageExport::GetDataDimensions | ( | int * | ptr | ) |
Get the (x,y,z) index dimensions of the data. Please note that C arrays are indexed in decreasing order, i.e. array[z][y][x].
| int* vtkImageExport::GetDataDimensions | ( | ) | [inline] |
Get the (x,y,z) index dimensions of the data. Please note that C arrays are indexed in decreasing order, i.e. array[z][y][x].
Definition at line 54 of file vtkImageExport.h.
Get the number of scalar components of the data. Please note that when you index into a C array, the scalar component index comes last, i.e. array[z][y][x][c].
Get the scalar type of the data. The scalar type of the C array must match the scalar type of the data.
| const char* vtkImageExport::GetDataScalarTypeAsString | ( | ) | [inline] |

| virtual int vtkImageExport::RequestData | ( | vtkInformation * | request, |

| ) | [protected, virtual] |
This is called in response to a REQUEST_DATA request from the executive. Subclasses should override either this method or the ExecuteDataWithInformation method in order to generate data for their outputs. For images, the output arrays will already be allocated, so all that is necessary is to fill in the voxel values.
