Detailed Description

Collects data from multiple inputs into one image.

Date:

2001/12/07 14:02:28

Revision:

1.24

Thanks:

Thanks to C. Charles Law who developed this class.

vtkImageAppend takes the components from multiple inputs and merges them into one output. The output images are append along the "AppendAxis". Except for the append axis, all inputs must have the same extent. All inputs must have the same number of scalar components. A future extension might be to pad or clip inputs to have the same extent. The output has the same origin and spacing as the first input. The origin and spacing of all other inputs are ignored. All inputs must have the same scalar type.

Member Function Documentation

vtkImageAppend* vtkImageAppend::New (    )  [static]

Instantiate object with no start, end, or progress methods. Reimplemented from vtkImageMultipleInputFilter.

virtual const char* vtkImageAppend::GetClassName (    )  [virtual]

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageMultipleInputFilter.

int vtkImageAppend::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 vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageMultipleInputFilter.

virtual int vtkImageAppend::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 vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageMultipleInputFilter.

vtkImageAppend* vtkImageAppend::SafeDownCast (  vtkObject *    o )  [static]

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageMultipleInputFilter.

void vtkImageAppend::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 vtkImageMultipleInputFilter.

virtual void vtkImageAppend::SetAppendAxis (  int    )  [virtual]

This axis is expanded to hold the multiple images. The default AppendAxis is the X axis. If you want to create a volue from a series of XY images, then you should set the AppendAxis to 2 (Z axis).

virtual int vtkImageAppend::GetAppendAxis (    )  [virtual]

This axis is expanded to hold the multiple images. The default AppendAxis is the X axis. If you want to create a volue from a series of XY images, then you should set the AppendAxis to 2 (Z axis).

virtual void vtkImageAppend::SetPreserveExtents (  int    )  [virtual]

By default "PreserveExtents" is off and the append axis is used. When "PreseveExtents" is on, the extent of the inputs is used to place the image in the output. The whole extent of the output is the union of the input whole extents. Any portion of the output not covered by the inputs is set to zero. The origin and spacing is taken from the first input.

virtual int vtkImageAppend::GetPreserveExtents (    )  [virtual]

By default "PreserveExtents" is off and the append axis is used. When "PreseveExtents" is on, the extent of the inputs is used to place the image in the output. The whole extent of the output is the union of the input whole extents. Any portion of the output not covered by the inputs is set to zero. The origin and spacing is taken from the first input.

virtual void vtkImageAppend::PreserveExtentsOn (    )  [virtual]

By default "PreserveExtents" is off and the append axis is used. When "PreseveExtents" is on, the extent of the inputs is used to place the image in the output. The whole extent of the output is the union of the input whole extents. Any portion of the output not covered by the inputs is set to zero. The origin and spacing is taken from the first input.

virtual void vtkImageAppend::PreserveExtentsOff (    )  [virtual]

By default "PreserveExtents" is off and the append axis is used. When "PreseveExtents" is on, the extent of the inputs is used to place the image in the output. The whole extent of the output is the union of the input whole extents. Any portion of the output not covered by the inputs is set to zero. The origin and spacing is taken from the first input.

void vtkImageAppend::ExecuteInformation (  vtkImageData **    inputs, vtkImageData *    output )  [protected, virtual]

Reimplemented from vtkImageMultipleInputFilter.

void vtkImageAppend::ComputeInputUpdateExtent (  int    inExt[6], int    outExt[6], int    whichInput )  [protected, virtual]

Reimplemented from vtkImageMultipleInputFilter.

void vtkImageAppend::ExecuteInformation (    )  [inline, protected, virtual]

Reimplemented from vtkImageMultipleInputFilter. Definition at line 104 of file vtkImageAppend.h.

void vtkImageAppend::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.

void vtkImageAppend::InitOutput (  int    outExt[6], vtkImageData *    outData )  [protected]
