Detailed Description

map the input image through a lookup table.

Date:

2000/12/10 20:09:08

Revision:

1.10

Thanks:

Thanks to David G. Gobbi who developed this class.

The vtkImageMapToColors filter will take an input image of any valid scalar type, and map the first component of the image through a lookup table. The result is an image of type VTK_UNSIGNED_CHAR. If the lookup table is not set, or is set to NULL, then the input data will be passed through if it is already of type UNSIGNED_CHAR.

Member Function Documentation

vtkImageMapToColors* vtkImageMapToColors::New (    )  [static]

Instantiate object with no start, end, or progress methods. Reimplemented from vtkImageToImageFilter. Reimplemented in vtkImageMapToRGBA, and vtkImageMapToWindowLevelColors.

virtual const char* vtkImageMapToColors::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 vtkImageToImageFilter. Reimplemented in vtkImageMapToRGBA, and vtkImageMapToWindowLevelColors.

int vtkImageMapToColors::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 vtkImageToImageFilter. Reimplemented in vtkImageMapToRGBA, and vtkImageMapToWindowLevelColors.

virtual int vtkImageMapToColors::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 vtkImageToImageFilter. Reimplemented in vtkImageMapToRGBA, and vtkImageMapToWindowLevelColors.

vtkImageMapToColors* vtkImageMapToColors::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 vtkImageToImageFilter. Reimplemented in vtkImageMapToRGBA, and vtkImageMapToWindowLevelColors.

void vtkImageMapToColors::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 vtkImageToImageFilter. Reimplemented in vtkImageMapToWindowLevelColors.

virtual void vtkImageMapToColors::SetLookupTable (  vtkScalarsToColors *    )  [virtual]

Set the lookup table.

virtual vtkScalarsToColors* vtkImageMapToColors::GetLookupTable (    )  [virtual]

virtual void vtkImageMapToColors::SetOutputFormat (  int    )  [virtual]

Set the output format, the default is RGBA.

virtual int vtkImageMapToColors::GetOutputFormat (    )  [virtual]

void vtkImageMapToColors::SetOutputFormatToRGBA (    )  [inline]

Definition at line 80 of file vtkImageMapToColors.h.

void vtkImageMapToColors::SetOutputFormatToRGB (    )  [inline]

Definition at line 81 of file vtkImageMapToColors.h.

void vtkImageMapToColors::SetOutputFormatToLuminanceAlpha (    )  [inline]

void vtkImageMapToColors::SetOutputFormatToLuminance (    )  [inline]

Definition at line 83 of file vtkImageMapToColors.h.

unsigned long vtkImageMapToColors::GetMTime (    )  [virtual]

We need to check the modified time of the lookup table too. Reimplemented from vtkObject.

void vtkImageMapToColors::UpdateData (  vtkDataObject *    output )  [virtual]

Reimplemented from vtkSource. Reimplemented in vtkImageMapToWindowLevelColors.

void vtkImageMapToColors::operator= (  const vtkImageMapToColors &    )  [inline, protected]

Definition at line 93 of file vtkImageMapToColors.h.

void vtkImageMapToColors::ExecuteInformation (  vtkImageData *    inData, vtkImageData *    outData )  [protected, virtual]

Reimplemented from vtkImageToImageFilter. Reimplemented in vtkImageMapToWindowLevelColors.

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

Reimplemented from vtkImageToImageFilter. Reimplemented in vtkImageMapToWindowLevelColors. Definition at line 99 of file vtkImageMapToColors.h. Referenced by vtkImageMapToWindowLevelColors::ExecuteInformation().

void vtkImageMapToColors::ThreadedExecute (  vtkImageData *    inData, vtkImageData *    outData, int    extent[6], int    id )  [protected, virtual]

If the subclass does not define an Execute method, then the task will be broken up, multiple threads will be spawned, and each thread will call this method. It is public so that the thread functions can call this method. Reimplemented from vtkImageToImageFilter. Reimplemented in vtkImageMapToWindowLevelColors.
