Thanks:
Thanks to C. Charles Law who developed this class.
vtkImageCanvasSource2D is a source that starts as a blank image. you may add to the image with two-dimensional drawing routines. It can paint multi-spectral images.

Member Function Documentation

vtkImageCanvasSource2D* vtkImageCanvasSource2D::New (    )  [static]
 

Construct an instance of vtkImageCanvasSource2D with no data.

Reimplemented from vtkStructuredPoints.

virtual const char* vtkImageCanvasSource2D::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 vtkStructuredPoints.

int vtkImageCanvasSource2D::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 vtkStructuredPoints.

virtual int vtkImageCanvasSource2D::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 vtkStructuredPoints.

vtkImageCanvasSource2D* vtkImageCanvasSource2D::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 vtkStructuredPoints.

void vtkImageCanvasSource2D::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 vtkImageData.

void vtkImageCanvasSource2D::SetImageData (  vtkImageData *    image ) 
 

To drawing into a different image, set it with this method.

virtual vtkImageData* vtkImageCanvasSource2D::GetImageData (    )  [virtual]

vtkImageData* vtkImageCanvasSource2D::GetOutput (    )  [inline]
 

To make Canvas source more like other sources, this get output method should be used.

Definition at line 121 of file vtkImageCanvasSource2D.h.
