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

void vtkImageCanvasSource2D::FillPixel int    x,
int    y
 

Fill a colored area with another color. (like connectivity) All pixels connected to pixel (x, y) get replaced by draw color.

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.

vtkImageData* vtkImageCanvasSource2D::GetOutput   [inline]
 

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

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.

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.

vtkImageCanvasSource2D* vtkImageCanvasSource2D::New   [static]
 

Construct an instance of vtkImageCanvasSource2D with no data.

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.

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.

virtual void vtkImageCanvasSource2D::SetDefaultZ int    [virtual]
 

If the canvas is a 3D volume, then this z value is used as the default for 2D operations.

void vtkImageCanvasSource2D::SetDrawColor int    dim,
float *    color
 

Set/Get DrawValue. This is the value that is used when filling data or drawing lines.

void vtkImageCanvasSource2D::SetExtent int *    extent
 

These methods also set the WholeExtent of this "DataObject".

void vtkImageCanvasSource2D::SetImageData vtkImageData   image
 

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