Detailed Description

Paints on a canvas.

Revision:
1.26
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. This object is unusual because it is a data object itself and not a source.
Examples:

Tests:

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 draw into a different image, set it with this method.

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

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

virtual void vtkImageCanvasSource2D::SetDrawColor (  float   ,
float   ,
float   ,
float   
)  [virtual]
 

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

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

virtual float* vtkImageCanvasSource2D::GetDrawColor (    )  [virtual]
 

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

void vtkImageCanvasSource2D::FillPixel (  int    x,
int    y
) 
 

Fill a colored area with another color. (like connectivity) All pixels connected (and with the same value) to pixel (x, y) get replaced by the current "DrawColor".

vtkImageData* vtkImageCanvasSource2D::GetOutput (    )  [inline]
 

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

Definition at line 128 of file vtkImageCanvasSource2D.h.

void vtkImageCanvasSource2D::SetExtent (  int *    extent ) 
 

These methods also set the WholeExtent of this "DataObject". This is just like vtkImageData. It sets the size of the canvas. Extent is a min max 3D box. Minimums and maximums are inclusive.

void vtkImageCanvasSource2D::SetExtent (  int    x1,
int    x2,
int    y1,
int    y2,
int    z1,

) 
 

These methods also set the WholeExtent of this "DataObject". This is just like vtkImageData. It sets the size of the canvas. Extent is a min max 3D box. Minimums and maximums are inclusive.

Reimplemented from vtkImageData.

virtual void vtkImageCanvasSource2D::SetDefaultZ (  int    )  [virtual]
 

The drawing operations can only draw into one 2D XY plane at a time. If the canvas is a 3D volume, then this z value is used as the default for 2D operations.

virtual int vtkImageCanvasSource2D::GetDefaultZ (    )  [virtual]
 

The drawing operations can only draw into one 2D XY plane at a time. If the canvas is a 3D volume, then this z value is used as the default for 2D operations.
