Detailed Description

create polygonal text

vtkTextSource converts a text string into polygons. This way you can insert text into your renderings. It uses the 9x15 font from X Windows. You can specify if you want the background to be drawn or not. The characters are formed by scan converting the raster font into quadrilaterals. Colors are assigned to the letters using scalar data. To set the color of the characters with the source's actor property, set BackingOff on the text source and ScalarVisibilityOff on the associated vtkPolyDataMapper. Then, the color can be set using the associated actor's property.

vtkVectorText generates higher quality polygonal representations of characters.

Member Function Documentation

static int vtkTextSource::IsTypeOf ( const char * name ) [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 vtkPolyDataAlgorithm.

virtual int vtkTextSource::IsA ( const char * name ) [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 vtkPolyDataAlgorithm.

static vtkTextSource* vtkTextSource::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkPolyDataAlgorithm.

virtual vtkObjectBase* vtkTextSource::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkPolyDataAlgorithm.

vtkTextSource* vtkTextSource::NewInstance ( ) const

Reimplemented from vtkPolyDataAlgorithm.

void vtkTextSource::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 vtkPolyDataAlgorithm.

static vtkTextSource* vtkTextSource::New ( ) [static]

Construct object with no string set and backing enabled.

Reimplemented from vtkPolyDataAlgorithm.

virtual void vtkTextSource::SetText ( const char * ) [virtual]

Set/Get the text to be drawn.

virtual char* vtkTextSource::GetText ( ) [virtual]

Set/Get the text to be drawn.

virtual void vtkTextSource::SetBacking ( int ) [virtual]

Controls whether or not a background is drawn with the text.

virtual int vtkTextSource::GetBacking ( ) [virtual]

Controls whether or not a background is drawn with the text.

virtual void vtkTextSource::BackingOn ( ) [virtual]

Controls whether or not a background is drawn with the text.

virtual void vtkTextSource::BackingOff ( ) [virtual]

Controls whether or not a background is drawn with the text.

virtual void vtkTextSource::SetForegroundColor	(	double	,
		double	,
		double
	)		`[virtual]`

Set/Get the foreground color. Default is white (1,1,1). ALpha is always 1.

virtual void vtkTextSource::SetForegroundColor ( double [3] ) [virtual]

Set/Get the foreground color. Default is white (1,1,1). ALpha is always 1.

virtual double* vtkTextSource::GetForegroundColor ( ) [virtual]

Set/Get the foreground color. Default is white (1,1,1). ALpha is always 1.

virtual void vtkTextSource::GetForegroundColor ( double data[3] ) [virtual]

Set/Get the foreground color. Default is white (1,1,1). ALpha is always 1.

virtual void vtkTextSource::SetBackgroundColor	(	double	,
		double	,
		double
	)		`[virtual]`

Set/Get the background color. Default is black (0,0,0). Alpha is always 1.

virtual void vtkTextSource::SetBackgroundColor ( double [3] ) [virtual]

Set/Get the background color. Default is black (0,0,0). Alpha is always 1.

virtual double* vtkTextSource::GetBackgroundColor ( ) [virtual]

Set/Get the background color. Default is black (0,0,0). Alpha is always 1.

virtual void vtkTextSource::GetBackgroundColor ( double data[3] ) [virtual]

Set/Get the background color. Default is black (0,0,0). Alpha is always 1.
