Detailed Description

2D text annotation

vtkTextMapper provides 2D text annotation support for VTK. It is a vtkMapper2D that can be associated with a vtkActor2D and placed into a vtkRenderer.

To use vtkTextMapper, specify an input text string.

Member Function Documentation

virtual const char* vtkTextMapper::GetClassName ( ) [virtual]

Reimplemented from vtkMapper2D.

Reimplemented in vtkOpenGLFreeTypeTextMapper, and vtkMesaFreeTypeTextMapper.

static int vtkTextMapper::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 vtkMapper2D.

Reimplemented in vtkOpenGLFreeTypeTextMapper, and vtkMesaFreeTypeTextMapper.

virtual int vtkTextMapper::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 vtkMapper2D.

Reimplemented in vtkOpenGLFreeTypeTextMapper, and vtkMesaFreeTypeTextMapper.

static vtkTextMapper* vtkTextMapper::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkMapper2D.

Reimplemented in vtkOpenGLFreeTypeTextMapper, and vtkMesaFreeTypeTextMapper.

void vtkTextMapper::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 vtkMapper2D.

Reimplemented in vtkOpenGLFreeTypeTextMapper, and vtkMesaFreeTypeTextMapper.

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

Creates a new text mapper.

Reimplemented from vtkAlgorithm.

Reimplemented in vtkOpenGLFreeTypeTextMapper, and vtkMesaFreeTypeTextMapper.

virtual void vtkTextMapper::GetSize	(	vtkViewport *	,
		int	size[2]
	)		`[inline, virtual]`

Return the size[2]/width/height of the rectangle required to draw this mapper (in pixels).

Reimplemented in vtkOpenGLFreeTypeTextMapper, and vtkMesaFreeTypeTextMapper.

Definition at line 55 of file vtkTextMapper.h.

virtual int vtkTextMapper::GetWidth ( vtkViewport * v ) [virtual]

Return the size[2]/width/height of the rectangle required to draw this mapper (in pixels).

virtual int vtkTextMapper::GetHeight ( vtkViewport * v ) [virtual]

Return the size[2]/width/height of the rectangle required to draw this mapper (in pixels).

virtual void vtkTextMapper::SetInput ( const char * inputString ) [virtual]

Set the input text string to the mapper. The mapper recognizes "\n" as a carriage return/linefeed (line separator).

virtual char* vtkTextMapper::GetInput ( ) [virtual]

Set the input text string to the mapper. The mapper recognizes "\n" as a carriage return/linefeed (line separator).

virtual void vtkTextMapper::SetTextProperty ( vtkTextProperty * p ) [virtual]

Set/Get the text property.

virtual vtkTextProperty* vtkTextMapper::GetTextProperty ( ) [virtual]

Set/Get the text property.

void vtkTextMapper::ShallowCopy ( vtkTextMapper * tm )

Shallow copy of an actor.

int vtkTextMapper::GetNumberOfLines ( const char * input )

Determine the number of lines in the input string (delimited by "\n").

virtual int vtkTextMapper::GetNumberOfLines ( ) [virtual]

Get the number of lines in the input string (the method GetNumberOfLines(char*) must have been previously called for the return value to be valid).

virtual int vtkTextMapper::SetConstrainedFontSize	(	vtkViewport *	,
		int	targetWidth,
		int	targetHeight
	)		`[virtual]`

Set and return the font size required to make this mapper fit in a given target rectangle (width x height, in pixels). A static version of the method is also available for convenience to other classes (e.g., widgets).

static int vtkTextMapper::SetConstrainedFontSize	(	vtkTextMapper *	,
		vtkViewport *	,
		int	targetWidth,
		int	targetHeight
	)		`[static]`

Set and return the font size required to make this mapper fit in a given target rectangle (width x height, in pixels). A static version of the method is also available for convenience to other classes (e.g., widgets).

static int vtkTextMapper::SetMultipleConstrainedFontSize	(	vtkViewport *	,
		int	targetWidth,
		int	targetHeight,
		vtkTextMapper **	mappers,
		int	nbOfMappers,
		int *	maxResultingSize
	)		`[static]`

Set and return the font size required to make each element of an array of mappers fit in a given rectangle (width x height, in pixels). This font size is the smallest size that was required to fit the largest mapper in this constraint.

static int vtkTextMapper::SetRelativeFontSize	(	vtkTextMapper *	,
		vtkViewport *	,
		int *	winSize,
		int *	stringSize,
		float	sizeFactor = `0.0`
	)		`[static]`

Use these methods when setting font size relative to the renderer's size. These methods are static so that external classes (e.g., widgets) can easily use them.

static int vtkTextMapper::SetMultipleRelativeFontSize	(	vtkViewport *	viewport,
		vtkTextMapper **	textMappers,
		int	nbOfMappers,
		int *	winSize,
		int *	stringSize,
		float	sizeFactor
	)		`[static]`

Use these methods when setting font size relative to the renderer's size. These methods are static so that external classes (e.g., widgets) can easily use them.

virtual int vtkTextMapper::GetSystemFontSize ( int size ) [inline, virtual]

Get the available system font size matching a font size.
