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 vtkMesaFreeTypeTextMapper, and vtkOpenGLFreeTypeTextMapper.

static int vtkTextMapper::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkMapper2D.

Reimplemented in vtkMesaFreeTypeTextMapper, and vtkOpenGLFreeTypeTextMapper.

virtual int vtkTextMapper::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkMapper2D.

Reimplemented in vtkMesaFreeTypeTextMapper, and vtkOpenGLFreeTypeTextMapper.

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

Reimplemented from vtkMapper2D.

Reimplemented in vtkMesaFreeTypeTextMapper, and vtkOpenGLFreeTypeTextMapper.

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 vtkMesaFreeTypeTextMapper, and vtkOpenGLFreeTypeTextMapper.

static vtkTextMapper* vtkTextMapper::New  )  [static]
 

Creates a new text mapper.

Reimplemented from vtkAlgorithm.

Reimplemented in vtkMesaFreeTypeTextMapper, and vtkOpenGLFreeTypeTextMapper.

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 vtkMesaFreeTypeTextMapper, and vtkOpenGLFreeTypeTextMapper.

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.

virtual int vtkTextMapper::GetNumberOfLines  )  [virtual]
 

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::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 * height, in pixels).

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 * height, in pixels). This font size is the smallest size that was required to fit the largest mapper in this constraint. The resulting maximum area of the mappers is also returned.

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

Get the available system font size matching a font size.
