Detailed Description

2D Text annotation support

vtkOpenGLFreeTypeTextMapper provides 2D text annotation support for VTK using the FreeType and FTGL libraries. Normally the user should use vtktextMapper which in turn will use this class.

Member Function Documentation

static int vtkOpenGLFreeTypeTextMapper::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 vtkTextMapper.

virtual int vtkOpenGLFreeTypeTextMapper::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 vtkTextMapper.

static vtkOpenGLFreeTypeTextMapper* vtkOpenGLFreeTypeTextMapper::SafeDownCast

(

vtkObjectBase *

o

)

[static]

Reimplemented from vtkTextMapper.

virtual vtkObjectBase* vtkOpenGLFreeTypeTextMapper::NewInstanceInternal

(

)

const [protected, virtual]

Reimplemented from vtkTextMapper.

vtkOpenGLFreeTypeTextMapper* vtkOpenGLFreeTypeTextMapper::NewInstance

(

)

const

Reimplemented from vtkTextMapper.

static vtkOpenGLFreeTypeTextMapper* vtkOpenGLFreeTypeTextMapper::New

(

)

[static]

Creates a new text mapper.

Reimplemented from vtkTextMapper.

virtual void vtkOpenGLFreeTypeTextMapper::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 vtkTextMapper.

void vtkOpenGLFreeTypeTextMapper::SetInput

(

const char *

)

[virtual]

The input text string to the mapper.

Reimplemented from vtkTextMapper.

void vtkOpenGLFreeTypeTextMapper::RenderOverlay	(	vtkViewport *	viewport,
		vtkActor2D *	actor
	)		[virtual]

Actally draw the text.

Reimplemented from vtkTextMapper.

virtual void vtkOpenGLFreeTypeTextMapper::ReleaseGraphicsResources

(

vtkWindow *

)

[virtual]

Release any graphics resources that are being consumed by this actor. The parameter window could be used to determine which graphic resources to release.

Reimplemented from vtkTextMapper.

virtual void vtkOpenGLFreeTypeTextMapper::GetSize	(	vtkViewport *	viewport,
		int	size[2]
	)		[virtual]

Return the the size of the rectangle required to draw this mapper.

Reimplemented from vtkTextMapper.

char* vtkOpenGLFreeTypeTextMapper::NextLine	(	const char *	input,
		int	lineNum
	)		[protected]

These functions are used to parse, process, and render multiple lines

void vtkOpenGLFreeTypeTextMapper::GetMultiLineSize	(	vtkViewport *	viewport,
		int	size[2]
	)		[protected]

These functions are used to parse, process, and render multiple lines

void vtkOpenGLFreeTypeTextMapper::RenderOverlayMultipleLines	(	vtkViewport *	viewport,
		vtkActor2D *	actor
	)		[protected]

These functions are used to parse, process, and render multiple lines
