Detailed Description

Renders labels with freetype.

Uses the FreeType to render labels and compute label sizes. This strategy may be used with vtkLabelPlacementMapper.

void vtkFreeTypeLabelRenderStrategy::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 vtkObject.

static int vtkFreeTypeLabelRenderStrategy::IsTypeOf ( const char * type )

static

virtual int vtkFreeTypeLabelRenderStrategy::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 vtkLabelRenderStrategy.

static vtkFreeTypeLabelRenderStrategy* vtkFreeTypeLabelRenderStrategy::SafeDownCast ( vtkObjectBase * o )

static

virtual vtkObjectBase* vtkFreeTypeLabelRenderStrategy::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtkLabelRenderStrategy.

static vtkFreeTypeLabelRenderStrategy* vtkFreeTypeLabelRenderStrategy::New ( )

static

virtual bool vtkFreeTypeLabelRenderStrategy::SupportsRotation ( )

inlinevirtual

The free type render strategy currently does not support rotation.

Reimplemented from vtkLabelRenderStrategy.

Definition at line 42 of file vtkFreeTypeLabelRenderStrategy.h.

virtual bool vtkFreeTypeLabelRenderStrategy::SupportsBoundedSize ( )

inlinevirtual

The free type render strategy currently does not support bounded size labels.

Reimplemented from vtkLabelRenderStrategy.

Definition at line 49 of file vtkFreeTypeLabelRenderStrategy.h.

virtual void vtkFreeTypeLabelRenderStrategy::ComputeLabelBounds	(	vtkTextProperty *	tprop,
		vtkStdString	label,
		double	bds[4]
	)

inlinevirtual

Compute the bounds of a label. Must be performed after the renderer is set.

Reimplemented from vtkLabelRenderStrategy.

Definition at line 56 of file vtkFreeTypeLabelRenderStrategy.h.

virtual void vtkFreeTypeLabelRenderStrategy::ComputeLabelBounds	(	vtkTextProperty *	tprop,
		vtkUnicodeString	label,
		double	bds[4]
	)

virtual

Compute the bounds of a label. Must be performed after the renderer is set.

Implements vtkLabelRenderStrategy.

virtual void vtkFreeTypeLabelRenderStrategy::RenderLabel	(	int	x[2],
		vtkTextProperty *	tprop,
		vtkStdString	label
	)

inlinevirtual

Render a label at a location in world coordinates. Must be performed between StartFrame() and EndFrame() calls.

Reimplemented from vtkLabelRenderStrategy.

Definition at line 64 of file vtkFreeTypeLabelRenderStrategy.h.

virtual void vtkFreeTypeLabelRenderStrategy::RenderLabel	(	int	x[2],
		vtkTextProperty *	tprop,
		vtkStdString	label,
		int	width
	)

inlinevirtual

Render a label at a location in world coordinates. Must be performed between StartFrame() and EndFrame() calls.

Reimplemented from vtkLabelRenderStrategy.

Definition at line 66 of file vtkFreeTypeLabelRenderStrategy.h.

virtual void vtkFreeTypeLabelRenderStrategy::RenderLabel	(	int	x[2],
		vtkTextProperty *	tprop,
		vtkUnicodeString	label
	)

virtual

Render a label at a location in world coordinates. Must be performed between StartFrame() and EndFrame() calls.

Implements vtkLabelRenderStrategy.

virtual void vtkFreeTypeLabelRenderStrategy::RenderLabel	(	int	x[2],
		vtkTextProperty *	tprop,
		vtkUnicodeString	label,
		int	width
	)

inlinevirtual

Render a label at a location in world coordinates. Must be performed between StartFrame() and EndFrame() calls.

Definition at line 69 of file vtkFreeTypeLabelRenderStrategy.h.

virtual void vtkFreeTypeLabelRenderStrategy::ReleaseGraphicsResources ( vtkWindow * window )

virtual

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

Reimplemented from vtkLabelRenderStrategy.
