Detailed Description

Abstract interface to equation rendering.

vtkMathTextUtilities defines an interface for equation rendering. Intended for use with the python matplotlib.mathtext module (implemented in the vtkMatplotlib module).

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

static

virtual int vtkMathTextUtilities::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 vtkObject.

Reimplemented in vtkMatplotlibMathTextUtilities.

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

static

virtual vtkObjectBase* vtkMathTextUtilities::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtkObject.

Reimplemented in vtkMatplotlibMathTextUtilities.

vtkMathTextUtilities* vtkMathTextUtilities::NewInstance ( ) const

void vtkMathTextUtilities::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.

Reimplemented in vtkMatplotlibMathTextUtilities.

virtual bool vtkMathTextUtilities::IsAvailable ( )

inlinevirtual

Returns true if mathtext rendering is available.

Reimplemented in vtkMatplotlibMathTextUtilities.

Definition at line 60 of file vtkMathTextUtilities.h.

static vtkMathTextUtilities* vtkMathTextUtilities::New ( )

static

This is a singleton pattern New. There will be only ONE reference to a vtkMathTextUtilities object per process. Clients that call this method must use Delete() on the object so that reference counting will work. The single instance will be unreferenced when the program exits. You should just use the static GetInstance() method anyway to get the singleton.

static vtkMathTextUtilities* vtkMathTextUtilities::GetInstance ( )

static

Return the singleton instance with no reference counting.

static void vtkMathTextUtilities::SetInstance ( vtkMathTextUtilities * instance )

static

Supply a user defined instance. Call Delete() on the supplied instance after setting it to fix the reference count.

virtual bool vtkMathTextUtilities::GetBoundingBox	(	vtkTextProperty *	tprop,
		const char *	str,
		int	dpi,
		int	bbox[4]
	)

pure virtual

Determine the dimensions of the image that RenderString will produce for a given str, tprop, and dpi

Implemented in vtkMatplotlibMathTextUtilities.

virtual bool vtkMathTextUtilities::GetMetrics	(	vtkTextProperty *	tprop,
		const char *	str,
		int	dpi,
		vtkTextRenderer::Metrics &	metrics
	)

pure virtual

Return the metrics for the rendered str, tprop, and dpi.

Implemented in vtkMatplotlibMathTextUtilities.

virtual bool vtkMathTextUtilities::RenderString	(	const char *	str,
		vtkImageData *	data,
		vtkTextProperty *	tprop,
		int	dpi,
		int	textDims[2] = `NULL`
	)

pure virtual

Render the given string str into the vtkImageData data with a resolution of dpi. textDims, will be overwritten by the pixel width and height of the rendered string. This is useful when ScaleToPowerOfTwo is set to true, and the image dimensions may not match the dimensions of the rendered text.

Implemented in vtkMatplotlibMathTextUtilities.

virtual bool vtkMathTextUtilities::StringToPath	(	const char *	str,
		vtkPath *	path,
		vtkTextProperty *	tprop,
		int	dpi
	)

pure virtual

Parse the MathText expression in str and fill path with a contour of the glyphs.

Implemented in vtkMatplotlibMathTextUtilities.

virtual int vtkMathTextUtilities::GetConstrainedFontSize	(	const char *	str,
		vtkTextProperty *	tprop,
		int	targetWidth,
		int	targetHeight,
		int	dpi
	)

virtual

This function returns the font size (in points) required to fit the string in the target rectangle. The font size of tprop is updated to the computed value as well. If an error occurs (e.g. an improperly formatted MathText string), -1 is returned.

virtual bool vtkMathTextUtilities::GetScaleToPowerOfTwo ( )

pure virtual

Set to true if the graphics implmentation requires texture image dimensions to be a power of two. Default is true, but this member will be set appropriately when GL is inited.

Implemented in vtkMatplotlibMathTextUtilities.

virtual void vtkMathTextUtilities::SetScaleToPowerOfTwo ( bool scale )

pure virtual

Set to true if the graphics implmentation requires texture image dimensions to be a power of two. Default is true, but this member will be set appropriately when GL is inited.

Implemented in vtkMatplotlibMathTextUtilities.
