virtual const char* vtkStringToImage::GetClassName ( )

virtual

Reimplemented from vtkObject.

Reimplemented in vtkQtStringToImage, and vtkFreeTypeStringToImage.

static int vtkStringToImage::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 vtkObject.

Reimplemented in vtkQtStringToImage, and vtkFreeTypeStringToImage.

virtual int vtkStringToImage::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 vtkQtStringToImage, and vtkFreeTypeStringToImage.

static vtkStringToImage* vtkStringToImage::SafeDownCast ( vtkObject * o )

static

Reimplemented from vtkObject.

Reimplemented in vtkQtStringToImage, and vtkFreeTypeStringToImage.

virtual void vtkStringToImage::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 vtkQtStringToImage, and vtkFreeTypeStringToImage.

virtual vtkVector2i vtkStringToImage::GetBounds	(	vtkTextProperty *	property,
		const vtkUnicodeString &	string
	)

pure virtual

Given a text property and a string, get the bounding box [xmin, xmax] x [ymin, ymax]. Note that this is the bounding box of the area where actual pixels will be written, given a text/pen/baseline location of (0,0). For example, if the string starts with a 'space', or depending on the orientation, you can end up with a [-20, -10] x [5, 10] bbox (the math to get the real bbox is straightforward). Return 1 on success, 0 otherwise. You can use IsBoundingBoxValid() to test if the computed bbox is valid (it may not if GetBoundingBox() failed or if the string was empty).

Implemented in vtkQtStringToImage, and vtkFreeTypeStringToImage.

pure virtual

Given a text property and a string, this function initializes the vtkImageData *data and renders it in a vtkImageData.

Implemented in vtkQtStringToImage, and vtkFreeTypeStringToImage.

virtual int vtkStringToImage::RenderString	(	vtkTextProperty *	property,
		const vtkStdString &	string,
		vtkImageData *	data
	)

pure virtual

Implemented in vtkQtStringToImage, and vtkFreeTypeStringToImage.

virtual void vtkStringToImage::SetScaleToPowerOfTwo ( bool scale )

virtual

Should we produce images at powers of 2, makes rendering on old OpenGL hardware easier. Default is false.

Reimplemented in vtkFreeTypeStringToImage.

virtual bool vtkStringToImage::GetScaleToPowerOfTwo ( )

virtual

Should we produce images at powers of 2, makes rendering on old OpenGL hardware easier. Default is false.
