virtual const char* vtkQtStringToImage::GetClassName (  )  [virtual]

Reimplemented from vtkStringToImage.

static int vtkQtStringToImage::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 vtkStringToImage.

virtual int vtkQtStringToImage::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 vtkStringToImage.

static vtkQtStringToImage* vtkQtStringToImage::SafeDownCast ( vtkObject o  )  [static]

Reimplemented from vtkStringToImage.

virtual void vtkQtStringToImage::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 vtkStringToImage.

static vtkQtStringToImage* vtkQtStringToImage::New (  )  [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

virtual vtkVector2i vtkQtStringToImage::GetBounds ( vtkTextProperty property,
const vtkUnicodeString string 
) [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).

Implements vtkStringToImage.

const vtkStdString string

virtual int vtkQtStringToImage::RenderString ( vtkTextProperty property,
const vtkUnicodeString string,
vtkImageData data 
) [virtual]

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

Implements vtkStringToImage.

virtual int vtkQtStringToImage::RenderString ( vtkTextProperty property,
const vtkStdString string,
vtkImageData data 
) [virtual]

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

Implements vtkStringToImage.

void vtkQtStringToImage::DeepCopy ( vtkQtStringToImage utility  ) 

Make a deep copy of the supplied utility class.
