Detailed Description

all children of this item are transformed by the vtkTransform2D of this item.

This class can be used to transform all child items of this class. The default transform is the identity.

Member Function Documentation

virtual const char* vtkContextTransform::GetClassName ( )

virtual

Reimplemented from vtkAbstractContextItem.

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

static

virtual int vtkContextTransform::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 vtkAbstractContextItem.

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

static

virtual void vtkContextTransform::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 vtkAbstractContextItem.

static vtkContextTransform* vtkContextTransform::New ( )

static

Creates a vtkContextTransform object.

virtual void vtkContextTransform::Update ( )

virtual

Perform any updates to the item that may be necessary before rendering. The scene should take care of calling this on all items before their Paint function is invoked.

Reimplemented from vtkAbstractContextItem.

virtual bool vtkContextTransform::Paint ( vtkContext2D *  painter )

virtual

Paint event for the item, called whenever the item needs to be drawn.

Reimplemented from vtkAbstractContextItem.

virtual void vtkContextTransform::Translate ( float  dx, float  dy  )

virtual

Translate the item by the specified amounts dx and dy in the x and y directions.

virtual void vtkContextTransform::Scale ( float  dx, float  dy  )

virtual

Scale the item by the specified amounts dx and dy in the x and y directions.

virtual void vtkContextTransform::Rotate ( float  angle )

virtual

Rotate the item by the specified angle.

virtual vtkTransform2D* vtkContextTransform::GetTransform ( )

virtual

Access the vtkTransform2D that controls object transformation.

virtual vtkVector2f vtkContextTransform::MapToParent ( const vtkVector2f &  point )

virtual

Transforms a point to the parent coordinate system.

Reimplemented from vtkAbstractContextItem.

virtual vtkVector2f vtkContextTransform::MapFromParent ( const vtkVector2f &  point )

virtual

Transforms a point from the parent coordinate system.

Reimplemented from vtkAbstractContextItem.
