◆ IsTypeOf()

static vtkTypeBool vtkLabeledContourPolyDataItem::IsTypeOf ( const char *  type)
static

◆ IsA()

virtual vtkTypeBool vtkLabeledContourPolyDataItem::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 vtkPolyDataItem.

◆ SafeDownCast()

◆ NewInstance()

◆ PrintSelf()

void vtkLabeledContourPolyDataItem::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
overridevirtual

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 vtkContextItem.

◆ New()

static vtkLabeledContourPolyDataItem * vtkLabeledContourPolyDataItem::New ( )
static

◆ Paint()

bool vtkLabeledContourPolyDataItem::Paint ( vtkContext2D painter)
overridevirtual

Paint event for the item.

Reimplemented from vtkAbstractContextItem.

◆ SetTextProperty()

virtual void vtkLabeledContourPolyDataItem::SetTextProperty ( vtkTextProperty tprop)
virtual

The text property used to label the lines.

Note that both vertical and horizontal justifications will be reset to "Centered" prior to rendering.

Note
This is a convenience method that clears TextProperties and inserts the argument as the only property in the collection.
See also
SetTextProperties

◆ SetTextProperties()

virtual void vtkLabeledContourPolyDataItem::SetTextProperties ( vtkTextPropertyCollection coll)
virtual

The text properties used to label the lines.

Note that both vertical and horizontal justifications will be reset to "Centered" prior to rendering.

If the TextPropertyMapping array exists, then it is used to identify which text property to use for each label as follows: If the scalar value of a line is found in the mapping, the index of the value in mapping is used to lookup the text property in the collection. If there are more mapping values than properties, the properties are looped through until the mapping is exhausted.

Lines with scalar values missing from the mapping are assigned text properties in a round-robin fashion starting from the beginning of the collection, repeating from the start of the collection as necessary.

SetTextPropertyMapping

◆ GetTextProperties()

virtual vtkTextPropertyCollection * vtkLabeledContourPolyDataItem::GetTextProperties ( )
virtual

The text properties used to label the lines.

Note that both vertical and horizontal justifications will be reset to "Centered" prior to rendering.

If the TextPropertyMapping array exists, then it is used to identify which text property to use for each label as follows: If the scalar value of a line is found in the mapping, the index of the value in mapping is used to lookup the text property in the collection. If there are more mapping values than properties, the properties are looped through until the mapping is exhausted.

Lines with scalar values missing from the mapping are assigned text properties in a round-robin fashion starting from the beginning of the collection, repeating from the start of the collection as necessary.

◆ GetTextPropertyMapping()

virtual vtkDoubleArray * vtkLabeledContourPolyDataItem::GetTextPropertyMapping ( )
virtual

Values in this array correspond to vtkTextProperty objects in the TextProperties collection.

If a contour line's scalar value exists in this array, the corresponding text property is used for the label. See SetTextProperties for more information.

◆ SetTextPropertyMapping()

virtual void vtkLabeledContourPolyDataItem::SetTextPropertyMapping ( vtkDoubleArray mapping)
virtual

Values in this array correspond to vtkTextProperty objects in the TextProperties collection.

If a contour line's scalar value exists in this array, the corresponding text property is used for the label. See SetTextProperties for more information.

◆ SetLabelVisibility()

virtual void vtkLabeledContourPolyDataItem::SetLabelVisibility ( bool  )
virtual

If true, labels will be placed and drawn during rendering.

Otherwise, only the mapper returned by GetPolyDataMapper() will be rendered. The default is to draw labels.

◆ GetLabelVisibility()

virtual bool vtkLabeledContourPolyDataItem::GetLabelVisibility ( )
virtual

If true, labels will be placed and drawn during rendering.

Otherwise, only the mapper returned by GetPolyDataMapper() will be rendered. The default is to draw labels.

◆ LabelVisibilityOn()

virtual void vtkLabeledContourPolyDataItem::LabelVisibilityOn ( )

If true, labels will be placed and drawn during rendering.

Otherwise, only the mapper returned by GetPolyDataMapper() will be rendered. The default is to draw labels.

◆ LabelVisibilityOff()

virtual void vtkLabeledContourPolyDataItem::LabelVisibilityOff ( )
virtual

If true, labels will be placed and drawn during rendering.

Otherwise, only the mapper returned by GetPolyDataMapper() will be rendered. The default is to draw labels.

◆ SetSkipDistance()

virtual void vtkLabeledContourPolyDataItem::SetSkipDistance ( double  )
virtual

Ensure that there are at least SkipDistance pixels between labels.

This is only enforced on labels along the same line. The default is 0.

◆ GetSkipDistance()
