Public Member Functions

 FillMappingAttribute ()
 Constructor for mapping attributes.
virtual void Restore (RenderRegion *, BOOL)
 Restores the fill type attribute for the given render region. i.e. all paths filled will now be filled with this fill attribute.
virtual void Render (RenderRegion *, BOOL Temp=FALSE)
 Sets the fill type attribute for the given render region. i.e. all paths filled will now be filled with this fill attribute.
virtual void SimpleCopy (AttributeValue *)
 See AttributeValue::SimpleCopy.
virtual BOOL IsDifferent (AttributeValue *)
 Compare two AttributeValue objects. The base class version always returns TRUE - derived classes should override this function to provide functionality.
virtual FillMappingAttribute & operator= (FillMappingAttribute &Attrib)
virtual INT32 operator== (const FillMappingAttribute &Attrib)

Static Public Member Functions

static BOOL Init ()
 Registers fill mapping attribute, and provides a default attribute to give linear graduations.

Member Function Documentation

BOOL FillMappingAttribute::Init (  void   )  [static]
 

Registers fill mapping attribute, and provides a default attribute to give linear graduations.

Returns:
TRUE - initialised ok; FALSE if not.

Errors: Out of memory.

BOOL FillMappingAttribute::IsDifferent (  AttributeValue *  pVal  )  [virtual]
 

Compare two AttributeValue objects. The base class version always returns TRUE - derived classes should override this function to provide functionality.

Author:
Tim_Browse (Xara Group Ltd) <camelotdev@xara.com>
Date:
12/04/94
Parameters:
pAttr - the attribute to compare against this one. [INPUTS]
Returns:
TRUE if objects represent different attributes (e.g. one is red and the other is blue); FALSE otherwise (i.e. they represent the same attribute, e.g. both represent 0.25pt lines).
