Public Member Functions

 FourColTranspFillAttribute ()
 Default Constuctor for fill attribute values.
virtual INT32 operator== (const FillGeometryAttribute &Attrib)
 A virtual comparison operator. See NodeAttribute::operator== for a description of why it's required.
virtual NodeAttribute * MakeNode ()
 Make a AttrFourColTranspFill node from this graduated fill attribute.
virtual UINT32 * GetEndTransp3 ()
virtual void SetEndTransp3 (UINT32 *NewTransp)
 Sets the third transparency of this fill.
virtual BOOL IsAFourColFill ()
virtual ColourFillAttribute * MakeSimilarNonTranspFillGeometry (double TransparencyScale)
 Creates a non-transparent version of this transparent fill attribute. (The original use of this was so airbrushes could maintain their fill's transparency geometry).

INT32 FourColTranspFillAttribute::operator== (  const FillGeometryAttribute &  Attrib  )  [virtual]
 

A virtual comparison operator. See NodeAttribute::operator== for a description of why it's required.

Author:
Gerry_Iles (Xara Group Ltd) <camelotdev@xara.com>
Date:
15/8/96
Parameters:
Attrib - the attribute to compare, which must be an AttrFillGeometry [INPUTS]
Returns:
Usual semantics for equality.

Errors: An ENSURE failure will occur if Attrib does not have a AttrFlatGeometry runtime class.
