unpublished interface XParametricPolyPolygon2D
Usage Restrictions
not published
Description
Interface to a dynamic poly-polygon generator, that generates poly-polygons depending on a given parameter value.

The returned poly-polygon should normally be contained in the [0,1]x[0,1] rectangle. At least that is the dimension expected at other places. e.g. Texture.

Methods' Summary
getOutline Query the polygonal outline at the specified value. The returned outline should be clipped to the [0,1]x[0,1] rectangle.  
getColor Query the color value for the polygonal area at the specified parameter value.  
getPointColor Query the color for a dedicated point in the plane.  
getColorSpace Query the color space employed by this object  
Methods' Details
getOutline
XPolyPolygon2D
getOutline( [in] double  t )
raises( ::com::sun::star::lang::IllegalArgumentException );
Description
Query the polygonal outline at the specified value. The returned outline should be clipped to the [0,1]x[0,1] rectangle.
Parameter t
Parameter value in the range [0,1]. During painting, this range is sweeped through starting from 0. When using such a parametric polypolygon for gradients, the area covered by the returned XPolyPolygon2D should be monotonically decreasing with t (unless singularities in e.g. the resulting gradient are desired).
getColor
sequence< ColorComponent >
getColor( [in] double  t )
raises( ::com::sun::star::lang::IllegalArgumentException );
Description
Query the color value for the polygonal area at the specified parameter value.
Parameter t
Parameter value in the range [0,1]. During painting, this range is swept through starting from 0.
getPointColor
sequence< ColorComponent >
getPointColor( [in] ::com::sun::star::geometry::RealPoint2D  point )
raises( ::com::sun::star::lang::IllegalArgumentException );
Description
Query the color for a dedicated point in the plane.
Parameter point
The permissible parameter range for point is [0,1]x[0,1]
getColorSpace
XColorSpace
getColorSpace();
Description
Query the color space employed by this object
Returns
the color space the colors generated by this object are to be interpreted in.

Apache OpenOffice is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
