Structure of defining values for the ParametricPolyPolygon.
const css::uno::Sequence< css::uno::Sequence< double > > maColors
Gradient colors.
const GradientType meType
Type of gradient to render (as e.g. linear grads are not represented by maGradientPoly)
const ::basegfx::B2DPolygon maGradientPoly
Polygonal gradient shape (ignored for linear and axial gradient)
Values(::basegfx::B2DPolygon aGradientPoly, const css::uno::Sequence< css::uno::Sequence< double > > &rColors, const css::uno::Sequence< double > &rStops, double nAspectRatio, GradientType eType)
const double mnAspectRatio
Aspect ratio of gradient, affects scaling of innermost gradient polygon.
const css::uno::Sequence< double > maStops
Gradient color stops.
