Paintable.computeConcreteSize

void computeConcreteSize(double  specifiedWidth,  double  specifiedHeight,  double  defaultWidth,  double  defaultHeight,  out  double  concreteWidth,  out  double  concreteHeight)

Compute a concrete size for the [gdk.paintable.Paintable].

Applies the sizing algorithm outlined in the

CSS Image spec

to the given paintable. See that link for more details.

It is not necessary to call this function when both specified_width and specified_height are known, but it is useful to call this function in GtkWidget:measure implementations to compute the other dimension when only one dimension is given.

Parameters

`specifiedWidth`	the width paintable could be drawn into or 0.0 if unknown
`specifiedHeight`	the height paintable could be drawn into or 0.0 if unknown
`defaultWidth`	the width paintable would be drawn into if no other constraints were given
`defaultHeight`	the height paintable would be drawn into if no other constraints were given
`concreteWidth`	will be set to the concrete width computed
`concreteHeight`	will be set to the concrete height computed
