double QgsPalLayerSettings::scaleToPixelContext ( double  size,
const QgsRenderContext &  c,
SizeUnit  unit,
bool  rasterfactor = false 
) const

Calculates size (considering output size should be in pixel or map units, scale factors and optionally oversampling)

Parameters
sizesize to convert
crendercontext
unitSizeUnit enum value of size
rasterfactorwhether to consider oversampling
Returns
size that will render, as double
Note
added in 1.9, as a better precision replacement for sizeToPixel
