Description Ariel Constenla-Haile 2013-03-06 14:12:21 UTC

As reported in bug 121858 the GraphicProvider allows scaling images.

Internally, it calls Bitmap::Scale without setting the flag that indicates the method used for scaling. This defaults to BMP_SCALE_FASTESTINTERPOLATE as defined in <vcl/bitmap.hxx> Bitmap::Scale()

It should be possible to indicate in the FilterData the method for scaling the image.

The forth patch adds a new FilterData propery, named "Interpolation", that controls the method used in Bitmap::Scale. 
For this, a new constant group has been defined: css::graphic::Interpolation.

I'm not so sure about the naming, so suggestions are welcome.
