static constexpr scale v1::geo::scale< D >::uniform ( extent< float, E > src_extent, extent< float, F > dst_extent )

inlinestaticconstexprnoexcept

Get a uniform-scale-transform to scale an extent to another extent.

Parameters

src_extent	The extent to transform
dst_extent	The extent to scale to.

Returns

a scale to transform the src_extent to the dst_extent.
