Convert standardized sRGB into non-linear (raw) RGB.
#include <vigra/colorconversions.hxx>
Namespace: vigra
The sRGB color space is a slight improvement over the R'G'B' space. Is is now a widely accepted international standard (IEC 61966-2.1) which is used by most consumer products (digital cameras, printers, and screens). The functor realizes the transformation
where C is one of the color channels R, G, or B, and unsigned char
, a look-up-table will be used to speed up the transformation.
Traits defined:
