Convert linear (raw) RGB into standardized sRGB.
#include <vigra/colorconversions.hxx>
Namespace: vigra
The sRGB color space is a slight improvement over the R'G'B' space. It 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 any of the primaries R, G, and B. By default, (this default can be overridden in the constructor). If both source and target color components are stored as unsigned char
, a look-up-table will be used to speed up the transformation.
