NAME

gcpSetIntensity, gcpGetIntensity - Manipulate Lighting

SYNOPSIS

 #include <ggi/gcp.h>
 
 gcp_pixel gcpSetIntensity(ggi_visual_t vis,
               const gcp_pixel *pix1, const gcp_pixel *light_color);
 gcp_pixel gcpGetIntensity(ggi_visual_t vis,
               const gcp_pixel *pix1, const gcp_pixel *pix2);

DESCRIPTION

gcpSetIntensity sets the intensity for a gcp_pixel(3).

gcpGetIntensity extracts the intensity of a gcp_pixel(3).

RETURN VALUE

gcpSetIntensity returns a gcp_pixel(3) with the new light itensity.

gcpGetIntensity returns a gcp_pixel(3), that corresponds the light_color argument of gcpSetIntensity. The pix1 is the same 'basecolor' passed to gcpSetIntensity and pix2 corresponds the return value of gcpSetIntensity.
