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.
