boost::gil::static_generate

Equivalent to std::generate.

Synopsis

Declared in <boost/gil/color_base_algorithm.hpp>

template<
    typename P1,
    typename Op>
[[__always_inline__]]
void
static_generate(
    P1& dst,
    Op op);

Description

Example: Set each channel of a pixel to its semantic index. The channels must be assignable from an integer.

struct consecutive_fn {
    int& _current;
    consecutive_fn(int& start) : _current(start) {}
    int operator()() { return _current++; }
};
rgb8_pixel_t p;
int start=0;
static_generate(p, consecutive_fn(start));
assert(p == rgb8_pixel_t(0,1,2));
