That is a very good idea :) Thank you very much ! Eloi. 2010/1/14 Lubomir Bourdev <lbourdev@adobe.com>
GIL core provides channel-level equivalents for some STL algorithms, including std::fill. These have the “static_” prefix since they are compile-time recursive:
rgb8_pixel_t p; static_fill(p, 10); assert(p == rgb8_pixel_t(10,10,10));

Depending on if you can rely on a boost gil extension, numeric/pixel_numeric_operations.hpp has a zero_channels function.
This would give (untested) :
comp_pixel_t black; zero_channels( black ); fill_pixels( tmpv, black );

Okay, I see. But the problem is that I don't know the pixel number of channel. It have to be full generic. That's why I am trying this (unsuccessfully): comp_pixel_t black; color_convert( bgil::gray8_pixel_t( 0 ), black ); fill_pixels( tmpv, black);
