void Texture::export_ppm	(	const std::string &	filename,
		const unsigned int &	size_1,
		const int &	size_2,
		const std::vector< float > &	red_channel,
		const std::vector< float > &	green_channel,
		const std::vector< float > &	blue_channel
	)			[static]

Export ppm texture.

Parameters:

	filename,:	the name of the picture
	size_1,:	size in x direction
	size_2,:	size in y direction
	r_channel,:	red component (must be of size size_1*size_2)
	g_channel,:	green component (must be of size size_1*size_2)
	b_channel,:	blue component (must be of size size_1*size_2)

Values must be between [0,255]. Otherwise clamped.
