Re: [boost] Boost GIL

8 Dec 2019


      Thanks a lot for forwarding my email to the boost GIL list. I will check it
out.
What I meant by conversion, however was primarily converting an image to
negative and greyscale. As you may already know, the two pf them are pretty
similar and OpenMP has shown how incredibly fast the process can be using
more threads. I just feel GIL would benefit a lot from using parallel
programming.

I suggest the simpler "fits".

Make this a free function template and you can use it with other
containers:
template <typename CONTAINER>
bool can_fit( const CONTAINER& C, typename CONTAINER::size_type n )
noexcept
{
   return C.capacity() - C.size() >= n;
}
That's a nice idea, especially with the name "fits". :) However, if you
reverse the parameters, "fits_in" would be a better name as it indicates
the argument order.

I feel the idea was the same, but a lot of improvement can be made.
Good, sounds like you may have a plan in mind

Also, there was no provision for image conversion, which I feel
Please, you need to be more specific here.
What kind of conversion do you mean: color, channel/pixel type, format,...?
p.s. I forwarded your post to the GIL mailing list
