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. On Sun, 8 Dec, 2019, 5:30 PM , wrote:

- a function that checks whether the remaining capacity is at least n should be added. I suggest the name

bool can_fit( std::size_t n ) const noexcept;

although my previous choice of "has_capacity_for" has merit too.

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. -- Rob

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 https://lists.boost.org/boost-gil/2019/12/0362.php
