Re: Proposal for Hints Information

I'm thinking about the uses cases here and let me try a straw man … 

If there is an aspect ratio, specified, meeting that constraint is the highest priority.

If there is a max height or width set, meeting that constrain is the next highest priority.

If there is a min height or width set, meeting that constraint is the lowest priority.

All constraints being meant, select the solution with the largest number of pixels.


For the cases I could think of of being "realistic" use cases - these rules seemed to work. Thoughts on if something as simple of this would not work? different set of rules ?

In fact, I suspect authors will want not just single priority flags but rather an ability to give a priority list, e.g., height_bound is more important than best_aspect, which is more important than fit_height, but width_bound, best_fit, and fit_width are unacceptable.

For example, is 176 by 144 bigger or smaller than 160 by 160. What I would propose is that we order them based on the number of pixels. So 176 * 144 = 25344 which is smaller than 160 * 160 = 25600. If the number of pixels is the same then we pick the one that is wider is considered bigger.
