no crop nor embed about sharp

[lovell]

I may need a worked example to understand what you're trying to achieve. Are you looking for a hybrid approach where the image is partially resized then any remainder cropped? Could your idea relate to not maintaining aspect ratio?

Width and height are currently both optional. After resizing, if the width and height already exactly match the required dimensions then the crop/embed step is skipped.

It maintains aspect ratio but the arguments passed to resize are a "max", not a perfect match.
For example, a 4000x3000px image resized with (200, 200) will be 200x150px

Got it, thanks. What you suggest is (I think) the default behaviour of GraphicsMagick's geometry option.

It would be hard to provide a less intuitive API for this than GM's punctuating ^!@...

Anyway, this max() option would be another canvas setting, mutually exclusive of the existing crop() and embed*() methods/settings/options. Internally options.canvas is represented as a single character String to make the transition from JavaScript to C++ as simple as possible.
