Can pycoast create land/water masks?

[7yl4r]

Can pycoast be used to create landmasks?
It seems that the task of adding boundaries is much the same as creating a mask but I see no examples demonstrating this usage.

Easy creation of landmasks using this tool would be useful for my processing and likely many others.
I even came across this old issue on pyspectral mentioning the same.

What changes would be needed to allow pycoast to create masks?

AFAIK, pycoast can fill landmasses with a given colour, so in principle you could use it to make a land/sea mask yes. Now the question is how do you use it ? do you want to save it to some format to use in another program, or make this available to satpy for online masking in some composites ? The later is appealing to me in the way I use satpy in operation, but it would rather be a new composite class in satpy I suppose than some new functionality in pycoast.

I'm not using other parts of satpy (yet), so I was thinking of using a mask output file (png, tif, svg, or similar) to overlay onto an image produced by another pipeline.
