Crop image based on polygon

Hi! Thanks.

I don't know if I would do that at the RasterIO Window level. After all, COGS are still an image format, and all image formats I know are based on rectangles...

Something that could be done is to trim the data before converting it into a PNG file, applying rasterio.mask. See, for example, this thread.

I didn't try this, but my guess is that something like this line should work:

out_image, out_transform = rasterio.mask.mask(subset, geometry, filled = True)

show(out_image)
