image_scatter_facets
- ska_sdp_func_python.image.gather_scatter.image_scatter_facets(im: Image, facets=1, overlap=0, taper=None) List[Image][source]
Scatter an image into a list of subimages using the image_raster_iterator.
If the overlap is greater than zero, we choose to keep all images the same size so the other ring of facets is ignored. So if facets=4 and overlap > 0 then the scatter returns \((facets-2)^2 = 4\) images.
- Parameters:
im – Image
facets – Number of image partitions on each axis (2)
overlap – Number of pixels overlap
taper – Taper at edges None or ‘linear’
- Returns:
list of subimages
