Examples

Translate a regions.CirclePixelRegion to photutils.aperture.CircularAperture:

>>> from regions import CirclePixelRegion, PixCoord
>>> from jdaviz.core.region_translators import regions2aperture
>>> region_shape = CirclePixelRegion(center=PixCoord(x=42, y=43), radius=4.2)
>>> regions2aperture(region_shape)
<CircularAperture([42., 43.], r=4.2)>
