AffineTransform

class prose.blocks.alignment.AffineTransform(stars=True, data=True, inverse=False, output_shape=None, name=None, rotation=None, translation=None, scale=None, same_shape=True)

Apply an affine transformation to image and/or stars

read

• rotation : Image.header['TROT']

• translation : Image.header['TDX'], Image.header['TDY']

• scale : Image.header['TSCALEX'], Image.header['TSCALEY']

write

• Image.transform

• Image.inverse

• Image.stars_coords

Parameters:

• stars (bool, optional) – whether to apply transform to Image.stars_coords, by default True

• data (bool, optional) – whether to apply transform to Image.data, by default True

• inverse (bool, optional) – whether to apply inverse transform, by default False

• output_shape (tuple-like, optional) – shape of the transformed image. By default None, conserving the orignial shape
