- Form: ROUND dest source [PA=f] [E=e] [C=(r,c)] [NORM]
[SINC]
-
- dest
- is the destination image buffer. It does not need
to exist beforehand.
- source
- is the image buffer to transform
- PA
- is PA of object's major axis
- E
- gives its ellipticity = 1-b/a
- C
- gives its row and column center
- NORM
- renormalize pixel intensities
- SINC
- use high-accuracy sinc interpolation.
ROUND will deproject an image by assuming that the true shape of the object
is a circle projected into an ellipse of a given position angle,
ellipticity (1-b/a) and center. Creates a new image in the `dest' buffer
from the original image in the `source' buffer.
The SINC keyword instructs ROUND to use high-accuracy sinc interpolation
instead of the default bilinear interpolation algorithm.
The NORM keyword is used to renormalize the pixel intensities (surface
brightness/pixel) in the transformed image.
