This interface allows you to draw polygons having any number of sides and having vertices that lie at integer pixel coordinates . Note that _ bkgd.fit / _ ff.fit is evaluated at the same pixel position as the output pixel , even though the output pixel coordinates are in the FARF and the _ bkgd.fit and _ ff.fit files have been transformed into raw coordinates . A good feature they all have is dynamic layout ; none of them relies on pure Cartesian pixel coordinates , although it is possible to arrange widgets with them in this way . Using celestial world coordinate system information in the image headers , sregister computes a grid of matched pixel coordinates in a reference and input image , uses the coordinate grid to compute the coordinate mapping from the reference to the input image , uses the coordinate mapping to compute the output image grey levels by interpolating in the input image at the position of the mapped reference pixels , and copies the reference image celestial world coordinate system to the output image .
