Expand description

Main enum structure descripting a WCS object Once created, the user can proceed two operation on it

The projection of a (lon, lat) tuple onto the image space. Results are given in pixels
The unprojection of a (x, y) tuple given in pixel coordinates onto the sphere. Results are given as a (lon, lat) tuple expressed in degrees

Variants§

§

CooSip(Img2Celestial<Coo, WcsWithSipImgXY2ProjXY>)

Implementations§

source §

impl WCSProj

source

pub fn new(header: &Header<Image>) -> Result<Self, Error>

Create a WCS from a specific fits header parsed with fitsrs

Param

header: Header unit coming from fitsrs. This contains all the cards of one HDU.

source

pub fn proj_lonlat(&self, lonlat: &LonLat) -> Option<ImgXY>

Project a (lon, lat) 3D sphere position to get its corresponding location on the image The result is given a (X, Y) tuple expressed in pixel coordinates.

Param

lonlat: the 3D sphere vertex expressed as a (lon, lat) tuple given in degrees

source

pub fn unproj_lonlat(&self, img_pos: &ImgXY) -> Option<LonLat>

Unproject a (X, Y) point from the image space to get its corresponding location on the sphere The result is given a (lon, lat) tuple expressed in degrees.
