This class provides class methods for Cartesian projection.
Methods
ang2xy(theta[, phi, lonlat, direct]) | From angular direction to position in the projection plane (Cartesian). |
get_center([lonlat]) | Get the center of the projection. |
get_extent() | Get the extension of the projection plane. |
get_fov() | |
get_proj_plane_info() | |
ij2xy([i, j]) | From image array indices to position in projection plane (Cartesian). |
mkcoord(coord) | |
projmap(map, vec2pix_func[, rot, coord]) | Create an array containing the projection of the map. |
set_flip(flipconv) | flipconv is either ‘astro’ or ‘geo’. None will be default. |
set_proj_plane_info(xsize, ysize, lonra, latra) | |
vec2xy(vx[, vy, vz, direct]) | From unit vector direction to position in the projection plane (Cartesian). |
xy2ang(x[, y, lonlat, direct]) | From position in the projection plane to angular direction (Cartesian). |
xy2ij(x[, y]) | From position in the projection plane to image array index (Cartesian). |
xy2vec(x[, y, direct]) | From position in the projection plane to unit vector direction (Cartesian). |
