# healpy.projector.CartesianProj.projmap¶

CartesianProj.projmap(self, map, vec2pix_func, rot=None, coord=None)

Create an array containing the projection of the map.

Input:
• vec2pix_func: a function taking theta,phi and returning pixel number

• map: an array containing the spherical map to project,

the pixelisation is described by vec2pix_func

Return:
• a 2D array with the projection of the map.

Note: the Projector must contain information on the array.
