    1818== Resampling the image ==
    19 The image can be resampled by linear interpolation of image luminosity on a grid, by selecting '''[Projection object/plane]'''. Then on the GUI '''set_object''', select 'interp_lin' in the menu '''[!ProjMode]'''. Set the mesh in x and y by the edit boxes '''[num_DX]''' and '''[num_DY]''', for instance with values 10, and press '''[REFRESH]'''. The image interpolated on this coarse grid is then displayed. It is also possible to reduce the range of x and y by the edit boxes '''[num_RangeX_1]''' and '''_2''' and '''[num_RangeY_1]''' and '''_2'''. Finally it is also possible to rotate the projection grid by setting the angle (in degrees) in the edit box '''[num_Angle_3'''].
