v12 v13 20 20 21 21 == Resampling the image == 22 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'''.22 The image can be resampled by linear interpolation of image luminosity on a grid, by selecting ''''Projection Object/plane''''.
