 == Getting the image histogram in a sub-region ==
-This is obtained by creating a contour object, a polygon, a rectangle or an ellipse, using '''Projection object/polygon''', '''Projection object/rectangle''' or '''Projection object/ellipse'''. Draw the contour with the mouse to plot the histogram of the image inside the contour.  To get the histogram of the region outside the contour, select thecheck box  '''[edit'''] in the frame '''Objects''' of '''uvmat'''. Then in the GUI '''set_object''', select 'outside' in the menu '''[!ProjMode'''] and press the button '''[REFRESH'''].

 == Resampling the image ==
-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'''].
