    44Projection objects are used in various ways for image or field analysis, as shown in the following examples. Let us choose now a color image as input UVMAT_DEMO02_color/, for instance '/images/frame1.jpg'. (accessible on http://servforge.legi.grenoble-inp.fr/pub/soft-uvmat/)
     
    66We notice in this example that the frame index '1' directly follows the '''[!RootFile]''' 'frame' (without separator '_'), so '''[!NomType]''' is '1'. By moving the mouse over the image, we notice that the luminosity A has three color components rgb (red, green, blue). Similarly the histogram has three curves.

    910Create a line by the menu bar command ''''Projection Object/line''''. A new GUI 'set_object' appears on the right side, with default settings Type='line', !ProjMode='projection'.
    1011Draw a line with the mouse, left hande side button to mark the beginning and end of the line. The luminosity profile, with the three rgb components, appears in a new GUI ''''view_field''''. The line can be moved with the mouse, or by directly introducing the coordinates of the line in the table '''[Coord]''' of the GUI '''set_object'''.
