NAME

 
rtd - real-time image display application

SYNOPSIS

 
rtd ?options? ?filename?

DESCRIPTION

 
The rtd application is used to diplay FITS images in real-time.
The application is based on "rtdimage", a Tk image extension
for displaying FITS images.

OPTIONS

 
-file name
        "name" specifies a FITS format file to load and
        display.

-subsample bool
        If bool is true, subsampling is used when shrinking
        the image, i.e.: if the image is shrunk by 1/3, only
        every third pixel is displayed. Otherwise, the maximum
        value is taken from the group of pixels.

-usexshm bool
        If bool is true (default), attempt to use X shared
        memory for the image display, if available. This
        improves performance considerably, but is only
        available when working on the system console.

-usexsync bool
        If true, try to use X synchronisation.

-verbose bool
        If bool is true, diagnostic messages are printed out
        to show what is going on internally (for debugging
        use).

-default_cmap
        This option sets the default colormap file to use when
        starting up.  Only the root of the filename should be
        specified for this option, for example: "ramp" for a grey
        level colormap.  For a list of available colormap files, see
        the colormaps directory in the rtd release.

-min_colors n
-max_colors n
        Specify the min and max number of colors to allocate before
        using a private colormap.

-default_itt
        This option is similar to -default_cmap, except it
        sets the default ITT (intensity transfer table) file
        to use at startup.  ITT files are also stored in the
        colormaps directory.

-xscale xs
-yscale ys
        Set the default scaling factors (default: 1).

-camera name
        Set the camera name for real-time image events:
        default: taken from the RTD_CAMERA environment
        variable, if set, otherwise set to RTDSIMULATOR, for
        simulation test mode.

-zoom_factor number
        Set the scale factor for the zoom window (default 5 x
        the original image).

-colorramp_height h
        Set the height of the colorramp subwindow (default: 20).

-with_zoom_window bool
        If bool is true (default), add a zoom window.

-with_pan_window bool
        If bool is true (default), add a panning window.

-dozoom bool
        If true, turn on zoom window.

-disp_image_icon bool
        If true, display a copy (view) of the image as an icon.

-drag_scroll bool
        If true, set bindings to scroll with the middle mouse button.

-scrollbars bool
        If true, display scrollbars to scroll the image.

-port port
        Default port for remote connections (0 means system chooses a
        port).

-debug bool
        Debugging flag: enables real-time simulation with testProg
        (below).

-testprog path
        For testing: name of test program used to generate real-time
        updates (tRtd).

-interval n
        For testing: interval between updates in ms.

-with_perftest bool
        If true, display performance tester utility in menu bar.

-with_warp bool
        Option to warp the mouse pointer.
