rtd - real-time image display application
rtd options filename
The rtd application is used to display FITS images in real-time. The application is based on "rtdimage", a Tk image extension for displaying FITS images.
-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. -sampmethod n (experimental) If option 'subsample' is false, the following methods can be used for displaying a shrunk image (i.e. an image with a scale factor < 1): 0 max value of all pixels in a NxN box (default) 1 min value of all pixels in a NxN box 2 mean value of all pixels in a NxN box 3 median value of all pixels in a NxN box 4 max value of pixels on a diagonal cross in a NxN box 5 min value of pixels on a diagonal cross in a NxN box 6 mean value of pixels on a diagonal cross in a NxN box 7 median value of pixels on a diagonal cross in a NxN box 8 median value of pixels in a chess-board like box 9 median value of a 3x3 box -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.
