-filename
"name" specifies a FITS format file to load and display.
-subsamplebool
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.
-sampmethodn (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
-usexshmbool
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.
-usexsyncbool
If true, try to use X synchronisation.
-verbosebool
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_colorsn-max_colorsn
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.
-xscalexs-yscaleys
Set the default scaling factors (default: 1).
-cameraname
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_factornumber
Set the scale factor for the zoom window (default 5 x the original image).
-colorramp_heighth
Set the height of the colorramp subwindow (default: 20).
-with_zoom_windowbool
If bool is true (default), add a zoom window.
-with_pan_windowbool
If bool is true (default), add a panning window.
-dozoombool
If true, turn on zoom window.
-disp_image_iconbool
If true, display a copy (view) of the image as an icon.
-drag_scrollbool
If true, set bindings to scroll with the middle mouse button.
-scrollbarsbool
If true, display scrollbars to scroll the image.
-portport
Default port for remote connections (0 means system chooses a
port).
-debugbool
Debugging flag: enables real-time simulation with testProg
(below).
-testprogpath
For testing: name of test program used to generate real-time updates (tRtd).
-intervaln
For testing: interval between updates in ms.
-with_perftestbool
If true, display performance tester utility in menu bar.
-with_warpbool
Option to warp the mouse pointer.
