Basic Information on tvdisp
Purpose: Display an image on a TV device
Categories: visual display
TVDISP is a MIRIAD task to display an image on a TV device.
TVDISP does not clear the screen before it initializes the TV;
see TVINIT for this function.
Standard keyword in. See the help on in for more information.
Standard keyword region. See the help on region for more information.
NOTE: This region only permits simple bounding boxes.
The default is to display the entire image.
The minimum and maximum range used in scaling. The default is
to use the minimum and maximum values of the image.
The TV channel to display the image on. This can be 1 to 3 on
the IVAS; 1 to 2 on the MXAS or XMTV servers. The default is 1.
Only every INCR'th pixel is displayed. This can take from 1
to up to 3 values, giving the increment along the x, y, and z
axis, respectively. The default is chosen such that the selected
region of each image will fit on the screen.
This gives the coordinate where the lower left corner of the
image is displayed. The coordinate system typically runs from
1 to 1024 in x and y, the origin being in the lower left corner.
The default is to center the image on the screen.
Standard keyword server. See the help on server for more information.
There is no default for the server.
These indicate extra operations that may be performed. One or
more can be given. Possible values are:
fiddle Allow interactive modification of colour tables, zoom,
etc. NOTE: The Fiddle option currently only works
with the IVAS servers!
zoom Zoom in on the displayed images. NOTE: Zoom attempts
to display the bounding box of all of the displayed
images. If more than one channel was loaded, then
the zoomed display will be of the first channel.
movie Display the sequence of images as a movie.
NOTE: Movie will attempt to zoom onto one image and
then center the display step by step through each
following image (and then return back to the first
image to begin again). The rate at which the images
will change is a function of the cursor's X position.
The further to the left of the display that the cursor
is located, the faster the rate of change; the further
right, the slower. NOTE: some displays require a
mouse button press to identify the cursor position.
Functions to control the direction and style of motion
are available if the panel is present. If not, a
subset of functions will be available to the four
functions A - D (may also be keys F3 - F6).
