               infile=None,displaytype=None,channel=None,zoom=None,outfile=None,

               outscale=None,outdpi=None,outformat=None,outlandscape=None,gui=None

        The imview task will display images in raster, contour, vector or

        marker form.  Images can be blinked, and movies are available

        for spectral-line image cubes.  For measurement sets, many

        display and editing options are available.

​

        examples of usage:

​

        imview

        imview "myimage.im"

        imview "myrestorefile.rstr"

        imview "myimage.im", "contour"

​

        imview "'myimage1.im' - 2 * 'myimage2.im'", "lel"

        Executing imview( ) will bring up a display panel

        window, which can be resized.  If no data file was specified,

        a Load Data window will also appear.  Click on the desired data

        file and choose the display type; the rendered data should appear

        on the display panel.

​

        A Data Display Options window will also appear.  It has drop-down

        subsections for related options, most of which are self-explanatory.

        The state of the imview task -- loaded data and related display

        options -- can be saved in a 'restore' file for later use.

        You can provide the restore filename on the command line or

        select it from the Load Data window.

​

        See the cookbook for more details on using the imview task.
