       QFitsView - FITS file viewer based on DPUSER

SYNOPSIS

       QFitsView filename

DESCRIPTION

       QFitsView  is  a  FITS  file  viewer.  It can display one, two, and three-dimensional FITS
       files. It is written completely in C++ and uses the Qt  widget  library,  which  makes  it
       available  for  all  major  platorms:  Windows, MAC OS-X, and many Unix variants. Its main
       window consists of the following areas:

       •   At the top, a toolbar which provides quick access to commonly used actions

       •   At the left:
            - information of the pixel under the cursor (pixel coordinates, pixel value  and  WCS
           coordinates)
            - a magnifier
            - a total view of the image

       •   At the bottom, the DPUSER command and output window

       •   Also  at  the  bottom,  in  case  a FITS datacube is displayed, the spectrum under the
           cursor

       •   The central part of the window shows the actual image

       QFitsView has three modes of operation, depending of what kind of data is being displayed.
       In case of one-dimensional data, the data are shown in an x-y plot. Two-dimensional images
       are shown in the main window. Three-dimensional data cubes can be displayed in  a  variety
       of  ways,  the  third  dimension  is  shown again as a x-y plot at the bottom of the image
       display.

BUGS

       The Debian version of dpuser was compiled without PGXTAL support which is not supported by
       the underlying graphics library.
