       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.
