NAME

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.
