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 (you can click on the areas in the screenshot to navigate to the respective help pages):
- 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.
