Creates a bitmap file from a FITS sky image. 
The dynamic range of the FITS image is represented in the output bitmap image by applying "stretch" transformation.
Matplotlib colormaps are used to represent resulting intensity.

---------

**Example:**

Here is an example of converting SDSS LegacySurvey image of NGC4388:

.. image:: legacysurvey_image.png
   :width: 70 %
   :alt: legacysurvey_image.png


Note that you can also visualize FITS files directly in galaxy with interactive interface based on AladinLite.
