| Introduction |
| ============ |
|
|
| `astropy.visualization` provides functionality that can be helpful when |
| visualizing data. This includes a framework for plotting Astronomical images |
| with coordinates with Matplotlib (previously the standalone **wcsaxes** |
| package), functionality related to image normalization (including both scaling |
| and stretching), smart histogram plotting, RGB color image creation from |
| separate images, and custom plotting styles for Matplotlib. |

| Scripts |
| ======= |
|
|
| This module includes a command-line script, ``fits2bitmap`` to convert FITS |
| images to bitmaps, including scaling and stretching of the image. To find out |
| more about the available options and how to use it, type:: |
|
|
| $ fits2bitmap --help |
