Mapfile example
---------------

The following is the Mapfile used in this example ``mfa8.map`` ):


.. literalinclude:: ./mfa8.map
   :lineno-start: 1


Files are changed as follows:
-----------------------------

`Open the file: diff_mfa8_mfa6.html <./diff_mfa8_mfa6.html>`_


Now our MapFile contains a new object ``OUTPUTFORMAT`` . Within the
``MAP`` object defined by this object, and when used with the keyword
``IMAGETYPE``.

Depending on the compiled library of MapServer, you can have a variety
of output formats to choose from - the GD library provides ``PNG``
(8-bit and 24-bit), ``GIF``, ``JPEG``, ``WBMP`` , the GDAL library,
which sources many of MapServer’s input formats, and can also provide
output in ``PNG``, ``JPEG``, ``TIFF/GeoTIFF``, and other raster formats;
the pdflib library provides PDF output.

Have a look at your MAPFILE object by changing the keyword ``IMAGETYPE``
and experiment with ``OUTPUTFORMAT`` . It should be used as
``IMAGETYPE`` value (eg: ``IMAGETYPE png`` or ``PNG24 IMAGETYPE`` ), the
name of the output format.

Please consult the ``OUTPUTFORMAT`` object reference:
