Files are changed as follows:

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:

//www.mapserver.org/mapfile/outputformat.html#outputformat
