Editing Raster image I/O (section)

==Converting RSF 2-D data to raster images==
If Madagascar has been compiled with TIFF support, <tt>sfbyte2tif</tt> can be used:
<bash>
< model.rsf sfbyte | sfbyte2tif > model.tif
</bash>
If Madagascar has been compiled with JPEG support, <tt>sfbyte2jpg</tt> can be used:
<bash>
< model.rsf sfbyte | sfbyte2jpg > model.jpg
</bash>
Then, another program can be used to convert the JPEG file to another format.
If [http://www.imagemagick.org ImageMagick] is present, it can be used to convert a RSF binary to almost any image format. In a SConstruct, the workflow would look like:
<python>
Flow('data.gray','data',
    '''
    transp |  # Make data in row-major order
    byte gainpanell=all allpos=y |  # Convert data to byte representation
    disfil col=1 number=n format="%02X" |  # Dump data in one column in ASCII-hex
    xxd -r -p  # Read ASCII output and convert it to binary form
    ''')

Flow('data.png','data.gray',
    '''
    convert -size %dx%d -depth 8 ${SOURCES[0]} ${TARGETS[0]}  # Run ImageMagick
    ''' % (n2, n1), stdin=0, stdout=0)
</python>

To output to another format, just change the extension in the last <tt>Flow()</tt> from .png to .gif or .jpg, for example. Create the output simply by running: <tt>scons data.png</tt>
