PostScript printing of SOM codebooks
A new program has been added to SOM_PAK 3.0 that
converts a SOM codebook into an PS/EPS file. Umat prints
maps with hexagonal or rectangular topology and can print multiple
labels on one unit. The EPS output should conform to the EPSF-3.0
specification from Adobe. It it
doesn't, let me know what's wrong with it so I can fix it.
Options
There is only one required option, -cin, the codebook
filename:
- -cin filename
- The name of the codebook file.
The optional parameters are:
- -o filename
- Save output to a different file. Default: Output
to standard output. The printing mode is determined from the
filename. If the name ends with .ps Postscript output
is used. The ending .eps specifies EPS output. This is
overridden by the -ps and -eps options.
- -border
- Draws borders around hexagons. Default: no borders.
- -onlylabs
- Prints only the labels.
- -portrait and -landscape
- Orientation of map, portrait or
landscape. Default: Depends on the
dimensions of the map. Maps with width greater than height will
be printed in landscape, others in portrait. Only affects PS
printing.
- -eps
- Selects EPS-printing. Will produce a EPS file suitable for
including in your documentations, for example, with LaTeX.
This option is the default
- -ps
- Selects PS-printing. Will produce a ready to print A4 size page.
- -W and -B
- Set white and black tresholds. Scales the grayscales so that
values from 0 to black treshold are printed black,
then grayscale goes linearly to white treshold values
higher than that are printed as white. Defaults: for
black: 0.0, for white 1.0.
- -font fontname
- Font used to print labels. This should be a name of a
PostScript font. Default: Helvetica
- -fontsize size
- Label font size. This is relative to the radius of the
hexagons/squares. Default: 1.0. The height of the
letters is about half of the height of the hexacons.
- -title string
- Selects the title to print on the top left corner of an PS
page. Default: codebook name.
- -paper papertype
- Select paper type. Supported values are A4 and A3.
Default: A4.
- -notitle
- Do not print title on PS page.
- -average
- Average umatrix.
- -median
- Median filter the umatrix.
- -headerfile filename
- Use alternate PostScript header file. Default: use the
one compiled in the binary (the same as header.ps in the
distribution).
- -swapx
- Swap x-coordinate in the image (swap right and left). [1]
- -swapy
- Swap y-coordinate in the image (swap up and down). [1]
Notes
- Footnote 1:
- Not available in the SOM_PAK-3.1 distribution. Works in our lab
only. Will be in the next public release.
