legends....

[Cliff Behrens]

Christine,

Here is a note that I posted a while ago that should help...but be careful of
quirks!


For those interested...

I have been using p.map.new in grass4.1beta to create a ppm file containing a
map with a legend.  Hardcopy is to be produced on a black-and-white PostScript
printer.  I was having problems rescaling the map to fit on  8 1/2 x 11 inch
paper and, when I finally solved this problem with help from this list, my
rescaled map did not include the bottom frame line.  So, here are the tricks...

Last summer I recall a hack posted by Raymond Venneker to restore the bottom
frame line (don't know why this wasn't included in 4.1, but it wasn't):

1)  edit  .../src.alpha/paint/Programs/p.map.new/cmd/map10.c as follows:

    change 

        Ppictsize (fullwindow.rows+extra_lines, pixels+MARGIN); 
    to
        Ppictsize (fullwindow.rows+extra_lines+MARGIN, pixels+MARGIN);  

    then recompile.

2)  To produce the PostScript map on a B&W PS printer (e.g., an Apple
    LaserWriter), rescaled to fit on 8 1/2 x 11 inch paper, issue the following:
      ppmtopgm 'yourfile.ppm' | pgmtops -s 0.5 | lpr -Pps10

    Of course, you will substitute the appropriate ppm file name and printer
    name for your installation.

Thanks to all of you who offerred help in unraveling this mystery!
