NAME
pnmframe - add borders to portable anymap
SYNOPSIS
pnmframe [-white|-black] [-l#] [-r#] [-t#] [-b#] [-d#] [-m#]
[pnmfile]
DESCRIPTION
Reads a portable anymap as input. Outputs a portable anymap
with extra borders. The colour of the borders can be set to
black or white (default black).
The left, right, top and bottom borders can be set with the
-l, -r, -t and -b option. In addition to this functionality
(from pnmpad), there are two new options, which are very
useful in an automatic printing environment. There are
printers (for example the Lasergraphics Film Recorder) which
have a built in scaling function. This is usually much
better than using a software-scaling tool. The problem is,
that the built in function knows nothing about some physical
restictions. The film recorder uses the whole film area. If
you put the slide in a frame, there may be a loss of
information, because the frame window is smaller than the
film area.
With the -d option you can give a denominator. The number of
columns and rows are divided by this value and the greater
value gives the new border, which is added around the
picture (newcolumns = columns + columns / denominator). All
above options (-l, -r, -t and -b) are ignored. If the
resulting border is 0, because the picture is to small, you
can use the -m option, which gives a 'minframe' value, which
means a minimum border size.
For the Lasergraphics Film Recorder with 2k resolution we
use -d32 -m2, which always gives a good result.
If you use the -m option in conjunction with the -l, -r, -t
and -b options, all values which are smaller than the
minframe value are set to the value you give in the -m
option. At the start of the program by default all missing
values are set to 0. This means for example, if you don't
use the -l option, the value is also set to the minframe
value. So the -m option is also useful for adding a border
to a picture.
