NAME
r3dtops - Raster3D to PostScript label conversion
SYNOPSIS
r3dtops [-fontscale xx] < infile.r3d > outfile.ps
r3dtops reads a Raster3D input file, selects out only the label
descriptors (object types 10, 11, 12), and creates a PostScript file
containing these labels and nothing else. The PostScript file can be
converted into a raster3 image by ghostscript and then recombined with
the the molecular graphics image produced by running the same input
file through render. This sequence of operations can be done by hand,
but is usually done automatically by the label3d script.
OPTIONS
-fontscale xx - It is problematic to interpret the font sizes requested
so that they produce the desired size on the eventual output device or
printer. By default the r3dtops program assumes that the eventual
output device is approximately 100dpi. However, printers generally
range from 300 to 1200 dpi. The parameter xx is a scale factor by which
the number of pixels per PostScript unit should be increased.
SPECIAL CHARACTERS
A small number of escaped characters are allowed in the label text
string. These may be useful for tweaking the position of your labels:
\n new line
\b backspace
\v vertical tab (move up 1/2 line)
BUGS
The whole nature of label handling in Raster3D is not yet settled. It
would be much nicer if all the label processing would be taken care of
by the render program itself.
