NAME
label3d - process a Raster3D scene containing labels
SYNOPSIS
label3d [-png [outfile.png ]] < infile.r3d > outfile.png
label3d -tiff [outfile.tiff] < infile.r3d > outfile.tiff
label3d is a shell script that processes a Raster3D input file
containing label descriptors (object types 10, 11, 12) into a TIFF or
PNG (default) image containing both the molecular graphics image and
the associated labels.
label3d uses the Raster3D utilities r3dtops and render, and requires
that both ghostscript and ImageMagick be installed.
ENVIRONMENT
Scratch files are created in directory TMPDIR, if defined, otherwise in
/usr/tmp. Font sizes are scaled by the value of the environmental
parameter FONTSCALE. FONTSCALE defaults to 3.
BUGS
The whole nature of label handling in Raster3D is not yet settled. It
would be much nicer if all the label processing were taken care of by
the render program itself.
The script assumes that the image is being prepared for printing at 300
dpi (r3dtops is called with -fontscale 3.0).
Labels always appear on top of the molecular graphics image, even
labels which should be occluded by a foreground object.
