An image of the photon distribution can be output, independent of the
type of filtering of the rays. The image marix may be output as either
ascii text, an /rdb
compatible database, or as a binary
file. In all cases it is possible to prepend a header to the output
describing the size of the image (the number of rows and columns) and
its dimensions. The binary image may be written in either single or
double precision, and may be made compatible with either C or Fortran
(unformatted records) style binary input. See Image Formats, for
more details. spatquant
can be instructed to output the size of
the image to stderr
in sparse mode (see Misc Parameters,debug
). Normally the ray weights as accumulated are
output, but they may be divided by the area of the bins, to provide
their surface density (see Binning Parameters, norm_area
).
