NAME
hp2ps - convert a heap profile to a POSTSCRIPT graph
SYNOPSIS
hp2ps [flags] [file][.hp]
DESCRIPTION
The program hp2ps converts a heap profile stored in file into a
POSTSCRIPT graph, sending the result to file.ps. By convention, files
to be processed by hp2ps have a .hp extension. However, for
compatibility with older versions of hp2ps, this extension can be
omitted. If file is omitted entirely, then the program behaves as a
filter.
OPTIONS
The flags are:
-d In order to make graphs more readable, hp2ps sorts the shaded
bands for each identifier. The default sort ordering is for the
bands with the largest area to be stacked on top of the smaller
ones. The -d option causes rougher bands (those reprsenting
series of values with the largest standard deviations) to be
stacked on top of smoother ones.
-b Normally, hp2ps puts the title of the graph in a small box at
the top of the page. However, if the JOB string is too long to
fit in a small box (more than 35 characters), then hp2ps will
choose to use a big box instead. The -b option forces hp2ps to
use a big box.
-e float[in|mm|pt]
Generate encapsulated POSTSCRIPT suitable for inclusion in LaTeX
documents. Usually, the POSTSCRIPT graph is drawn in landscape
mode in an area 9 inches wide by 6 inches high, and hp2ps
arranges for this area to be approximately centered on a sheet
of a4 paper. This format is convenient of studying the graph in
detail, but it is unsuitable for inclusion in LaTeX documents.
The -e option causes the graph to be drawn in portrait mode,
with float specifying the width in inches, millimetres or points
(the default). The resulting POSTSCRIPT file conforms to the
Encapsulated Post Script (EPS) convention, and it can be
included in a LaTeX document using Rokicki's dvi-to-POSTSCRIPT
converter dvips. hp2ps requires the width to exceed 2 inches.
-g Create output suitable for the gs POSTSCRIPT previewer (or
similar). In this case the graph is printed in portrait mode
without scaling. The output is unsuitable for a laser printer.
-p Use previous parameters. By default, the POSTSCRIPT graph is
automatically scaled both horizontally and vertically so that it
fills the page. However, when preparing a seires of graphs for
use in a presentation, it is often useful to draw a new graph
using the same scale, shading and ordering as a previous one.
The -p flag causes the graph to be drawn using the parameters
determined by a previous run of hp2ps on file.
-s Use a small box for the title.
-y Draw the graph in the traditional York style, ignoring marks.
