NAME
hp2ps - convert a heap profile to a P
OSTS
CRIPT graph
SYNOPSIS
hp2ps
[flags] [file][.hp]
DESCRIPTION
The program
hp2ps
converts a heap profile stored in
file
into a P
OSTS
CRIPT 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.
- -?
-
Print out usage information.
