bplt

NAME

bplt - BSU program plots seismic traces. Formats: XWIN/WXT PS, XFIG, JPEG, PDF

SYNOPSIS

bplt [ -h |infile|idev|iorient|itype|1tr|Ltr|tmin|tmax|istyl|amp|. . .
percnt|xaxis|yaxis]

DESCRIPTION

Basic Seismic Utilities (BSU) plots seismic traces. This program uses either
the PLPLOT library or GNUPLOT, depending on how it is compiled. Web sites are
http://plplot.sourceforge.net or http://www.gnuplot.info
Output devices include X-window (interactive only with gnuplot), Post Script (PS),
Xfig CAD file, JPEG bitmap, and Portable Document Format (PDF).
Traces may be displayed as simple wiggle, variable area
(peak filled black, white trough), or variable area (peak filled black, grey
trough). Both PostScript and Xfig output can be scaled to desired axis lengths
in inches with the xaxis and yaxis parameters. JPEG images are specified in
100’s of pixels, so xaxis=5 yaxis=6 will produce a 500 x 600 pixel image if compiled
with gnuplot.
C-Language Version.

Options

0=X window (interactive if compiled with GNUPLOT)

1=PostScript

2=Xfig

3=JPEG

4=PDF
iorient orientation

0=landscape

1=portrait

0=trace number

1=offset

2=geophone z-coordinate

3=geophone x-coordinate

4=geophone y-coordinate

5=shot z-coordinate

6=shot x-coordinate

7=shot y-coordinate

0=wiggle trace

1=variable area (black peaks filled)

2=variable area (black peaks, grey troughs)

NOTE:
If invoked with no options, will prompt user for input parameters (except xaxis
and yaxis).

EXAMPLE:
bplt w001.seg 1 0 1 1 50 0 .1 1 100. 200. 5. 2.5

File w001.seg traces are plotted. The output will be a PostScript file,
landscape orientation, traces plotted by source-receiver offset, traces 1 to 50
plotted, traces plotted from 0 to 0.100 seconds, a value of 100 on a trace will
plot one trace spacing, traces clipped at +/- 1 trace, non-time axis plotted 5
inches long, time axis plotted 2.5 inches long.
