<traceinc> trace increment for symbol posting (default 100)
<xsize> approximate image size, in pixels (default 500)
<padding> padding around image, in pixels (default 40)
<outfile> output image file name (default stdout)
<zgfout> optional output zgf file (default none)
<picout> optional output ZGF picture name (default none)
Note that the output file extension determines the output type. Note also the different
syntax for ZGF file output. See the next section for a simpler mechanism for generating
outlines over all volumes in a project.
Alternative Algorithm
An alternative 3D-only algorithm that does read every trace is also provided. Although it is
considerably slower, the standard invocation can handle internal holes within the survey,
non-contiguous pieces of seismic data, and decimated surveys. To test this algorithm, use
utility seisLTOexact, with similar arguments as seisLTO.
seisLTOexact owproj survey gtype seismic ?stride? ?delta?
?lineinc? ?traceinc? ?xsize? ?padding?
?outfile? ?zgfout? ?picout? ?zeroFlag?
The additional zeroFlag option will test for zero-valued traces.
Generating Outlines for all Volumes in a Project
To generate outlines for all volumes for a project with the default algorithm, use
seisLTO2D or seisLTO3D. This includes a clobber argument (3D only), allowing you
to regenerate all images (clobber) or only regenerate if the seismic has been modified
since the last live trace outline was created (noclobber).
Important note: noclobber does not work reliably with shapefile output where multiple
outlines are stored within a single file; using clobber with shapefile and zgf output is
therefore advised.
