GLOBE Claritas Plotting
GLOBE Claritas uses the HP-RTL (Hewlett-Packard Raster Transfer Language) as its basic raster language - no CGM metafiles or interpreters are used or required. Claritas includes filters to convert from HP-RTL to a variety of other common graphics formats, eg TIFF, PostScript and Versatec. However if you have HP DesignJet plotters, the raster files output from Claritas can be spooled directly to the plotter.
Claritas produces its hardcopy output using a collection of processor modules (RASTER, PLOTLABEL, TOPLABEL and SIDELABEL) which are merged together at the end of the job to form one raster file. RASTER can create mono variable-area/wiggle-trace output, or colour variable-density output. Other related modules include the HORIZONS and BACKGROUND processors which can add digitised horizon information to the plot (either as an overlay or underlay to the seismic traces) or colour behind the seismic traces according to some seismic attribute, such as instantaneous amplitude, or velocity.
Seismic traces can optionally be positioned according to a seismic trace header value such as offset, rather than the usual sequential plotting.
