Changing the output resolution
The postscript writing routines filter out postscript commands for points that are
closer than the plot resolution. This dramatically reduces the size of some
postscript files.
The filter is configured to produce optimal file size for a 600 dpi printer. If you are
using a higher resolution printer, you can change the filter configuration by setting
the Tcl variable PlotFilterResolution. Its default setting is 0.2 (the units are
fractions of "points", which are 1/72 inch). To double the resolution, reduce
PlotFilterResolution by half:
set PlotFilterResolution 0.1
If PlotFilterResolution is set to too large a value, which corresponds to too coarse
a resolution, you will start to see "fuzzy" edges on analog transitions, and aliasing
of rapid digital signals. Smaller values (higher resolution) increase the size of the
postscript files.
When signal values are filtered out, the postscript output routines keep track of
what kinds of transitions occurred on the removed values. When a new plot point
is drawn, a glitch will also be drawn on the previous plot point showing the range
of excursion of the signal during that time. Thus the filtering does not remove any
information that would otherwise be visible on the plot.
