SYNOPSISpcv-Toutput_plugin [-Rrender_plugin] [options] file.pcv ['filter']
DESCRIPTIONpcv allows to compile PCV files into a plugin choosen format, such as
svg, csv, png or other.
-Tplugin Replace 'plugin' with a output plugin name. See plugin section
-Rplugin Replace 'plugin' with a render plugin name. See plugin section
options can be either one or several among:
-A argument Provides arguments to the render and output plugin
-Warg Use Picviz with a special keyword. See keywords section
-a Displays all text along with lines
-r...(rrr) Increases image height and width
-d Activates debug mode
-l Skip learning mode
The filter parameter is explained in the filter section below.
PLUGINS
Output
Output data in the wanted file format. Available plugins are:
svg
plplot
csv
sdl
pngcairo
debug
Render
Modify data rendering. Available plugins are:
heatline: possible arguments (-A): virus
debug
KEYWORDS
Keywords are special parameters given to picviz to use a library along
with parsing and rendering. This is deactivated by default because it
makes the program slow, but it may be very usefull in certain cases.
Following keywords are accepted:
pcre: activates pcre pattern matching for filtering (pcv -Tsvg -Wpcre
file.pcv 'show value = ".*foo.*" on axis 1')
FILTERpcv allows filtering to choose data you want to see displayed. When the
pcv language parser is called, a Pcv Image Filter (PIF) is applied. It
allows to filter either before any data is calculated (data filter),
once calculated and before adding the line to the image (pre line
filter) or, once other lines have been added and ask for specific
removales (post line filter).
Relations
Filter relation can be either:
= equal
!= not equal
< less than
> greater than
<= less or equal
>= greater or equal
Selecting plot value
plot: Will select the value, as plotted by the engine. Accepted values
can be the y position on the axis or the relative percentage.
'show plot > 100 on axis 3': will display only lines which have their
plot on the axis 3 greater than 100 can be called like this:
Example: pcv-Tsvg file.pcv 'show plot > 100 on axis 3'
By default, the image height is 500 pixels, so this filter is
equivalent than > 100:
'show plot > 20% on axis 3'.
Pattern matching
Values can be selected, either with their original text string, or by
using pattern matching. By default, pattern matching is not activated.
Pattern matching activated is done with -Wpcre argument. To filter
values with [0-9][aA].*, you can type:
pcv-Tsvg file.pcv -Wpcre 'show value = "[0-9][aA].*" on axis 1'.
Note that with string comparisons (with value), only the equal (=)
relation is accepted.
EXAMPLEpcv-Tsvg file.pcv
pcv-Tpngcairo file.pcv -rrrr -a > file.png
pcv-Tpngcairo -Rheatline -Avirus file.pcv > file.svg
