PS_EVOL(1) User Contributed Perl Documentation PS_EVOL(1)NAMEps_evol - Perl script to fine-tune A4 PostScript drawings
SYNOPSIS
vi plant.ps
ps_evol plant.ps > p2.ps
DESCRIPTIONps_evol is mainly intended as a demo script illustrating the text_evol
funtion in Math::Evol.pm. It assumes you have something like GhostView
which allows you to view PostScript files.
It creates a temporary PostScript file, then repeatedly generates eight
variants of the original file, scales them smaller, numbers them, and
displays them in a 3x3 array. The original is in the middle, as number
5. It asks the user which variant they prefer, then uses that as the
original for the next iteration. When the user decides to call a halt,
the latest preferred variant is written to the standard output.
The parameters to be varied in the PostScript file must be marked out
by special comments, such as
/gray_sky .87 def % evol step 0.05 min 0.0 max 1.0
See perldoc Math::Evol for more details, and as an example the
PostScript file plant.ps, included with the distribution.
Version 1.05, #COMMENT#
DEPENDENCIES
Uses the CPAN module Term::Clui.pm to dialogue with the user.
