The sed command looks at a line and filters out only the part that has this pattern "(number)x(number)" punctuated by underscores. So in this pattern
the regex ".*_" is the entire line to the left of the first 300 as is the "_.*" to the right of the second 300. The [0-9][0-9]* filters out only numbers and the "x" and "_" are taken literally...

ppmpat(1) General Commands Manual ppmpat(1)NAME
ppmpat - make a pretty pixmap
SYNOPSIS
ppmpat -gingham2|-g2|-gingham3| -g3|-madras|-tartan| -poles|-squig|-camo| -anticamo width height
DESCRIPTION
Produces a portable pixmap of the specified width and height, with a pattern in it.
This program is mainly to demonstrate use of the ppmdraw routines, a simple but powerful drawing library. See the ppmdraw.h include file
for more info on using these routines. Still, some of the patterns can be rather pretty. If you have a color workstation, something like
ppmpat -squig 300 300 | ppmquant 128 should generate a nice background.
OPTIONS
The different flags specify various different pattern types:
-gingham2
A gingham check pattern. Can be tiled.
-gingham3
A slightly more complicated gingham. Can be tiled.
-madras
A madras plaid. Can be tiled.
-tartan
A tartan plaid. Can be tiled.
-poles Color gradients centered on randomly-placed poles. May need to be run through ppmquant.
-squig Squiggley tubular pattern. Can be tiled. May need to be run through ppmquant.
-camo Camouflage pattern. May need to be run through ppmquant.
-anticamo
Anti-camouflage pattern - like -camo, but ultra-bright colors. May need to be run through ppmquant.
All flags can be abbreviated to their shortest unique prefix.
REFERENCES
Some of the patterns are from "Designer's Guide to Color 3" by Jeanne Allen.
