impression
this directory contains interactive tools for
creating painted representations of scanned-in photographs.
the interactive paint prog is called impression.
the other tools can be used to manipulate paintings stored as
a list of brush strokes. these brush stroke files are called
"sample sets" and usually have a suffix of ".ss".
`
The main paint program is:
impression it.rgb [-o it.ss] [-d dir.bw]
To give it a try type:
make demo
The program "ssshow" can be used to display a sample set
ssshow it.ss
The program "ssrender" can render a sample set at any resolution
ssrender it.ss rend.rgb 300 200
"ssrand" can be used to add noiseto brush stroke directions, positions, etc.
ssrand in.ss rand.ss mag -c -d -p -s
-c: color
-d: direction
-p: position
-s: size
"ssblend" linearly interpolates two paintings --
both paintings shud have about the same number of strokes
ssblend in1.ss in2.ss out.ss param
"sscross" cross disolves between two sample sets
sscross in1.ss in2.ss out.ss param
"sscat" concatnates several painings
sscat in1.ss in2.ss ... out.ss
"ssclip" clips brush stroke locations to a circle
ssclip in.ss out.ss
"ssgen" creates a rectangular array of brush strokes
ssgen out.ss nx ny
"ssprint" makes a textual description of a painting
ssprint in.ss
"sssample" samples an image to control brush stroke colors, directions or sizes
sssample in.ss out.ss in.rgb [-d] [-s]
"ssdensity" uses a b/w image to generate a set of sample positions with
varying density
"ssdomain" displays a sample set on the screen as a set of Dirichlet domains.
"sstops" converts a sample set to PostScript for printing.
you can scale the color, direction, poisition or size of strokes using
"ssscale"
ssscale in.ss out.ss scale
you can set the brush direction, size and shape for a whole sample set
using "ssset"
ssset in.ss out.ss val [-d -s -b]
you can sort brush strokes by color, direction, position and size
using "sssort"
sssort in.ss out.ss [-c -d -p -s]
OTHER PROGRAMS:
I suggest making "blurpix" ~40, but try small numbers also like 4.
