#### NAME

mrcm - generate fractals with the MRCM algorithm

#### SYNOPSIS

**mrcm** **-help**
or
**mrcm** **[-infile** *string***]** **[-width** *integer***]** **[-height** *integer***]**
**[-depth** *integer***]** **[-border** *integer***]** **[-bw** *double***]**
**[-bh** *double***]** **[-L]** **[-term** *string***]** **[-inv]** **[-mag** *inte-*
*ger***]**

#### DESCRIPTION

An affine fractal is computed via the Multiple Reduction
Copy Machine Algorithm. The rules must be supplied from a
file with each line consisting of six values (A-F) such
that the values of A-D describe a 2x2 matrix (A, B; C, D),
while E and F describes a 2x1 column vector (E; F).

#### OPTIONS

**-infile** *string*
Data input file.
**-width** *integer*
Width of the plot in pixels.
**-height** *integer*
Height of the plot in pixels.
**-depth** *integer*
Depth of recursive calls.
**-border** *integer*
Number of pixels in border.
**-bw** *double*
Width of the seed box.
**-bh** *double*
Height of the seed box.
**-L** Draw an 'L' in each box?
**-term** *string*
How to plot points.
**-inv** Invert colors?
**-mag** *integer*
Magnification factor.

#### MISCELLANY

There is a shell script called 'ifscma' supplied with the
source code that has a simple interface that allows you to
reference sets of predefined rules by name. You may also
wish to see the author's book, "The Computational Beauty
of Nature," for some more examples.

#### BUGS

No sanity checks are performed to make sure that any of
the options make sense.
The maximum number of affine rules is determined by the
constant MAXRULES, which you may need to adjust under
exceptional circumstances.
