This is a trivial benchmark designed to compare GraphicsMagick and
ImageMagick performance with file 'convert' operations. This benchmark is
written by Bob Friesenhahn <bfriesen@graphicsmagick.org> and is intended to
make it clear why you should be using GraphicsMagick rather than
ImageMagick.

Requirements in order to run the benchmark

  Unix shell
  GraphicsMagick
  ImageMagick
  Ghostscript
  ZSH shell (to run command for consistent timing output)

To use simply do

  ./runbench.sh TIFF

or use any other writeable format designator in order to test with that
format.  If multiple formats are listed, then the benchmark will be run for
each format.

The first time the benchmark is executed, the included golfer.ps and tiger.ps
are used to generate master images used for the test.  This can take some
time so be patient.

The runbench.sh file is just a shell script so it can be edited to taste.
Configurable items:

CONVERT1
  First 'convert' command to test

CONVERT2
  Second 'convert' command to test

DENSITY
  Resolution to render the test files with.  The default is 600 but
  if you have lots of memory, it is useful to test with 1200 and
  2400 as well.

OPERATION
  An image processing operation to perform while converting.
