NAME
evolvotron_mutate - Render an evolvotron function tree to an image. SYNOPSIS
evolvotron_mutate < function_in.xml > function_out.xml evolvotron_mutate -g > function_out.xml DESCRIPTION
evolvotron_mutate either mutates an existing image function (saved to an XML file), or (with the -g option) creates a new image function. The mutation parameters and function weightings are the same as used by evolvotron in its default reset state. See the evolvotron user manual (accessible from the evolvotron application's Help menu) for more information on image functions. COMMANDLINE OPTIONS
-g Specifies that no function should be read from standard input. The output function is created at random. EXAMPLES
evolvotron_mutate -g | tee function0.xml | evolvotron_render function0.ppm evolvtron_mutate < function0.xml > function1.xml AUTHOR
