VkColors

This program generates colorful images using algorithms created by Jozsef Fejes.

Usage

VkColors can be invoked from the command line

VkColors [options]

There are multiple options to change the behavior of the image generator.

• --generator=[generator]

  This selects the algorithm to use in the image generator. Values that can be used are wave, coral, cpu-wave, and cpu-coral. Default is coral.

• --size=[width]x[height]

  This sets the size of the image. Valid values are any size between 1x1 and 4096x4096. Default is 512x512.

• --color=[source]

  This sets the method used to color the image. Values that can be used are shuffle and hue. Default is shuffle.

• --seed=[seed]

  This sets the seed used by the random number generator. Must be a 32-bit unsigned value. Default is based on system time.

Other options can be set, but this may result in strange behavior or crashing.

• --workgroupsize=[size]

  This sets the size of the compute work group used. Must be positive. Default is 64 on AMD hardware and 32 on anything else.

• --maxbatchabsolute=[size]

  This sets the maximum number of pixels that can be generated in one batch. Must be positive. Default is 64.

• --maxbatchrelative=[size]

  This sets the maximum number of pixels that can be generated, based on the current state of the image. Must be positive. Default is 1024.
