USAGE: hexagons [-d dimension] [-c cellsize] [-e edgecolor] [-t thickness] infile outfile
USAGE: hexagons [-h or -help]

-d ... dimension .... square size of the output image; default is the
..................... minimum dimension of the input
-c ... cellsize ..... square size of hexagon cellsize; pixels or percent with
..................... % symbol included; default is 1/3 of dimension; the
..................... minumum size is the equivalent of 50 pixels and the
..................... maximum size is dimension (100%)
-e ... edgecolor .... edge color assigned to border of hexagons; any valid
..................... IM color is allowed; default is no edge color
-t ... thickness .... thickness of edges in pixels; integer>=0; default=0

PURPOSE: To create a hexagonal grid of the randomly rotated input image.

DESCRIPTION: HEXAGONS creates a hexagonal grid of scaled and randomly rotated copies of the input image. The input image will be center cropped to its minimum dimension for use in the hexagons.

ARGUMENTS:

-d dimension ... DIMENSION is the square size of the output image. The default is the minimum dimension of the input.

-c cellsize ... CELLSIZE is the square size of the hexagon cells. Units are either pixels or percent with % symbol included. The default is 1/3 of the dimension value. The minumum allowed size is the equivalent of 50 pixels and the maximum size is the dimension argument (i.e. 100%).

-e edgecolor ... EDGECOLOR is the color assigned to edges (border) of the hexagons. Any valid IM color is allowed. The default is no edge color.

-t thickness ... THICKNESS of edges in pixels. Values are integers>=0. The default=0 (no edge color).

CAVEAT: No guarantee that this script will work on all platforms, nor that trapping of inconsistent parameters is complete and foolproof. Use At Your Own Risk.

What the script does is as follows:

  • Creates a hexagonal grid of the desired cell size tiled out
    to the output size as an array of hexagons
  • Creates a random set of rotation angles
  • Scales the input image sqrt(2) times the desired cell size
  • Creates a hexagonal mask of the desired cell size
  • Creates randomly rotated copies of the scaled image
    and assigns page offsets according to the hexagonal grid spacing
  • Flattens all the rotated, scaled and offset copies
