USAGE: v [-help]

-r ..... rows ....... number of rows of tiles; integer>0; maximum of 16
..................... total tiles in rows and columns; default=2
-c ..... cols ....... number of columns of tiles; integer>0; maximum of 16
..................... total tiles in rows and columns; default=2
-c1 .... colors1 .... space delimited set of colors for the first tile;
..................... Any set of opaque IM colors are allowed; Number of
..................... colors must be at least 2; default=2

etc up to

-c16 ... colors16 ... space delimited set of colors for the last tile;
..................... Any set of opaque IM colors are allowed; Number of
..................... colors must be at least 2; default=2
-i ..... interp ..... interpolation method for colorizing; Any valid IM
..................... interpolation method allowed; default=nearestneighbor
-g ..... gain ....... gain amount for colorizing; float>=0; default=3

PURPOSE: To create a pop art effect image.

DESCRIPTION: POPART creates an pop art style image. This image is a montage of images, each colored with different sets of colors from the input image. The default is a 2x2 montage with 2 colors each.

ARGUMENTS:

-r rows ... number of ROWS of tiles. Values are integers>0. A maximum of 16 total tiles in rows and columns combined. The default=2.

-c cols ... number of COLS of tiles. Values are integers>0. A maximum of 16 total tiles in rows and columns combined. The default=2

-c1 colors1 ... COLORS1 are a space delimited set of colors for the first tile. Any set of opaque IM colors are allowed. The number of colors must be at least 2. If not specified, random colors will be created. The default=2. Note: do not add spaces in rgb(...) color triplets.

etc up to

-c16 colors16 ... COLORS16 are a space delimited set of colors for the last tile. Any set of opaque IM colors are allowed. The number of colors must be at least 2. If not specified, random colors will be created. The default=2. Note: do not add spaces in rgb(...) color triplets.

-i interp ... INTERP is the interpolation method for colorizing; Any valid IM interpolation method is allowed. The default=nearestneighbor.

-g gain ... GAIN amount for colorization. Values are floats>=0. The default=3.

What the script does is as follows:

  • Computes random colors for each tile specified
  • Createa a color lut from the colors
  • Applies each color lut to its respective tile image
  • Montages the tile images together
