animmerger v1.0.0 - Copyright (C) 2010 Joel Yliluoma (http://iki.fi/bisqwit/)

Usage: animmerger [<options>] <imagefile> [<...>]

Merges animation frames together with motion shifting.

 --help, -h             This help
 --mask, -m <defs>      Define a mask, see instructions below
 --method, -p <mode>    Select pixel type, see below
 --looplength, -l <int> Set loop length for the LOOPINGLOG mode
 --version, -V          Displays version information

animmerger will always output PNG files into the current
working directory, with the filename pattern tile-####.png
where #### is a sequential number beginning from 0000.
You can convert them into a GIF animation with external
programs such as (ImageMagick and Gifsicle required):
   mogrify -format gif tile-????.png
   gifsicle -O2 -o animation.gif -l0 -d3 tile-????.gif

AVAILABLE PIXEL TYPES

  AVERAGE, long option: --method=average , short option: -pa
     Produces a single image. Each pixel
     is the average of all frames addressing that pixel.
  LAST, long option: --method=long , short option: -pl
     Produces a single image. Each pixel
     records the latest color addressing that pixel.
  MOSTUSED, long option: --method=mostused, short option: -pm
     Produces a single image. Each pixel
     records the color that most often occured in that location.
     Use this option for making maps!
  CHANGELOG, long option: --method=changelog, short option: -pc
     Produces an animation.
  LOOPINGLOG, long option: --methods=loopinglog, short option: -po
     Produces a time-restricted animation.
     Also called, "lemmings mode".
     Use the -l option to set loop length in frames.

DEFINING MASKS

  You can use masks to block out HUD / splitscreens
  so that it will not intervene with the animation.
  To define mask, use the --mask option, or -m for short.
  Mask syntax: x1,y1,width,height,colors
  Examples:
    -m0,0,256,32
       Mask out a 256x32 wide section at the top of screen
    -m0,0,256,32,FFFFFF
       From the 256x32 wide section at the top of screen,
       mask out those pixels whose color is white (#FFFFFF)
    -m16,16,8,40,000000,483D8B
       From the 8x40 wide section at coordinates 16x16,
       mask out those pixels whose color is either
       black (#000000) or dark slate blue (#483D8B)
