# demo for creating GIF animation and illustrating saving images to

# file one pixel to one pixel

#

# A combination of what was animate.dem and world2.dem with the

# addition of saving the rotated image to an animated GIF.

# Requires GIF_ANIMATION

#

# History:

#   - 1. 3. 2006 Dan Sebald:  1st version

#    07 Jan 2006 Ethan Merritt:  Revise to assume terminal type is set by caller

#

# Caller must set terminal type.

# Example of intended use:

# set term gif animate transparent opt delay 10 size 200,200 background rgb 'black'
