		        Image Release Notes
			
This archive contains all of the different resolution image
files generated from the "Evil Empires: One down, one to go..."
bumper sticker available from:

    http://www.fourmilab.ch/evilempire/

All images are in Portable Network Graphics (PNG) format.  The
evilempires_16881.png is the full resolution (16881×5553 pixel)
image generated from the PostScript page description at 1600
dots per inch resolution.  The other images were generated from
it by sub-sampling this image, which anti-aliases ragged edges
in the full resolution image.  For publishing applications,
choose the next larger image than you need and scale it down to
the required size.

The images in this archive are as follows:

         File name           Width       Height     Anti-Aliased?

    evilempires_16881.png   16881         5553        No

All images are interlaced.  Note that PNG compression works
sufficiently well on images of this kind that file sizes do not
increase remotely in proportion to the number of pixels in the
image; files containing larger images are bigger mostly due to
the finer-scale anti-aliasing of edges.
