Permission to use, copy, and distribute these images for any purpose and

These 15 images are part of the much larger PngSuite test-set of
images, available for developers of PNG supporting software. The
complete set, available at http:/www.schaik.com/pngsuite/, contains
a variety of images to test interlacing, gamma settings, ancillary
chunks, etc.
The images in this directory represent the basic PNG color-types:
grayscale (1-16 bit deep), full color (8 or 16 bit), paletted
(1-8 bit) and grayscale or color images with alpha channel. You
can use them to test the proper functioning of PNG software.

* =========================
*
* March 8, 2002
* March 26, 2002
*
* Since the PNG Development group is an ad-hoc body, we can't make
* an official declaration.
*
* This is your unofficial assurance that libpng from version 0.71 and
* upward through 1.2.2beta4 are Y2K compliant. It is my belief that earlier
* upward through 1.2.2beta5 are Y2K compliant. It is my belief that earlier
* versions were also Y2K compliant.
*
* Libpng only has three year fields. One is a 2-byte unsigned integer
