-Permission to use, copy, and distribute these images for any purpose and
-without fee is hereby granted.
-
-The 15 "bas*.png" 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 "ft*.png" images are "free/libre" replacements for the transparent
-corresponding t*.png images in the PngSuite.
-
-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.
