   9 These 15 images are part of the much larger PngSuite test-set of
  10 images, available for developers of PNG supporting software. The
  11 complete set, available at http:/www.schaik.com/pngsuite/, contains
  12 a variety of images to test interlacing, gamma settings, ancillary
  13 chunks, etc.

  15 The images in this directory represent the basic PNG color-types:
  16 grayscale (1-16 bit deep), full color (8 or 16 bit), paletted
  17 (1-8 bit) and grayscale or color images with alpha channel. You
  18 can use them to test the proper functioning of PNG software.
