Permission to use, copy, and distribute these images for any purpose and
|
|
without fee is hereby granted.
|
|
|
|
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.
