Two images (ftbbn0g01.png and ftbbn0g02.png) are by Glenn Randers-Pehrson, 2012
|
|
|
|
Permission to use, copy, modify, 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 "i*.png" images are the same images, but interlaced.
|
|
|
|
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.
