| |
| 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. |
