671242f350d172e106580348e24bab66b0d7e6a5vboxsyncThese 15 images are part of the much larger PngSuite test-set of
671242f350d172e106580348e24bab66b0d7e6a5vboxsyncimages, available for developers of PNG supporting software. The
671242f350d172e106580348e24bab66b0d7e6a5vboxsynccomplete set, available at http:/www.schaik.com/pngsuite/, contains
671242f350d172e106580348e24bab66b0d7e6a5vboxsynca variety of images to test interlacing, gamma settings, ancillary
671242f350d172e106580348e24bab66b0d7e6a5vboxsyncchunks, etc.
671242f350d172e106580348e24bab66b0d7e6a5vboxsyncThe images in this directory represent the basic PNG color-types:
671242f350d172e106580348e24bab66b0d7e6a5vboxsyncgrayscale (1-16 bit deep), full color (8 or 16 bit), paletted
671242f350d172e106580348e24bab66b0d7e6a5vboxsync(1-8 bit) and grayscale or color images with alpha channel. You
671242f350d172e106580348e24bab66b0d7e6a5vboxsynccan use them to test the proper functioning of PNG software.
