It has come to my attention that both Unisys and IBM obtained patents on the Lempel Ziv Welch (LZW) data compression and decompression algorithm that is used in GIF files. The language viewer in my Web Access Gateway uses GIF files for its foreign characters. Many users rely on this because their browsers are old or limited and cannot display the PNG format. Therefore, I have modified the GIF files so that they do not use the Lempel Ziv Welch (LZW) data compression algorithm and do not infringe the patents on that algorithm. The files are larger, but they do not infringe.
(The patents should now have expired, but I’m no longer actively maintaining the language viewer images so I have no plans to reverse the above change. Web Adjuster has more modern image rendering.)
