Unisys holds a patent for the compression algorithm that GIF images utilize. Some years back, they thought they could charge anyone that 'used' their technology. However, they lost big time in courts, for the reason they can never charge for propriaty work created with their technology. What they CAN cherge for is the use of their algorithm. This holds true for EVERY work created with whatever technology was used. Ie, Borland could NEVER charge me for my work I created using Delphi, for which Borland holds several patents. They can only charge me for using their product/technology. That is why software developers using the GIF compression algorith have to pay a royalty fee for every 'sold' copy of their software which contains that algorithm, to Unisys. End users DO NOT have to pay anything for creating or using GIF images!!! It is time that this urban myth dies already. So feel free to use GIF images all you want, you already 'paid' your right to use them, through your purchase of your favorite image editor. -- Erwin Dokter mailto:edokter@xxxxxxx http://members.home.nl/edokter To unsubscribe, send a message to listar@xxxxxxxxxxxxxxxxx with "unsubscribe calmira_tips" in the body.
