The Seybold show held this week in San Francisco saw both Corel and Extensis align themselves with Apple's updated Mac OS X operating system. Extensis revealed Suitcase 10 for Mac OS X, while Corel unveiled KPT Effects for both Mac OS and Windows, and CorelDraw 10 for Mac OS X. Suitcase 10, which will start shipping on November 19, 2001, will make activating, previewing, and managing fonts faster and easier than before, says Extensis. The update will be available to all registered Suitcase 10 owners free of change, says the company. Corel KPT Effects, shipping under Corel's Procreate banner, is a collection of nine plug-ins for Adobe Photoshop and compatible applications. Effects include Lightning, Fluid, Hyper Tiling, Pyramid Paint, Scatter, Ink Dropper, FraxFlame II, Gradient Lab, and Channel Surfing. Fluid lets users make an image that looks as if it is floating on a pool of liquid. Users can add liquid distortion effects to images and create short animations. Ink Dropper, meanwhile, adds drops of liquid to a surface to create everything from water spots to smoky swirls. It will cost £149.99 plus VAT, and will ship in October for Mac and Windows. Corel also revealed plans to bring its Corel Graphics Suite to the Mac, with support for Mac OS X. The suite includes CorelDraw 10, Corel Photo-Paint 10, and Corel RAVE - its animation package with Flash export. New features, according to the company, include enhanced interactive tools, improved publish to the Web features, and a new colour management interface that has won industry praise. A pre-flight engine has been added, as well as a Web image optimizer. It will cost £399.99 plus VAT, with an upgrade price of £199.99 plus VAT from CorelDraw 6.0.
