The MrSID Online Viewer for Windows allows users of Netscape and Internet Explorer (versions 4.0 or higher) to view MrSID imagery natively in either browser. The MrSID Online Viewer allows you complete control to zoom, pan, and navigate through larger and smaller zoom levels of MrSID imagery using your standard Web browser. The Online Viewer uses Selective Decompression to decode only the portion of an image necessary for viewing. Whether you're viewing imagery on your hard drive, your LAN, or across the Internet using a MrSID Image Server, the Online Viewer makes rapid viewing of large images possible, while maintaining maximum image quality.
