6. A system for interactively viewing raster images using scalable vector graphics (SVG), comprising: a receiver for (i) receiving an SVG document from a server computer, the SVG document including a reference to a raster image within the SVG document, the reference indicating a rectangular portion, a display width and height, and an IP address for a server computer, (ii) receiving a modified SVG document from the server computer, modified according to a different portion, and (iii) receiving a portion of raster image data from the server computer; a transmitter for (i) requesting from the server computer a first portion of raster image data corresponding to the rectangular portion, display width and display height, the first portion of raster image data being derived from the raster image, and (ii) requesting a different portion of the raster image data; and an SVG renderer operatively coupled with said receiver and said transmitter for rendering an SVG document, comprising a raster image processor for displaying a portion of raster image data.
