Abstract

A method for interactively viewing raster images using scalable vector graphics (SVG), including receiving an SVG document, 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, passing the SVG document to an SVG viewer, rendering the SVG document, including 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, receiving the first portion of raster image data from the server computer, displaying the first portion of raster image data, transmitting a user request for a different portion of the raster image data, receiving a modified SVG document, modified according to the different portion requested by the user, passing the modified SVG document to the SVG viewer for re-rendering. A system and a computer readable storage medium are also described and claimed.

Claims

1. A method for interactively viewing raster images using scalable vector graphics, comprising:

transmitting an SVG document to a client computer, the SVG document including a reference to a raster image, the reference indicating a rectangular portion and a display width and height;

receiving an HTTP request from the client computer;

modifying the SVG document based on the HTTP request; and

transmitting the modified SVG document to the client computer.

2. The method of claim 1 wherein the reference to the raster image is placed within an <

image>

tag.

3. The method of claim 1 wherein said modifying the SVG document comprises modifying the rectangular portion within the reference to the raster image.

4. The method of claim 3 wherein said modifying the rectangular portion is based on characteristics of the client computer display.

5. The method of claim 1 wherein said modifying the SVG document comprises modifying the display width within the reference to the raster image.

6. The method of claim 5 wherein said modifying the display width is based on characteristics of the client computer display.

7. The method of claim 1 wherein said modifying the SVG document comprises modifying the display height within the reference to the raster image.

8. The method of claim 7 wherein said modifying the display height is based on characteristics of the client computer display.

9. A system for interactively viewing raster images using scalable vector graphics, comprising:

a transmitter for transmitting an SVG document to a client computer, the SVG document including a reference to a raster image, the reference indicating a rectangular portion and a display width and height;

a receiver for receiving an HTTP request from the client computer; and

an editor coupled to said transmitter and said receiver for modifying the SVG document based on the HTTP request.

10. The system of claim 9 wherein the reference to the raster image is placed within an <

image>

tag.

11. The system of claim 9 wherein said editor modifies the rectangular portion within the reference to the raster image.

12. The system of claim 11 wherein said editor modifies the rectangular portion based on characteristics of the client computer display.

13. The system of claim 9 wherein said editor modifies the display width within the reference to the raster image.

14. The system of claim 13 wherein said editor modifies the display width based on characteristics of the client computer display.

15. The system of claim 9 wherein said editor modifies the display height within the reference to the raster image.

16. The system of claim 15 wherein said editor modifies the display height based on characteristics of the client computer display.

17. A computer-readable storage medium storing program code for causing a computer to perform the steps of:

transmitting an SVG document to a client computer, the SVG document including a reference to a raster image, the reference indicating a rectangular portion and a display width and height;

receiving an HTTP request from the client computer;

modifying the SVG document based on the HTTP request; and

transmitting the modified SVG document to the client computer.
