Even if the image is necessarily generated on the fly, you can't tell what resolution of printer will be used for a proof and for a quality hard copy, and you can't know whether the image will be saved and viewed on a different resolution display, or whether the window will be resized after the download. If the image can reasonably be pre-computed, dynamic sizing will make it uncacheable, which is an undesirable attribute for any web page. You would need to have several resolutions and contents negotiate. There are proprietory HTTP headers that ought to allow content negotiations and and I believe there a proposals for a standard way for clients to inform the server of their capabilities. -- --------------------------- DISCLAIMER --------------------------------- Any views expressed in this message are those of the individual sender, except where the sender specifically states them to be the views of BTS. >
