To make it more clear, you could add some css to change the mouse pointer to a hand/finger/whatever-your-system-uses to indicate that the image is a link.

I am searching for way to put hyperlinks into any of the graphics drawn using the functions e.g. jg.drawRect. I would like to associate a URL with this image. Any way in which I can do that? All help appreciated. Thanks in advance. Uttam. PS. I am planning to use this feature in my website www.agni-systems.com which is under development. Hello,

Just a new user of walter zorn’s incredible jsgraphics library of functions.

I am searching for way to put hyperlinks into any of the graphics drawn using the functions e.g. jg.drawRect. I would like to associate a URL with this image. Any way in which I can do that?

All help appreciated.

Thanks in advance.

Uttam.

PS. I am planning to use this feature in my website http://www.agni-systems.com which is under development.

I had a read through it, and it's a simple matter to use that as just a drawing library, instead of another SVG replacement. You know - this is pretty exciting! I'm really enjoying this project.

Maybe the two efforts can somehow be brought together. I'd like the idear of just integrating a Script and then using SVG as if every Browser did support it natively. About the Licenses: I simply didn't think of that problem. I’m not shure, but it seems as if Emil changed his plans to implement SVG via VML. Maybe the two efforts can somehow be brought together.

Christof, I'll be upgrading it soon to use that IE Canvas implementation that you pointed out, sometime soon. The only problem I have is with licenses. I give all my scripts out for free to anyone that asks for them, but I am always wary of any licensse of any kind, as I am not a legal type of person - the IE Canvas project uses the MIT license, and the jsGraphics library uses the LGPL license. I haven't a clue what those mean in real world terms. The biggest problem I have with those licenses is that they specify that a copy of the license must be included with each script (or "sizable portion" of the script). This is most annoying, as a bit of optimisation would reduce the actual scripts to a tiny fraction of the size of the licenses themselves. I would much rather a license that simply said something like this: <blockquote> this software is free, under the Kae license. you are free to use, re-distribute, and modify this code, as long as you don't place a restrictive copyright on it yourself. Have Fun. </blockquote> unfortunately, I haven't a clue if that is legally binding. right… it handles 100% of the basic primitives now.

I haven’t tried it out yet, simply because all the browsers on all of my machines support SVG (Internet Explorer with the Adobe plugin, of course). I might actually uninstall ASV on one of my machines just to see how his library works.

I've fixed that (characters cannot be pulled from strings with <code>str[charIndex]</code> - they must be pulled with <code>str.charAt(charIndex)</code>). Christof - I've never used the responseXML property, so didn't think of it ;-) Walter replied, saying that he would be adding functions (probably Bezier) to the library when he gets the time. I don't think he'll bother with anti-aliasing, though, so I suppose I'll need to hack that in myself. the code was not rendering in IE.

Why didn't you use the XMLHttpRequests reponseXML property? "Walter’s script does not yet support anti-aliasing or bezier lines, which I have mailed him about." Well, I guess that you will have to pay with a bad performance and memory penalty for anti-aliasing. Look at how Walters library works. Beziers can be aproximated by polygons - actually many GUI systems do it that way. “The parser reads the file in using the XMLHttpRequest object, then parses it into a walkable DOM-tree.”
