I believe that it makes sense for Flex to import SVG as an efficient mechanism for transcoding textual vector data down to a more efficient binary SWF represententation. As of yet, it has not made as much sense to do the extensive work necessary to support SVG DOM scripting, given that Flash has a more robust and better supported programming model. Purists get twitchy about our almost-but-not-quite-fully-standards-compliant implementation, but honestly, its often been tough to even justify a single concrete business case for implementing SVG at all. I think your use case is interesting, but at this level, it really wouldn't be rocket science for you to just import the XML at runtime and draw it yourself. It would not take: > The best solution is probably the one that doesn't require me > to be a complete Flash guru. :o) as your case is really very simple. Vectors and fills are at the trivial end of Flash gurudom. Another option might be to separate the data into multiple SVG "documents", and to composite the individual polygons using code. > Having the Flex server translate the SVG into the final SWF > sounds like the best solution to me, if it can be done.

I can imagine us providing some sort of access to the various subpieces of the SVG DOM from Actionscript, biased towards "getting stuff accomplished" rather than "pedantic standards compliance".

Am I seeing the problem correctly here? This is essentially correct, although I don't yet have a good example of the SVG that might be used.

Re: [flexcoders] Manipulating SVG
I apologize for the 2nd e-mail, but this is another example of a great response, but also one where we might begin to implement a protocol (as the poster was asking about pointers to resources), of, at the end of the message: SEE ALSO: 1. Title, url 2. Title, url I'm not trying to get anal about this; I just think it would dramatically cut down on people asking for more information as they could research it directly for themselves (note: not all posts make it clear how one would find the mentioned info.; let alone most of it is usually bleeding edge). -r --- John Dowdell <[EMAIL PROTECTED]> wrote: > Dave H wrote: > > Can anyone point me to any useful resources on > manipulating SVG from > > within Flex?

This is interesting. I was hoping someone else had a better answer than what I've currently got, but didn't want to leave it unanswered too. Let me make sure I'm correctly understanding what you'd like to do... it seems like there's some external mapping source which can give you a series of irregular polygons, with stroke/fill colors, in SVG format. You'd like these to display in the final SWF delivered to the audience, and would like to be able to programmatically change stroke/fill colors in response to user activity. Am I seeing the problem correctly here? If so, then I see two other possible paths, in addition to the "" path you mentioned, but I'm not sure which of these are viable paths, and hope that other people can expand on these. 1) Use a standalone SVG->SWF serverside utility to turn the mapping service's output into something very easily usable by the Macromedia Flash Player clientside renderer. (Some exist, but it would take some research to learn how closely current candidates match this project's needs.) 2) Have the Flex server request and translate the SVG data into the final SWF, where each polygon is still individually addressable. (Other people on this list know more than me here.) 3) Have the Macromedia Flash Player request the raw SVG data, and use procedural drawing to render and then manipulate the polygons. (ActionScript and the Drawing API have been used to render basic SVG files before... a search term "wahlers triolo svg" pulls up citations.) Are any of the above paths of interest...? jd -- John Dowdell . Macromedia Developer Support .

RE: [flexcoders] Manipulating SVG
The iteration book says only
The SVG people are horrified by Flex
http://svg.org/story/2004/07/01/111213/00
Flex, does not support interactivity, scripting, animation, masking
or filters.
And
Macromedia do not appear to provide a single valid piece of
documentation on SVG support in Flex
Can someone add this to the Flex wish list?
Thanks Dan

Subject: [flexcoders] Manipulating
SVG
Hi,
Can anyone point me to any useful resources on
manipulating SVG from
within Flex? I'd like to be able to
highlight different parts of an
image at the click of a button.
I have a simple graphic containing two polygons:
http://www.w3.org/2000/svg">
england"
id="england"
style="fill:#9F9; stroke:black"
d="M 35,10 L 50,10 55,40 60,40 65,60 40,70
15,65 15,55 30,40 35,10 z"/>
style="fill:none; stroke:black"
d="M 50,40 L 45,40 45,45 50,50 55,50 50,40 z"/>
If I embed the graphic into my application using
, what
happens to the object model, for example what's
the equivalent to:
document.getElementById('cambridgeshire').
setAttribute('style', 'fill:none; stroke:red');
Any pointers would be most appreciated! :o)
I'm using Flex 1.5.
Many thanks,
Dave
