Re: [svg-developers] Draw Arrow Head
raghu raman wrote: > I need to draw a arrow head in middle of the given path. > > Kindly let me know your solutions Raghu, this list is made of a bunch of helpful people that does its most to answer questions. If your question remains unanswered, I believe that's because there is no simple answer to it, ie. it involves quite complex computations, that are beyond my own knowledge. Even looking at fabled Kevin Lindsey's site, which is full of useful JavaScript geometrical algorithms, I see no simple solution (but perhaps I didn't looked hard enough). Perhaps you could explore it yourself to see if something fits your needs. In all cases, repeating your questions in different forms would probably not help much. You are not forgotten, but it is a delicate question. I believe SVG specs defined a function to calculate a path length, but I am not sure it is implemented in ASV3, and even so I don't see how to find the middle of the path, except by iterating perhaps. -- Philippe Lhoste -- (near) Paris -- France -- http://Phi.Lho.free.fr -- For servers mangling my From and Reply-To fields, -- please send private answers to PhiLho(a)GMX.net -- -- -- -- -- -- -- -- -- -- -- -- -- -- - To unsubscribe send a message to: [EMAIL PROTECTED] -or- visit http://groups.yahoo.com/group/svg-developers and click "edit my membership" Yahoo!

[svg-developers] Re: Draw Arrow Head
You could use to "animate" your symbol to 50% (using discreet values) and set fill "freeze" to make the symbol stay there. The advantage of this approach is that the symbol can be rotated automatically. See http://www.w3.org/TR/SVG11/animate.html#AnimateMotionElement or http://www.carto.net/papers/svg/samples/path_animation.shtml The other alternative would be to use javascript. The methods .getTotalLength() and .getPointAtLength() help you to find the position at 50% of the path. The tricky part is to find the orientation: for finding that you would have to read the path geometry itself ... As Philippe said, there is no easy solution for that.

[svg-developers] Performance
I am trying to build a scada mmi prototype with svg. For this I used a background image (1024x768 *.png or *.jpg file) and in foreground some simple dynamic controls like "led, bargraph, text, symbol,...). To get the dynamic behaviour, I used JavaScript and the DOM to change some attributes (text, color, visibility,...) of the controls once per second. I work with IE+ASV to show this graphic. There I get a really bad performance (97% CPU usage, 3s interval instead of 1s), if I don't use the attribute image-rendering="optimizeSpeed" at the background image element. When I use "optimizeSpeed" performance is ok, but I am not sure, if the quality of the graphic is sufficient for a comercial product. Is this a typical behaviour? Are there other ways to increase performance? I am looking forward to get response from anybody, who has some experience in this case.

Yes, I realized that, but what I didn't realize was that Mozilla and Netscape are actually the same browser. I guess that's where part of my confusion was. That is true, isn't it? > Which version of Netscape are you using BTW? Note that I already told > you there is no scripting link between ASV and recent versions of > Mozilla. I tried the latest version 7.2. Now that I've read about Mozilla/Netscape and SVG support on the links that people have provided, I'm confused as to how my app even displayed an svg image at all. I have two embedded svg images in my html. The one that does not try to communicate with html displays fine. The other one that does try to communicate with html won't display (probably because it tried to communicate with html). Since I'm using Netscape 7.2, I didn't think there was any svg support at all. So why is one of my svg images displaying with Netscape 7.2? > My advice to you is to download a *Mozilla Suite or Mozilla Firefox* > build with *native* SVG support and get things working in that.

You need to add some extra calculation when defining clipPath (added "M 0,30 ... L500,2000" at the extremes, indipendently of the "M0,0h2000v2000H0" box which is added to justify clip-rule="evenodd").

I need to maintain current information that I will need to display in a textual listing when the user clicks on a link.

How would I do this if I didn't use js arrays to store that data? Also, how do you display text listings using svg?

I was about to write, after looking back at the example path, that since it is made only of straight lines, it should not be so hard to compute total length and then to iterate to find the middle. My initial answer was about generic paths, with Bézier and all. Now, your solution is much easier, using the viewer to do the hard computations...

And it's not in HTML format (I always print things out anyway). I just wanted to add a tutorial other than what is already found on the Beatware forum http://www.beatware.com/forum/ I'm getting my students to create SVGT files for projects for the rest of the semester. They'll be very basic, but may help with examples/samples of SVGT content on-line. Any suggestions (and I'm getting some good ones) for projects are welcomed! Thanks much!

Should work well. Maybe at a later SVG version we should have a declarative approach for that problem, without having to use scripting or animation.

[svg-developers] Re: Draw Arrow Head
Hi, you could also define your own font and use textPath to place markers (glyphs) anywhere along a path setting the startOffset attribute - doing so, orientation is no problem either. Sample: http://www.zuccaralloo.de/devgroup/samples/textPathMarkers.svg A glyph can be a simple path or any SVG content (see the spec chapter 20.4). So this is as flexible as using symbols. In your example you would have to adjust the font-size according to the scaling that is done when you use viewBox - similar to adjusting the stroke-width of your path. Your sample with an arrow at the middle of the path - and a little animation that just happened to get in there when I was playing :-) http://www.zuccaralloo.de/devgroup/samples/textPathMarkers2.svg I hope it's not too confusing and you will get the basic idea. I guess then you can start to try and play!

Re: [svg-developers] Performance
Hi Friedheim, I agree with Domenico. SCADA using SVG synopthics is my main job, since over 2 years. I have several examples of SVG's taking almost no CPU. The worstest problem (I'd say "fault") of SVG is that you cannot control how much the SMIL animation can eat CPU. So most of the time you have to manage the code (losing even lot of time) to adjust animations so that the CPU is within acceptable margins. Don't refuse the Javascript+DOM animation: in many situations it would be convenient.

[svg-developers] Issues using postUrl with .NET Webservice
Hello,
I am new to programming in svg and c#. I have recently attempted to
use postUrl but I have been having problems making it work. I have
spent many hours searching the internet and news groups for answers
but there isnt a detailed enough example to help out.
Here is the scenario:
I am trying to take data from svg using Adobe 3.0 viewer and post it
back to a .NET c# webservice. I have a variable I want to send back
so I can process the post using different functions. Here are my
issues.
1. What is the correct format to send the variable back to the
webservice
2. How do I access the sdata (post back part) from the webmethod and
place the string into returneddata
Currently, the postStatus returns success with a message 'Request
format is invalid: text/xml.' The webservice will post correctly in
debug mode in vs.net. I dont see any data in my dsname variable or
anywhere else.
Your help would be greatly appreciated.
Thanks,
Mike
Code Example below:
SVG Code (Fragemented code example)
--
function postStatus(urlStatus)
{
if(urlStatus.success)
{
//I keep getting 'Request format is invalid: text/xml.'
alert( urlStatus.content);
}
else
{
alert("Something went wrong with posting data!");
}
}
function postData()
{
var webServicePostUrlString
= "/WebService/handleData.asmx/postedData?dsname=dataset1";
sdata="hello World"; // This could also be a svg fragement using
printNode
postURL(webServicePostUrlString, sdata, postStatus, 'text/xml', null)
}
C# Web Service
--
[WebService(Namespace="http://localhost/webservice/";)]
public class handleData : System.Web.Services.WebService
{
[WebMethod(Description="Get Data from client to server.")]
public void postedData(string dsname)
{
//How do you get the data into returneddata from the postUrl?
string returneddata="?";
switch(dsname)
{
case "dataset1":
processDataSet1(returneddata);
break;
case "dataset2":
processDataSet2(returneddata);
break;
}
}
}
